DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: Mx000 training and basic field engineer skills

TASK COMPLEXITY: 2

TIME ESTIMATE: 150 minutes

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

Note !! If 143527-01 is not installed on the domain perform the following steps:
Immediately before shutting down the domain use fmadm to clear the fault on the domain.
# fmadm repair <uuid>

For an active replacement the customer is not required to perform a system shutdown
For a hot replacement the customer is required to perform a domain(s) shutdown
For a cold replacement the customer should conduct an orderly system software shutdown. Then power down the entire platform.

FIELD ENGINEER INSTRUCTIONS
Review and follow Document 1021062.1 while working with removed CMU.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Active & Hot Replacement
1. Connect to serial port of the active XSCF to ensure that communication will not be lost.
2. Execute showfru, showdcl, showboards to identify the affected domains

Active Replacement (Only )

NOTE: IO to the XSB must be quiesced to perform the next step. See the DR Users Guide chapter 2 for more information.

3. If the xsb contains an IOUA card the card will need to be deconfigured.
    XSCF> cfgdevice -l
    XSCF> cfgdevice -c detach -p port_no
4. Execute the deleteboard command to disconnect the CMU from all the affected domains.

Hot Replacement (Only )
5. Execute the poweroff -d command to shut down the affected domains

Active & Hot Replacement
6. Execute the replacefru command.
    On the maintenance menu, select 1, "CMU/IOU."
    From here, perform the operation according to the guidance displayed in the maintenance menu
7. Remove CMU
8. Replace DIMM
9. Reinstall CMU
10. Continue to follow the instructions from the maintenance menu. When the display of the maintenance menu returns to the initial page exit the maintenance menu

Active Replacement (Only )
11. Execute addboard command to connect the CMU/IOU to all the affected domains
Hot Replacement (Only )
12. Execute the poweron -d command to power on the affected domains

Cold Replacement
1. Customer should perform an orderly shutdown of the domains.
2. Change the mode switch setting on the operator panel from Locked to Service.
3. From a console that is connected to XSCF, log in to XSCF, and execute the poweroff -a command.
4. Confirm that the power-off processing is completed by confirming that the POWER LED (green) on the operator panel is off.

Note: On a M9000 with an expansion cabinet the base cabinet should be switched off first then the expansion cabinet.

5. Switch off all main line switches for the AC section (ACS) in the power supply system.
6. Remove the CMU
7. Replace DIMM.
8. Reinstall the CMU

Note: On a M9000 with an expansion cabinet the expansion cabinet should be switched on first then the base cabinet.

9. Switch on all main line switches for the AC section (ACS) in the power supply system.
10. Confirm that the XSCF STANDBY LED (green) on the operator panel remains lit. If it is blinking, wait until it remains lit.
11. Start (turn on power) all domains together

When the maintenance work is completed, be sure to confirm the mode switch setting and return the switch to Locked.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Check full functionality has been retained

Confirm hardware by running the following commands:
XSCF> showhardconf -M
XSCF> showstatus

PARTS NOTE:

None
