6.4 Replacing DPU Power Trays

6.4 Replacing DPU Power Trays

This section contains instructions for removing and installing the DPU power
trays.

6.4.1 Removing the DECmpp 12000/Sx Power Tray

Caution

It is important to label all cables as you disconnect them. Reinstalling
cables with the wrong polarity can render the system inoperative.

Follow these steps to remove the power tray:

1.

Shut down the server and turn off the power to the server and the DPU.

2.

Open the back door of the DPU.

3.

Set the DPU 30 A circuit breaker OFF, and unplug the power cord from the
power source.

4.

To avoid possible problems when powering up, use the ejector levers shown
in Figure 6–4 to remove each PCB from the backplane, in both the upper and
lower card cages.

5.

Disconnect all the cables at the back of the power tray (Figure 6–6).

6.

Open the DPU front door. Figure 6–7 shows a front view of the power tray.

7.

Using two 9/16-inch open-end wrenches, remove the +5 V positive and
negative power bars at the front of the power tray. Note the offset on the
negative post for reinstallation. This offset is needed for clearance between
the positive and negative posts.

To avoid damage to the power post on the –12 V supply, do not use a deep
socket when removing the po5 V bar.

8.

Using a 9/16-inch wrench, remove the cables from the –5 V supply.

9.

Using a 5/16-inch wrench, remove the +12 V and –12 V cables.

10. Cut any cable restraints fastening cables to the power tray.

11. Remove four screws in the front and two screws in the rear that secure the

power tray to the enclosure frame and air plenum.

12. Make sure you have disconnected all cables from the back of the power tray.

Do not let the power cables get caught on the power tray while sliding it out
or in. Cuts in cable insulation can cause direct shorts.

13. From the DPU front, gently slide the power tray forward, checking that no

cables are getting caught on the power tray. Make sure the attached AC
power cord does not get caught coming through the rear skirt assembly. Also,
make sure that the gasket on the fan tray above does not get caught and tear
away.

14. Do not place any weight on the back of the power tray.
