Preparing for InstallationSummary of Configuration Tasks

CAUTION: Resetting the ZoneFlex 7731 to its factory defaults will result in loss of all configuration settings, including the provisioning (pairing of the Root and Non-Root Bridge) settings. If you do need to reset to defaults, you will need to re-provision the bridge. In factory default state, the role of all 7731 units is Root Bridge. Therefore, running the factory default procedure on any ZoneFlex 7731 results in that unit becoming unreachable on the non-root bridge default IP address (192.168.2.254).

4 Preparing for InstallationThis section describes the configuration procedures required before you proceed to mount the ZoneFlex 7731 Wireless Bridge units in their permanent locations. These tasks should be performed prior to connecting any ZoneFlex 7731 to your live network.

Summary of Configuration TasksIf you have purchased the standard two unit package, the Root Bridge and Non-Root Bridge will have already been preconfigured at the factory. Therefore, you will only need to access both units and set the Country Code prior to installation (unless your country is United States, in which case, Country Code is also preconfigured). Then you can go directly to “Physical Installation”.

If you have purchased a single Wireless Bridge, to expand your network to a point to multipoint configuration, or replaced one of the units, or have decided to reset the units to factory defaults for any reason, the following tasks should be performed prior to physical installation:

1. Provision one ZoneFlex 7731 as the Root Bridge, and the remaining units as Non-Root Bridges.

2. Access the Wireless Bridge Web interface using an administrative computer.

3. Set the country code to your current location.

4. Change other configuration settings (optional).

5. Verify association between the Root and Non-Root bridges.

NOTE: If you purchased your Wireless Bridge in the United States, the country code is fixed to “United States” at the factory and is not user configurable. If not, you must set the country code to your location prior to mounting to ensure compliance with national regulatory requirements.

10

Preparing for InstallationWhat You Will Need

CAUTION: If changing the Country Code over the air, you will need to configure the remote units first followed by the local unit, to avoid loss of connectivity.

In addition to setting the country code (required), the following optional configuration settings may be changed at this time:

■ Change the device names, SSID, shared secret, user names and passwords■ Manually assign static IP addresses■ Enable SNMP or FlexMaster network management■ Configure security settings■ Configure management VLAN

To customize any of these settings before deploying the bridge pair, you will need to connect an administrative computer directly to each ZoneFlex 7731, and provide power using either DC power or Power over Ethernet before you can access the Web interface.

The default IP addresses for the Root and Non-Root Bridge are as follows:

■ Root Bridge: 192.168.2.1■ Non-Root Bridge: 192.168.2.254

CAUTION: In factory default state, the role of all 7731 units is Root Bridge. Therefore, running the factory default procedure on any ZoneFlex 7731 results in that unit becoming unreachable on the non-root bridge default IP address (192.168.2.254).

What You Will NeedBefore starting with the configuration tasks, make sure that you have the following requirements ready:

■ An administrative computer running Microsoft Windows (2000/XP/Vista/7)■ Microsoft Internet Explorer (6.0 or later) or other browser such as Firefox, installed on

the administrative computer■ Two Ethernet cables (Cat-5e or better)■ PoE injector (if not supplied with the Wireless Bridge, you can purchase a third party

802.3af-compliant PoE injector or switch)■ 6mm Phillips screwdriver

If you are planning to power the Wireless Bridge using a 12 VDC connection, you will also need the following:

■ One 3.1mm-3.3mm UL1185 (80°, 300V) single shielded DC cable■ 12 VDC, 1A DC power source (for example, a battery)■ 3mm Phillips screwdriver

11

Preparing for InstallationPoint to Point Bridge Configuration

Point to Point Bridge ConfigurationThe following section provides instructions for configuring two ZoneFlex 7731 Wireless Bridges for point to point bridging.

If you will be deploying more than one Non-Root Bridge, Ruckus Wireless recommends first completing the Point to Point Bridge configuration, before proceeding to “Point to Multipoint Configuration” on page 20.

CAUTION: Do not attempt to access the Web interface of two ZoneFlex 7731 units at the same time by connecting both to the same Layer 2 switch or to the same broadcast domain on a live network. This will cause a network loop, which can disrupt your entire network.

Step 1: Supply Power to the Wireless BridgeThis procedure assumes that you will be using Power over Ethernet for the pre-installation configuration, even if you plan to use DC power in the final deployment. For DC power setup, see “Use DC Power” on page 32.

NOTE: You only need to connect one type of power source at this point, even if you areplanning to use both PoE and DC power in your final deployment.

Use Power Over Ethernet

1. Take out the PoE injector and the power adapter from the Wireless Bridge package.

2. Obtain two Ethernet cables.

3. Connect one end of one Ethernet cable to the AP/BRIDGE port on the PoE injector, and then connect the other end to the RJ45 port on the ZoneFlex 7731.

