Chapter 9: PowerNet MIB
Traps
This chapter describes the PowerNet MIB traps that a Management Card, PowerNet Agent,
MasterSwitch unit, or Automatic Transfer Switch can send to an NMS to alert the NMS that a specific
event has occurred and describes how to define which NMSs can receive those traps. (See How To
Define Trap Receivers.)
The PowerNet MIB 3.4.4 supports sending 175 APC enterprise-specific traps (numbered 1 through
176, with number 40 unused). The PowerNet MIB 2.2 supported only 32 traps.
No device can generate all 175 traps. For example, some traps report only events related to a
MasterSwitch unit, which has its own SNMP agent. Even if a device can send a trap, no NMS can
receive the trap until at least one of the four trap receiver definitions exists for the device. By default,
all Management Cards, Agents, MasterSwitch
units, and Automatic Transfer Switches have no trap
receivers defined. (See How To Define Trap Receivers.)
