Configuring the SNMP modules in the uninterruptible power supplies
48
Installing the Avaya S8700 Media Server with an Avaya G650 Media Gateway
December 2003
Use the following general procedures to administer the SNMP modules:
1
Make sure the UPS is plugged into a nonswitched electrical outlet.
2
Connect the services laptop computer (RS-232 serial port) to the DB-9 connector on the back of
the SNMP module for UPS 1 using the DB-9 to DB-9 serial cable supplied with the SNMP
module.
NOTE:
Avaya Terminal Emulation and HyperTerminal are supported terminal emulation
applications. Terranova is not supported.
3
On the services laptop open a VT-100 terminal emulation session using an application such as
Avaya Native Configuration Manager.
4
Administer the terminal emulation port settings:
•
9600 baud
•
No parity
•
8 data bits
•
1 stop bit
•
No flow control
5
Follow the instructions in User’s Guide.
6
Set the following parameters:
•
IP address and subnet mask of the UPS
•
For UPS1, the defaults are 198.152.254.239, 255.255.255.0.
•
For UPS2, the defaults are 198.152.255.239, 255.255.255.0.
•
IP address of the trap receiver. (Do not use the Active Server IP address.)
•
For UPS1, this is the IP address of media server 1 (default is 198.152.254.200).
•
For UPS2, this is the IP address of media server 2 (default is 198.152.255.200).
•
Default Gateway address of the UPS is 198.152.254.201.
NOTE:
If a Network Management System (NMS) is going to monitor the UPS units, coordinate
the assignment of community names with the network administrator (see the filled-out
Electronic Preinstallation Worksheet). If an NMS is not going to monitor the UPSs, set the
community names to unique string values.
•
SNMP community string for Get, Set, and Trap.
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.

When completed, disconnect the services laptop computer from the UPS.