4. Connect one end of the other Ethernet cable to the NETWORK port on the PoE injector.

5. Connect the power jack to the DC 48V IN connector on the PoE injector, and then plug the power adapter into a power source. The single LED on the PoE injector turns red.

6. Check the power LED on the ZoneFlex 7731 to ensure power is being supplied to the bridge.

12


Figure 5. Connect the Ethernet cables and power adapter to the PoE injector

You have completed connecting the Wireless Bridge to a PoE power source.

Step 2: Auto Provision the Root and Non-Root BridgesThe first configuration task (after you have supplied power) involves provisioning one ZoneFlex 7731 as the Root Bridge and the others as Non-Root Bridges. Two methods are available:

■ Auto Provisioning■ Manual Provisioning

Auto ProvisioningWhen in factory default state, you can designate one ZoneFlex 7731 as a Root Bridge and another as a Non-Root Bridge by simply providing power to both units and connecting them directly to each other with an Ethernet cable. This Auto Provisioning process chooses the device with the lower MAC address and provisions it as the Root Bridge, while the device with the higher MAC address is automatically provisioned as the Non-Root Bridge. If you want to have more control over which is the Root and Non-Root Bridge, you should choose Manual Provisioning.

Auto provisioning can only be performed on two ZoneFlex 7731 units - if you will be using more than two, you will need to manually provision the third unit.

To Auto Provision two ZoneFlex 7731 Wireless Bridges

1. Provide power to both bridges and connect them together directly via an Ethernet cable (you can power up and then connect, OR connect and then power up both units).

2. The LAN LED on both units (LED 2) should be solid green, indicating that the units are connected to each other. At this point, if both units have been reset to factory defaults, neither has yet been provisioned as Root or Non-Root.

3. Once both units are powered on and physically connected, LED 5 and 6 (labeled P0 and P1) on both units begin alternately blinking, indicating that the role is unknown and provisioning is in process. This process takes about 10 to 20 seconds.

4. Simultaneous rapid blinking of these two LEDs indicates that provisioning is complete.

5. After provisioning is complete, LED 4 (ROLE) indicates which unit is the Root and Non-Root unit. The ROLE LED is solid yellow for the Root Bridge while the Non-Root Bridge’s ROLE LED is OFF.

6. Take note of which unit is the Root Bridge and which is the Non-Root Bridge.

7. When the auto provisioning process is complete, you must reboot both units. A reboot is triggered by disconnecting the Ethernet cable.

8. During the reboot only the bottom LED, PWR is lit. Once the reboot completes you will see activity on the WLAN LED, indicating wireless communication between the pair.

You have completed auto provisioning the Root and Non-Root Bridge pair.

Figure 9. Ruckus ZoneFlex 7731 Wireless Bridge Status :: Wireless page

8. Continue to “Step 6: Change the Country Code”.

17


Step 6: Change the Country CodeChange the Country Code setting to your location and reboot the bridge for updates to take effect.

CAUTION: If changing the Country Code after the units have been mounted, you will need to configure the remote units first followed by the local unit, to avoid loss of connectivity.

NOTE: If you purchased the Wireless Bridge in the United States, this value is fixed to “United States” at the factory and is not user configurable.

If you purchased the Wireless Bridge outside of the United States, verify that the value is set to your country or region. Selecting the correct country code ensures that the Wireless Bridge uses only the radio channels allowed in your country or region.

To set the country code to your location:

1. On the Configuration > Wireless page, select your location from the Country Code menu.

2. The following warning message appears:

Figure 10. Country code warning message

3. Click OK to continue.

4. A reboot initiates immediately, and the Reboot in Progress screen is displayed.

18


Figure 11. Reboot in progress

5. When the reboot is completed, log in again to continue making configuration changes.

6. You have completed setting the Country Code. Continue to “Step 7: Verify Association between the Bridges”.

Step 7: Verify Association between the BridgesOnce the initial configuration procedures have been completed, verify that your Wireless Bridges have associated with one another. If no association has been established, the following will be displayed:

Figure 12. No association established

19


The units will automatically associate with one another within approximately 1 to 2 minutes. Once the association is complete, the page will refresh and the Connected Device information will be displayed, as shown:

Figure 13. Association established

If no association is established after a few minutes, ensure that the Country Code, SSID and Passphrase are set to the same values, and that Channel is set to SmartSelect (or to the same channel, if set manually). If you have made sure all these settings are the same and the bridges still fail to associate, the Web interface provides several tools for diag-nosing the problem, which can be found on the Administration > Diagnostics page. Tools include Ping, Traceroute, Show ARP Table and Show FDB Table.

20

Preparing for InstallationPoint to Multipoint Configuration

Figure 14. Administration :: Diagnostics page

You are now ready to begin the physical installation.

