How to remove and replace a PSU in an External I/O Expansion Unit

Solution

DISPATCH INSTRUCTIONS
    - WHAT SKILLS DOES THE ENGINEER NEED:
       Engineer has to complete the host system's (Mx000/T5xxx) training.

    - TIME ESTIMATE: 30 minutes

    - TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
    - PROBLEM OVERVIEW
       How to remove and replace a PSU in an External I/O Expansion Unit

    - WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
    RESOLUTION ACTIVITY?
       This is a hot replacement procedure, meaning that the PSU can be replaced while the system is still running, provided that a second PSU is working properly.

    - WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
1. Use an antistatic strap for this procedure.

2. Unpack the new power supply unit and set it flat on an antistatic surface.
    Make sure the AC switch on the new PSU is in the "OFF" position.
    CAUTION! Do not rest a PSU vertically. The plastic electrical connector on the back is breakable.

If the system is connected to a SPARC Enterprise Mx000 Server
  2a. If the system is running, power down the PSU (x) in the affected Expansion Unit (nnnn) with the ioxadm command:
        XSCF> ioxadm poweroff iox@nnnn/psx
        Refer to the ioxadm (8) man page for more information.

3. At the front of the defective PSU, turn off the PSU AC switch and verify that the DC Power LED turns off.

4. Loosen the handle locking screw on the PSU handle.

5. Unlock the PSU by swinging the handle out 90 degrees into the fully open position.

6. Place a hand under the PSU to prevent it from falling, then pull the PSU out of the External I/O Expansion Unit.
   CAUTION! The PSU is heavy (7.5 lb/3.4 kg).
   When you can see the warning label on the top of the PSU, the PSU is almost fully out of the PSU slot.
   CAUTION! Do not allow the rear of the PSU to drop. The connector at the rear of the PSU can be damaged if it strikes the edge of the slot.
   A pivoting flap behind the PSU drops down to prevent loss of cooling air.

7. Set the PSU flat on an antistatic surface.

8. Insert the new PSU into the External I/O Expansion Unit.
   The pivoting flap automatically swings up and out of the way.
   NOTE: The fan in the new PSU turns on immediately if the External I/O Expansion Unit is running.

9. Turn the PSU handle 90 degrees into the closed position.

10. Secure the handle locking screw on the PSU handle.

11. Turn on the AC switch on the PSU.
    The Fault/Locate LED on the PSU lights up momentarily during the initialization then turns off. You should see the AC power and DC power LEDs turn on after the initialization.

OBTAIN CUSTOMER ACCEPTANCE
    - WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
    AN OPERATIONAL STATE:
      On an Mx000 the customer can check the status of the new PSx in the affect Expansion Unit (nnnn) through the XSCF's CLI:

XSCF> ioxadm list iox@nnnn/psx
Refer to the ioxadm (8) man page for more information.

      On a T5xxx the customer can check the status of the new PSx in the affect Expansion Unit (nnnn) through the ILOM CLI:

-> cd IOX@nnnn

-> show -display all /SYS/IOX@nnnn/PSx

PARTS NOTE:
300-1701 A195 Power Supply
