wiring as shown in Figure 2-30. Each pin monitors a specific function and activates a specific
alarm.

Connecting to Power
Routers in the NV8500 family use power supply modules to power the router frames. The NV8144
uses the PS8100 modules (850
Watts each), which are inserted directly in to the router frame. The
NV8280/NV8280-Plus and NV8576/NV8576-Plus routers use Miranda’s NV8000 power supply,
an external frame that holds up to four PS8100 power supply modules (850
Watts each). Each
NV8000 holds up to two primary power supply modules and two redundant power supply modules.