Point to Multipoint ConfigurationFor point to multipoint configuration, you will need to manually provision any additional Non-Root Bridges, as the Auto Provisioning procedure will only provision one Root and one Non-Root Bridge.

Additionally, you will also need to assign a static IP address to the second Non-Root Bridge (unless IP addresses are assigned by DHCP), to prevent multiple Non-Root Bridges from using the same address (192.168.2.254).

NOTE: The maximum number of Non-Root Bridges that can connect to a single Root Bridge is 4.

Manual ProvisioningIn addition to Auto Provisioning, there are two methods of manual provisioning:

■ Manual Provisioning using the Web Interface■ Manual Provisioning using a Local File

Manual Provisioning using the Web InterfaceThe ZoneFlex 7731 Wireless Bridge can be manually provisioned using the Web interface. This method may be preferable if you are installing more than one Non-Root Bridge, or if you want to have more control over which unit is designated Root and Non-Root.

21


To manually provision a ZoneFlex 7731 as a Root or Non-Root Bridge

1. Connect the Admin computer directly to the ZoneFlex 7731 (see “Step 3: Prepare the Administrative Computer” on page 13).

2. Open a Web browser (Internet Explorer) and enter the default IP address in the URL bar (default IP: 192.168.2.1).

3. Enter the Username and Password (default username: super; default password: sp-admin) and click Login.

4. If the unit has not yet been provisioned (factory default state), the Manual Provisioning Wizard launches automatically immediately after login, as shown in Figure 15.

Figure 15. Manual Provisioning Wizard

5. Select Root Bridge or Non-Root Bridge and click Next to continue.

6. Adjust settings on the WLAN configuration page if necessary. You may want to change the SSID and Passphrase to something easy to remember at this point--you can change them again after installation for increased security.

7. Set the Country Code to your location.

8. Write down the SSID, encryption settings and Passphrase, as these values will need to be identical so that the Root and Non-Root Bridges can communicate with each other.

9. Click Next to continue. The “Your Setup” configuration summary page appears.

10.Click Reboot to confirm changes and reboot the bridge. Once the reboot is complete, the manual provisioning is complete.

22

Physical InstallationDetermine the Optimal Mounting Location and Orientation

Determine the Optimal Mounting Location and OrientationThe location and orientation that you choose for the Wireless Bridge play a critical role in the performance of your wireless network. In general, Ruckus Wireless recommends installing Wireless Bridges away from obstructions and sources of interference and ensuring that the Wireless Bridges are in direct line of sight of one another.

NOTE: Ruckus Wireless recommends installing the Root Bridge on the network side of the bridged link and the Non-Root Bridge on the remote side.

Figure 19. Recommended orientation for optimal performance

Direct Line of Sight

25

Physical InstallationBecome Familiar with the Installation Components

Point to Multipoint OrientationIn a point to multipoint configuration, there are many factors to consider. First, note that the maximum angle from the Root Bridge is 30 degrees. As you get closer to the maximum angle from the Root Bridge, throughput performance decreases. If you go beyond 30 degrees, performance will be drastically impacted to the point that the connectivity may be lost entirely.

Second, consider the difference in distance from the Root Bridge. If one Non-Root Bridge is at placed at the maximum distance from the Root Bridge (approximately 20km), and the other is very close, performance may be impacted due to different time delays between the two transmission links.

Some examples of recommended and non-recommended orientations are below.

Figure 20. Recommended and non-recommended orientations

Become Familiar with the Installation ComponentsThe ZoneFlex 7731 Wireless Bridge is designed for installation in an outdoor environment, such as an exterior wall, or the roof overhang of a building, or a streetlight pole.

Take note of the components that must be installed indoors and outdoors. The PoE injector and power adapter that are shipped with the Wireless Bridge are for indoor use only. Surge protectors should be installed near the Wireless Bridge and near any connections where cables enter the building. Ruckus Wireless also strongly recommends that you form a drip

loop on any cable that is connected to devices that are installed outdoors (for example, the Wireless Bridge and the Ethernet surge protector), to prevent water from running along the cable and entering electrical components.

Decide How You Will Supply Power to the Wireless BridgeThe Wireless Bridge supports Power over Ethernet (PoE) and 12 VDC power and can be connected to both power sources at the same time. If you connect the Wireless Bridge to both PoE and DC power sources at the same time, it will use DC as the primary power source and PoE as the backup power source. Refer to the following sections depending on which power supply method you will use:

■ Using Power over Ethernet■ Using DC Power

WARNING: Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

WARNING: Installation of this equipment must comply with local and national electrical codes.

CAUTION: Make sure that you form a 3”-5” drip loop in any cable that will be placed outdoors. This will prevent water from running along the cable and entering the Wireless Bridge, the surge protector or the building where the cable terminates.

CAUTION: Be sure that grounding is available and that it meets local and national electrical codes. For additional lightning protection, use lightning rods and lightning arrestors.

