2.7.2 Checking Battery Voltage at Circuit Breaker Panel
Note: In this procedure, the term battery refers to the DC power feed for the rack in which the
equipment is being mounted.
Note: This procedure assumes that power cables have been connected between the office battery and
the CBP and that the battery power is on.
The test equipment required is a DMM (digital multimeter).
1 Set the DMM switches to measure voltage between 40 and 60 V DC.
2 On the front panel of the CBP, set all circuit breakers to the ON position.
3 Connect the negative DMM test lead to the first GND connector on the front panel, and
connect the positive DMM test lead to the associated input voltage test point (–48 V) on the
front of the CBP. See Figure 2-12 [p. 2-22].
The input voltage should be between –40 and –57 V DC.
4 Is the DMM measurement between –40 and –57 V DC?
If YES:
Continue with Step 5 [p. 2-24].
If NO:
Report trouble to the installation group. When trouble is corrected, repeat Step 3 [p. 2-24].
5 Disconnect the DMM leads.
6 Repeat Steps 3 [p. 2-24] through 5 [p. 2-24] for each applicable –48 V/GND pair.
7 On the CBP front panel, set all circuit breakers to the OFF position.
This procedure is complete.
