These alarms then should be tested using the
test eda-external-device-alarm all
command. When the
equipment room AC breaker for the GMCC is shut off, this 01minor (AC) test will fail.
Hooking up sensor cable and batteries
When using large battery holdover, 1 battery cabinet is
required for every MCC1 Media Gateway requiring holdover. The 24-cell battery cabinet must have a
float voltage of 54.2 VDC.
1
Connect the -48 VDC cable to the large battery connector. See
Figure 31, Power distribution unit
(J58890CH),
on page 113.
2
Connect the -48 VDC RETURN cable to the ground terminal block. This is a positive ground
system where the +48 V battery lead is called -48 VDC RETURN and it will be connected to the
cabinet frame ground.
3
Connect the temperature sensor cable, from the battery cabinet, to J20.
