DISPATCH INSTRUCTIONS

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

- TASK COMPLEXITY: 4

- TIME ESTIMATE: 150 minutes

FIELD ENGINEER INSTRUCTIONS

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

A data backup is not a pre-requisite but is a wise precaution
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 software system shutdown. Then power down the entire platform.
If this is a COD board a servicemode password should be obtained before the start of maintenance.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
The engineer should be M8000/M9000 trained

DELIVERY REQUIREMENT:
As scheduled

Estimated AP Duration: 2.5 hours

FIELD ENGINEER INSTRUCTIONS

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Active 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
   
   IO to the XSB must be quiesced to perform the next step.  See the DR Users Guide chapter 2 for more information.
3. Check for COD status using "showboards -va".
4. If the xsb contains an IOUA card the card will need to be deconfigured.
   
   XSCF> cfgdevice -l
   XSCF> cfgdevice -c detach -p port_no
5. Execute the deleteboard command to dynamically disconnect the CMU to be removed from all the affected domains.
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 the CMU
8. Transfer all components to the replacement CMU
9. Reinstall the 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.
11. If this is a COD board replacement change to servicemode and run "enablecodboard <cmu#>"
    example
    service> enablecodboard 1
     
12. Execute the addboard command to dynamically connect the IOU to all the affected domains

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
3. Execute the poweroff -d command to shut down the affected domains
4. 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
5. Remove the CMU
6. Transfer all components to the replacement CMU
7. Reinstall the CMU
8. 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
9. If this is a COD board replacement change to servicemode and run "enablecodboard <cmu#>"
   example
   service> enablecodboard 1
10. 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.

1. Switch off all main line switches for the AC section (ACS) in the power supply system.
2. Remove the CMU
3. Transfer all components to the replacement CMU
4. Reinstall the CMU
   
   
   Note: On a M9000 with an expansion cabinet the expansion cabinet should be switched on first then the base cabinet.

1. Switch on all main line switches for the AC section (ACS) in the power supply system.
2. Confirm that the XSCF STANDBY LED (green) on the operator panel remains lit. If it is blinking, wait until it remains lit.
3. If this is a COD board replacement change to servicemode and run "enablecodboard <cmu#>"
   example
   service> enablecodboard 1
    
4. Start (turn on power) all domains together

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
