Making Alarm Connections
Routers in the NV8500 family provide system alarms that notify you of a malfunction, such as
when a fan or power supply is not functioning properly. Alarms can be connected to an external
alarm indicator that displays visual cues when an alarm is activated. For the router frames that use
the NV8000 power supply frame also has alarm connections. Miranda does not provide external
indicator equipment, but does provide instructions on wiring the alarm connections. See Alarm
Indicator Equipment on page 84.
Both the router frames and the NV8000 power supply send status information to the router control
system. For more information on the alarm connections, see System Alarm
on page 36.
How to Make Alarm Connections for Routers
1 On the rear of the router, locate the ‘ALARMS’ connection, as shown in Figure 2-27.
