FRU Removal and Replacement
Replacing a Power Module Assembly
To replace the power module assembly:
1. Remove the replacement power module assembly from its protective antistatic
bag.
2. Inspect the PWA side of the power module assembly for bent or broken connector
pins that may have been damaged during shipping. If any pins are damaged,
obtain a new assembly.
3. Position the power module assembly at the rear of the director chassis, as shown
in Figure 4–10. Push the module toward the backplane to engage the connector
pins. Support the fan module with one hand when performing this step.
4. Using a standard Phillips screwdriver, insert and tighten the six panhead Phillips
screws that secure the power module assembly.
5. Replace both SBAR assemblies (RRP: Redundant SBAR Assembly on page
4–20).
6. Replace the RFI shield.
7. Seat and connect both power supplies (RRP: Redundant Power Supply on page
4–17).
8. Disconnect the ESD wrist strap from the director chassis and your wrist.
9. Power on the director (Power-On Procedure on page 3–40).
10. Verify that power-on self-tests (POSTs) complete and the green power LED on the
front bezel, green LED on the active CTP2 card, and green PWR OK LEDs on
both power supplies remain illuminated. If a problem is indicated, go to MAP
0000: Start MAP on page 2–12 to isolate the problem.
11. At the HAFM server’s Hardware View, observe all FRU graphics and ensure no
alert symbols display that indicate a failure (yellow triangle or red diamond). If a
problem is indicated, go to MAP 0000: Start MAP on page 2–12 to isolate the
problem.
12. If necessary, close and lock the equipment cabinet doors.
13. Perform the data collection procedure (Collecting Maintenance Data on page
3–37).
