Avaya S8400 manual Administering the Snmp module, Security Alert

Configuration of the SNMP modules in the UPS

●If a Network Management System (NMS) is going to monitor the UPS, coordinate the assignment of community names with the network administrator.

If an NMS is not going to monitor the UPS, set the community names to unique string values.

!SECURITY ALERT:

The Get and Set, community name strings are initially 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 the defaults are left in place, they could result in a serious security issue.

See Setting selected traps (alarming) on page 28 for information on which traps to set.

●If the control network is nondedicated (going over the customer's network), make sure that the 162/udp port for input to server is enabled (the default is disabled). Otherwise, the media server cannot receive the traps from the UPS(s). See Enabling firewall settings on page 40.

Administering the SNMP module

Note:

Use the default addresses in the tables.

1.Connect the services laptop computer (RS-232 serial port) to the DB-9 connector on the back of the SNMP module for UPS1 using the DB-9 to DB-9 serial cable supplied with the SNMP module.

2.Open a VT-100 terminal emulation session on the services laptop.

3.Set the IP address for the UPS.

4.Set the subnet mask for the UPS.

5.Set the gateway address for the UPS.

6.Set the IP address of the trap receiver (media server) for the UPS.

7.Set the SNMP community name string for Get, Set, and Trap. See Setting selected traps (alarming) on page 28 for information on which traps to set.

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

9.Connect one end of a CAT5 straight-through cable to the RJ45 connector on the UPS SNMP module and the other end to the next available port on the Ethernet switch for Control Network A (CNA).
