Alarms

Caution!

Increasing the threshold from this factory default setting may prevent the unit

generating an alarm during a fan failure or air-conditioning failure event.

4.4.6 PSU Alarms

The EQ8096 utilizes up to 2 Hot-swappable PSUs and supports PSU failure

detection for each PSU fitted.

When dual-redundant PSUs are fitted (option EQ8096/HWO/DPS), the power

supplies operate in a load-shared scheme. In the rare event of a PSU failure, the

remaining PSU will provide power to the unit. In this situation, an alarm will be raised

and the PSU unit should be replaced as soon as possible.

When the unit is operating with a single PSU, the Alarm status page will show this

as ‘not fitted’ as shown in Figure 4.8.

4.5 Trap Destination Table

Figure 4.9 shows the Trap (alarm) Destination web page. The Simple Network

Management Protocol (SNMP) Trap addresses are set here. Once the addresses of

the SNMP servers are entered, any alarms will be broadcast to all destinations. The

EQ8096 maintains a list of the last 20 reported alarms (traps) and makes it available

to the SNMP management system.
