1.1.1 Network-dedicated solution: Solution-Pac / WAN

◗ Protection of your IT equipment by managing their shutdown in the event of an extended powerfailure,

◗ Notification of power quality events affecting your protected IT equipment,◗ Supervision of any UPS system connected to your IT network.

The components of the Solution-Pac / WAN suite include:◗ The SNMP agent (SNMP/Web Card or UM-Agent software): supervises the UPS, informs the UM-

Client of events occurring on the UPS by SNMP traps and manages UPS shutdowns and restarts.◗ UM-Client protects the workstation on which it is installed and informs administrators and users of

major events by network notification, e-mail, SMS or fax (with the Jericho alarm module underWindows).

◗ UM-Console (+) supervises and configures the SNMP agent and the UM-Client of the workstationon which it is installed.

◗ UM-Editor configures UM-Client and UM-Agent

The software components for each platform and the user manuals are supplied free-of-charge on theSolution-Pac CD or are available for download on the www.mgeups.com Web site, in the “Downloadarea” section.

4 Supervision / Administration via SNMP

4.1 SNMP offer operation principle

UM-Client, on protected server boot, subscribes itself automatically to the SNMP agent (in themanager table) and sends the essential data:◗ IP address of the server on which it is installed, to be notified by the SNMP agent of any power

events (SNMP traps).◗ Time required to shutdown the server (UM-Client Shutdown Duration, configurable with the UM-

Editor utility, installed with UM-Client):The SNMP agent takes into account the longest shutdown time of all UM-Clients subscribed (whichis the Shutdown Duration of the SNMP agent) to manage UPS shutdown without affecting any ofthe connected UM-Clients.

In case of a major power event, UM Client receives the traps (SNMP messages) from the SNMP agentand regularly checks agent accessibility. The most important messages can generate actions and aresent back to the administrator and users via the network.When the server shuts down, UM-Client unsubscribes itself from the manager table (the “Protocol”field changes to “invalid”).

4.1.1 Shutdown criteria

During an extended power failure, three criteria may cause the server shutdown procedure to beinitiated. If several criteria are selected, the first criterion encountered will launch the shutdownprocedure.At the end of the shutdown procedure, when all servers have been shut down, the UPS may shutdown to avoid unnecessary discharge of its batteries, depending on its configuration.

4.1.1.1 Backup time before initiating the shutdown procedure (Shutdown timer)

When the UPS switches to battery, the SNMP agent starts the Shutdown Timer countdown andlaunches the system shutdown procedure at the end of the countdown.This value must be chosen so that users have time to complete their tasks and disconnect, withoutexceeding battery backup time.By default, this value is set to 30 minutes.Configuration with UM-Console(+), UM-Vision or SET SNMP

Note 1:UM-Client also manages its own Shutdown Timer (configurable with UM-Editor), triggered by receptionof the SNMP trap “Mains loss”.Note that if this criterion is selected to initiate system shutdown, automatic system reboot when poweris restored is not guaranteed (e.g. power restoration if only this system was shut down). Werecommend leaving this parameter at a value greater than the one of the Shutdown Timer of theSNMP agent.By default, this value is set to 31 minutes.

Note 2:For devices without UM-Clients (backup units, routers and other internetworking equipment,automated systems, etc.), in the case of extended backup time, the SNMP agent will launch a UPSshutdown at the end of the Shutdown Timer. To avoid this behavior, a Shutdown Timer value longerthan the maximum installation backup time must be programmed.

www.mgeups.com



4.1.1.2 Initiating the shutdown procedure when the battery level is lower than: (Low BatteryLevel)

When the SNMP agent detects that the remaining backup time percentage is less than the configuredlevel, the shutdown sequence is started.By default, this value is set in the UPS.

Note:Certain types of UPS only accept pre-defined minimum battery level values (e.g. : 20% or 40% forCOMET and PULSAR EXtreme). Check the UPS documentation.

4.1.1.3 Shutdown when backup time is less than

When the SNMP agent detects that the percentage of backup time remaining is less than the valueset, the shutdown sequence is started.

4.1.1.4 Shutdown duration

Duration required for the systems protected by UM-Client to shut down (in seconds).

4.1.2 Individual outlet control

Some UPS models are equipped with outlets or group of outlets (typically 2), that can be controlled orprogrammed individually (while still remaining dependent on the main UPS control). MGE name forthis feature is PowerShare.Shutdown of the UPS systematically causes shutdown of the controlable outlets.

