FIELD ENGINEER INSTRUCTIONS
WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
Customer should conduct an orderly software system shutdown, power down system and disconnect Power Cord.
WHAT ACTION DOES ENGINEER NEED TO TAKE:
Cold replacement procedure is as follows:
1. Change operator panel from Locked to Service.
2. Ensure customer has powered down domains.
3. Confirm POWER LED (green) on the operator panel is off.
Note: On M9000-64, base cabinet should be switched off first.
4. Switch off all main line switches.
Caution - If dual power feed option is installed, switch off main line switches for both power supply units.
Caution - After stopping all domains, be sure to switch off main line switches in power supply system to completely shut off supply of power.
5. Connect wrist strap clip to a grounding port, and band to your wrist.
6. Remove following components so that you can access the PSU BP to be replaced.
    a. Remove all PSUs.
    b. Return fixing brackets of PSU at their original locations, and secure them with screws temporarily.
    c. Loosen thumb screws on PSU shelf.
   M8000 - While grasping the handle on the lower right side of the PSU shelf, pull the shelf out carefully.
    M9000 - While grasping handle at upper part of PSU shelf, pull shelf out carefully.
7. Remove PSU backplane (PSUBP) to be replaced.
   a. Loosen 2 thumb screws in PSU BP.
    b. Pull out PSUBP carefully.
8. Place removed BP on an antistatic conductive mat.
9. Mount replacement BP by following the removal instructions in Step 6 and Step 7 in reverse order. Align holes by the side of the thumb screws of the PSUBP with two guide pins in cabinet.
Caution - Be sure not to hit connector parts of the BP against anything.
Note: On a M9000-64 expansion cabinet should be switched on first.
10. Switch on all main line switches.
11. Confirm that XSCF STANDBY LED (green) on operator panel remains lit. If it is blinking, wait until it remains lit.
12. Using the XSCF command showhardconf and showstatus, confirm that each replacement component is normal.
13. Start all domains. Take either of the following two actions:
Press and hold down (for less than four seconds) the POWER switch on operator panel.
From a console that is connected to XSCF, execute poweron -a command of XSCF.
Power to all domains is applied, and (POST) is executed. When ok prompt is displayed on console of relevant domain, POST is completed.
14. Restore the original mode switch setting on operator panel.

OBTAIN CUSTOMER ACCEPTANCE
