4.7.2 Checking Battery Voltage at PDP
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 PDP and that the battery power is on.
The test equipment required is a DMM.
1 Set the DMM switches to measure voltage between 40 and 60 V DC.
2 On the front panel of the PDP, install all fuses.
3 Connect the negative DMM test lead to the first chassis ground 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 PDP. See Figure 4-9 [p. 4-21].
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. 4-24].
If NO:
Report trouble to the installation group. When trouble is corrected, repeat Step 3 [p. 4-24].
5 Disconnect the DMM leads.
6 Repeat Steps 3 [p. 4-24] through 5 [p. 4-24] for each applicable –48 V/GND pair.
7 On the PDP front panel, remove fuses A1-1 through B2-2.
This procedure is complete.