.

WARNING: The Ruckus Wireless PoE injector (if supplied with your Wireless Bridge) is for indoor use only. Never mount the PoE injector outdoors with the Wireless Bridge.

Aiming■ Aiming in a Point to Point Deployment■ Aiming in a Point to Multipoint Deployment

Aiming in a Point to Point DeploymentOnce both units are installed in their permanent locations, press the Aiming Button on the outside of either unit to begin aiming. Alternatively, you can start the aiming process via the Web browser, by clicking Start Aiming on the Status > Wireless page.

The following section describes the procedure for aiming a pair of ZoneFlex 7731 Wireless Bridges in a point to point configuration. For information on aiming in a point to multipoint deployment, see “Aiming in a Point to Multipoint Deployment” on page 51.

1. Press the blue button on the side of either bridge and hold it for 4 seconds.

• The bottom LED turns yellow, indicating that the unit is in Aiming Mode. • If the unit is in Aiming mode but there is no association between the two bridge

units, all LEDs will cycle yellow until the two ZoneFlex 7731 units have associated.

2. Adjust the azimuth and elevation of the first unit to maximize the Aiming LED indica-tors. RSSI (received signal strength indication) values are shown in Table 5.

50


3. After one unit is at its maximum link level, adjust the second unit to increase the link performance.

4. If the unit's elevation adjustment needs to be reversed, remove the 4 bolts mating the two mounting bracket pieces together. Remove the 4 mounting screws attaching the bracket to the ZoneFlex 7731 enclosure, rotate the bracket 180º and reattach the bracket to the enclosure. Repeat steps 2 through 7. Adjust the ZoneFlex 7731 to your desired orientation.

NOTE: The cable end of the ZoneFlex 7731 should always be pointing down.

5. Once the ZoneFlex 7731 is in the proper orientation, tighten the thumb screws flush to the bracket.

6. Using a 10mm ratchet wrench, tighten the two hex bolts to fix the unit's orientation. The bolt torque value must be 0.6-0.8 Newton meter (Nm).

7. Verify that the ZoneFlex 7731 link performance has not changed.

8. Press the blue Aiming button once again to stop aiming.

9. Repeat steps 1-8 for the other bridge unit.

NOTE: If the unit is mounted in a position that does not allow the user to view the LEDs, the Web UI can be used for Aiming. On the Status > Wireless page, pressing the “Start Aiming” link is the same as pressing the blue Aiming button. The Signal Strength is shown on the Web page. More green bars indicate higher signal strength.

10. If using the Web interface for aiming, adjust the orientation of the units to maximize the green bars under “Signal Strength.”

11.For more precise aiming, the value under “ACK RSSI” can also be used. A higher ACK RSSI indicates better signal strength. Both the green bars in the Web interface and the LEDs on the outside of the bridge units serve as indicators of ACK RSSI values.

NOTE: For best results, it is important to perform the aiming procedure for both units.

Aiming in a Point to Multipoint DeploymentIn a point to multipoint installation, the procedure is slightly different.

1. Choose the “optimal pair” (one Root and one Non-Root) for your network. The “optimal pair” can be determined by placement location, throughput requirements, or other factors.

• For example, if you are installing three Non-Root Bridges spaced approximately even in angle from the Root Bridge, you would likely want to choose the middle one, as shown, for an optimal balance of performance for all three.

2. Complete the point to point aiming procedure for this “optimal pair” first, as described in “Optimizing the Distance, Orientation and Channel” on page 48.

3. Repeat the aiming procedure for each additional Non-Root Bridge, while leaving the Root Bridge fixed.

4. Once you have completed the aiming procedure for all Non-Root Bridges, proceed to “Verifying the Connection”.

52

Optimizing the Distance, Orientation and ChannelChannel Optimization

Figure 45. Choosing the “optimal” pair in a point to multipoint deployment

Channel OptimizationAfter the aiming process is complete the first time, the Root Bridge automatically initiates a channel scan to determine the optimal channel for the specific environment. Once it has scanned each channel and determined which channel provides the best performance, the Root Bridge sends a message to all Non-Root Bridges informing them of the proper channel to use.

You can also manually initiate this channel scan process at any time. Ruckus Wireless recommends manually running the channel optimizer again each time additional Non-Root Bridges are added (after the Aiming process is complete).

To manually initiate the Channel Optimizer Process:

1. Go to Status > Wireless on the Root Bridge Web interface.

2. Click the Start Channel Optimizer Process link.

3. The Channel Optimizer begins immediately.

4. The LEDs on the Root Bridge cycle orange until the process is complete.

5. Wait for the Channel Optimizer to complete scanning, and it will automatically configure the Root and Non-Root Bridges with the appropriate channel. The time it takes for the process to complete depends on the number of channels available in your country or region.