Depending on the UPS range, the following notation is used to mark these outlets:◗ Main outlet: Main or 1◗ Programmable outlet 1 1 or 2◗ Programmable outlet 2 2 or 3

4.1.3 Connecting a server protected by UM-Client to a controlled outlet

After connecting the server electrically to one of the controlled outlets, UM-Client must be informed ofthe outlet number to which it is connected.Start UM-Editor (installed with Solution-Pac / WAN), select the “Switchable plug” box and specify theoutlet number (1=main, 2 or 3) in the “Receptacle Number” field.

www.mgeups.com



4.1.3.1 Load shedding or sequential shutdown

It is possible to optimise backup time by shutting down non-priority equipment or sequencing theshutdown of several devices.Two shutdown criteria are possible:1. Shutdown of outlets after a set battery back-up time (ShutOff Delay, programmable in UM-

Console, UM-Vision)2. Shutdown of outlets at a given battery discharge level (ShutOff Level, programmable in UM-

Vision)It is possible to specify values for both criteria. The first criterion reached will initiate server shutdown.

4.1.3.2 Sequential startup

It is possible to delay outlet power-on to reduce inrush currents on startup or to sequence the startupof several devices.Outlet startup after a given time is based on startup of the main outlet (Restart delay, programmable inUM-Console, UM-Vision)

www.mgeups.com



4.2 The different server and UPS shutdown sequences

4.2.1 Extended power outage, shutdown initiated by the Shutdown Timer

During battery backup time, the Shutdown Timer of the SNMP agent is reached: after a user-definedbackup time period (UM-Console +, UM Vision), shutdown of all servers is initiated, followed by theUPS shutdown (depending on its configuration). The UPS restarts when utility power is restored(depending on its configuration).◗ Shutdown Duration: Maximum value of shutdown times of the UM-Clients subscribed to the card

and depending on the main UPS outlet. This value is updated each time a client subscribes/unsubscribes.

◗ Shutdown Duration 1 (2): Maximum value of shutdown times of the UM-Client subscribed to thecard and dependent on outlet 1 (2). This value is updated each time a UM-Client dependent onoutlet 1 (2) subscribes /unsubscribes.

Note: During battery operation, these values are not updated.

4.2.1.1 Main UPS outlet

MD5Message Digest 5. Algorithm producing an output message from an input message of arbitrary length,in the form of a replica or summary 128 bit message. Intended for digital signature applicationsrequiring large files to be compressed in total security before being coded with a private key, using apublic key algorithm, like RSA.

MIB MANAGEMENT INFORMATION BASE- Group of software commands to control and administrate a device through the network. Each type ofdevice (server, hub, PC, UPS, etc.) has its own MIB– The IETF has proposed a standard MIB for each group of devices (hubs, for example) to simplifyadministration if they come from different suppliers

Programmable outlet (controlled outlet):Outlet that can be remote-switched on or off. In Solution-Pac / WAN, the UM-Console+ or UM-Clientcomponents enable management of such outlets.

REBOOT –To restart a system after an interruption.– To perform an obstacle-free “reboot”, it is essential that the system is correctly and carefully shutdown beforehand.– The reboot is usually automatic if the computer is re-supplied with electricity (from the mains or fromthe UPS).

RFCRequest for Comments. All documents defining internal Internet operation.

SNMP (SIMPLE NETWORK MANAGEMENT PROTOCOL)Protocol used to remote-supervise, administrate and control devices connected to a company network.

SNMP agent:Name of a device used to communicate data from one system (like a UPS) over a network. (SNMP/Web Card or the UM-Agent software): supervises the UPS, informs the UM-Clients of eventsoccurring on the UPS by means of SNMP traps and manages UPS shutdowns and restarts

Subnet mask:Mask of bits used to identify and differentiate the network address and the equipment address in an IPaddress.Normally, the mask is automatically determined by the class of address, which defines in a uniquemanner the network part/equipment part division of the IP address.- Class A: internet address: 255.0.0.0.- Class B: internet address: 255.255.0.0.- Class C: internet address: 255.255.255.0.

TCP/IPTransmission Control Protocol/Internet Protocol. Common name of a series of protocols developed bythe DOD in the US to help build Internet networks throughout the world.

TelnetInternet protocol used for terminal emulation, i.e. enabling a computer to connect with a server as if itwas a simple terminal locally connected to this server.

Trap (SNMP)This term describes an event that affects an MIB variable. Traps are sent to the manager, which isprogrammed to perform specific tasks upon reception of the traps.

UM-ClientUM-Client is a software package (SNMP manager) that uses the information sent by the agentdedicated to the MGE UPS in order to inform users of the computer of the power quality status.In case of a power failure, UM-Client triggers a graceful shutdown procedure at the end of a presetbattery runtime.
