Configure The Upss - Avaya S8700 Installing Manual

Configure the UPSs

The following procedure is specific to the Powerware 9125 equipped with a ConnectUPS™
SNMP Module. If a different UPS is used, refer to its accompanying documentation to set the IP
Address/Subnet mask, trap receiver IP address, and community strings.
The SNMP module in the UPS must be administered so it can report alarm conditions to the
appropriate media server when the hardware experiences problems. The module reports the loss
of commercial power and/or the depletion of battery resources.
!
WARNING:
It is critical that each UPS report SNMP traps to the server it is powering. For example,
server 1 should be plugged into UPS 1 and UPS 1 must be configured to report SNMP
traps to the server 1 IP address (not the 'Active Server' address). The same required
relationship holds true for server 2 and UPS 2. This is important because if the UPS
detects loss of commercial power and/or depletion of battery resources it will send a trap
to allow the server to gracefully shutdown. If the UPS sends the trap to the wrong server
trap receiver address, that server will shutdown while the server that is plugged into the
UPS will fail due to loss of power.
Each UPS requires a unique IP address, which can be a customer-provided one or the
Avaya-provided default one. Refer to the filled-out Job Aid entitled Pre-Installation Network
Planning Form—S8700 Media Server:
• 2 IP addresses (1 for each UPS)
• 1 Default gateway IP address
Subnet mask
•
• Community name strings (get, set, trap)
NOTE:
For the UPS to properly report alarm conditions, the IP addresses for the UPS must be
configured in the S8700 Media Servers.
SECURITY ALERT
The Get and Set, community name strings are generally configured with default values of
Public and Private, respectively. These community name strings function as passwords for
their respective SNMP operation. It is always a good idea to change these community name
strings to something other than the default values. If a Network Management Station is in
operation on the network, whatever these values are changed to must be coordinated with its
administrator. If the defaults are left administered this could create a serious security issue. For
example, the default Set community name string, with it's widely known value of Private, could
be used to shutdown power to the UPS loads via SNMP message.
Refer to the configuration section of the user guide that comes with the SNMP module for the
default user ID and password and the administration commands. Use the following general
procedures to administer the SNMP modules:
