5. Install the switch hardware. Unplug the AC power from the switch before installing the switch hardware.

■ Rack mounting: Use a #1 Phillips (cross-head) screwdriver to attach the accessory kit brackets to the switch using the eight 8-mm M4 screws. Then use the four number 12-24 screws to secure the brackets to the rack.

Note: A rail kit is available for mounting the switch in 4-post racks. For more information, see the switch Installation

and Getting Started Guide.

■ Horizontal surface mounting: Attach the four self-adhesive pads (included in the accessory kit) to the bottom corners of the switch and then place the switch on a stable horizontal surface.

6. Connect network cables.

Note: For transceiver connections, install and use only HP SFP transceivers supported by the switch.

See “SFP Installation Notes” on page 4.

7. (Optional) Connect stacking cables. If you are stacking multiple HP 2920 switches together, then connect them into a supported stacking topology using HP 2920 Stacking Modules and stacking cables. For more information on supported stacking topologies, see the switch Installation and Getting Started Guide.

Caution: Make sure to connect the stacking cable with the

pull tab on the top. Insert the cable until it clicks into place.

To disconnect the cable, pull on the pull tab.

8. Power On the switch. As shown in step 3.

9. (Optional, when using an HP 640 RPS/EPS with your Switch 2920)

Connect RPS/EPS power cables.

On the 640 RPS/EPS, connect the RPS/EPS power cable intoany of the connectors for the power supply slot that you areusing. Then hand tighten the retaining screw. Make sure thatyou do not overtighten the screw.

Then, also connect and secure the RPS/EPS power cable to the switch.

IMPORTANT: See the HP 640 RPS/EPS Installation and Power Setup Guide for supported RPS/EPS-to-switch

power topologies and basic configuration information. Each of the power supplies installed in the 640 RPS/EPS

can provide redundant power to any one of multiple HP 2920 switches, and can also provide additional PoE/

PoE+ power for multiple HP 2920 PoE+ switches. But, failure to connect the devices together in a supported

topology can cause unexpected results.

To use the HP 640 RPS/EPS with your HP 2920 Switch, software version WB.15.13.xxxx or later must be installed

on the switch.

For additional and more detailed switch configuration information, see the switch Management and

Configuration Guide.

For PoE/PoE+ information for the HP 2920 Switches being used without an HP 640 RPS/EPS, see the HP Power over Ethernet

(PoE/PoE+) Planning and Implementation Guide.

SFP Installation Notes

■ Revision “B” or later SFP transceivers only. This switch requires revision “B” or later SFP transceiver products – the product number ends with the letter “B” or later (for example, J4858B, J4859C).

■ Use only genuine HP transceivers. For a list of HP SFP or SFP+ transceivers supported by various HP switch products, visit www.hp.com/networking/support:1. In the first text box, type J4858 (for 100-Mbps and Gigabit information), or J8436 (for 10-Gigabit information).

2. Select any of the products that display in the drop down list.

3. Select Product support information. Then click on Manuals and find the Transceiver Support Matrix.

■ Hot Swapping transceivers. The transceivers that you can install in your HP switch can be “hot swapped” — removed and installed after the switch is receiving power. You should disconnect the network cables from the transceivers

before hot swapping them.

Best practice tip: After inserting a transceiver into a switch, the Mode LED will be briefly while the transceiver is initialized. Do not remove the transceiver until the Mode LED has turned off.

When you replace a transceiver with another transceiver of a different type and then execute the write memory command through the switch console, the switch configures the port on the new transceiver with the default speed and duplex settings used for the new transceiver type. The default for the transceivers is Auto. Note that the switch retains other port-specific configuration settings, such as trunking, Spanning Tree Protocol (STP), and VLAN values that were configured for the previous transceiver.

10. Confirm each RPS/EPS power cable connection. Check the LEDs on the front of the 640 RPS/EPS and the switch. On the 640 RPS/EPS, the Device Connected LED for the connector that you have used (for example 1A) will be on solid green. On the switch, the XPS LED will be on solid green. If either of the LEDs does not appear this way, then refer to the “Troubleshooting” chapter in the switch Installation and Getting Started Guide.

11. (Optional) Configure the switch for management.

By factory default, the switch will automatically obtain its IP network configuration from a DHCP or BootP server. Subsequently, you can determine the IP address assigned to the switch by inspecting your DHCP/BootP server, or by using LLDP from a connected device.

You can also manage and configure the switch through a console port connection. Connect a VT-100 terminal or PC (with suitable terminal emulation software) to the switch using the serial cable (DB-9 and RJ-45 connectors) supplied with the switch.

* Note: You can also connect a console to the switch via the USB console port (cable not provided). For more information on using the USB console port, see the switch Installation and Getting

Started Guide.

For information on configuration and remote management, see the switch Management and Configuration Guide. The manuals are available at www.hp.com/networking/support.

■ Connecting the transceivers to Devices with Fixed Configurations. For some older network devices, including some older HP devices, the default for Gigabit-SX, Gigabit-LX, and Gigabit-LH ports is a fixed configuration (for example 1000 Mbps/Full Duplex) or may be otherwise different from the default transceiver configurations (which is Auto). As a result, devices may not connect properly to your transceiver port and you will not get a valid link. Because of these default configuration and full-duplex considerations, for best operation, you should make sure that the devices connected to the transceiver ports are also configured to Auto. At a minimum, make sure the configurations match.

■ Environmental requirement. When selecting an SFP, make sure it can function at a temperature that is not less than the recommended maximum operational temperature of the switch.

HP 2920 Switch Safety and Regulatory Information

To avoid personal injury or product damage when installing your HP 2920 Switch, read the installation precautions and guidelines below.

For additional Safety and Regulatory information, refer to the safety and regulatory documentation included with your2920 Switch, and to the safety and regulatory documentation on the HP web site at www.hp.com/support/Safety-Compliance-EnterpriseProducts, and to the switch Installation and Getting Started Guide that is located on the HP Networking web site: www.hp.com/networking/support.

Installation Precautions

Warnings

■ Do not mount the 2920 Switches on a wall.

■ Do not carry the 2920 Switches by using the handles of any installed power supplies.

■ The rack or cabinet should be adequately secured to prevent it from becoming unstable, tilting or falling.

■ Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices at

the bottom and progressively lighter devices above.

Cautions

■ Ensure the power source circuits are properly grounded, then use the power cord supplied with the switch to connect to the AC power source.

■ If your installation requires a different power cord than the one supplied with the switch and/or power supply, be sure the cord is adequately sized for the switch’s current requirements. In addition, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country/region. The mark is your assurance that the power cord can be used safely with the switch and power supply.

■ When installing the switch, the AC outlet should be near the switch and should be easily accessible in case the switch must be powered off.

■ Ensure the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the AC power connectors.

■ Do not install the switch in an environment where the operating ambient temperature exceeds its specification.

■ Ensure the air flow around the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling. For the air flow direction, see the switch Installation and Getting Started Guide, located on the HP Networking web site at www.hp.com/networking/support.
