Chapter 1 Install the Shelf and Backplane Cable
NTP-A13 Perform the Shelf Installation Acceptance Test
DLP-A32 Inspect the Shelf Installation and Connections
Step 1 Check each wire and cable connection to make sure all cables are locked securely. If a wire or cable is
loose, return to the appropriate procedure in this chapter to correct it.
Step 2 To check that the backplane is seated correctly, verify that the screw holes and the backplane interface
card holes align properly and that the A and B connectors interlock.
Step 3 Return to your originating procedure (NTP).
DLP-A33 Measure Voltage
Step 1 Using a voltmeter, verify the office ground and power. (Figure 1-10 on page 1-27 shows the power
terminals.)
a. Place the black lead (positive) on the frame ground on the bay. Hold it there while completing Step b.
b. Place the red lead (negative) on the fuse power points and alarm panel to verify that they read
between –42 VDC and –57 VDC (power) or 0 (return ground).
Step 2 Using a voltmeter, verify the shelf ground and power wiring:
a. Place the black lead (positive) on the RET1 and the red lead on the BAT1 point. Verify a reading
between –42 VDC and –57 VDC. If there is no voltage, check the following and correct if necessary:
• Battery and ground are reversed to the shelf.
• Battery is open or missing.
• Return is open or missing.
b. Repeat Step 2 for the RET2 and BAT2 if the B power feed is provided
Step 3 Return to your originating procedure (NTP).
Purpose Use this task to inspect the shelf installation and connections and to verify
that everything is installed and connected properly.
