DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

Field training in M10-4S servers

TASK COMPLEXITY: 4

Time Estimate: 90 minutes

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:All the power cords must be disconnected to completely cut the power to the server.

If there is any physical partitions in operation, the crossbar box cannot be powered off.

All physical partitions must be powered off, and the system must be completely shut down.

1. If the target Crossbar box is the master XSCF then switch the master role to standby.

XSCF> switchscf -t Standby

2. Verify the physical partitions ( PPAR ) status.

XSCF> showpcl -a -v

3. Power off the affected PPAR's.

Shutdown logical domains.

Shutdown the control domains.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing the Crossbar Unit

1. Run "showpparstatus -a" to verify the the ppars are powered off.

2. Execute the replacefru command to release the target crossbar unit from the system

3. Remove all power cords from the power supply unit of the target crossbar box

Note - To completely shut down the system, all the power cords must be disconnected. There is a risk of electrical failure if the power cords are not disconnected.

4, Move the mode switches to standby on both the master and the standby cabinet.

Note - Be sure to disconnect the crossbar cables (optical) after taking notes on the connection positions in order to reconnect the cables correctly.

5. Remove all optical crossbar cables connected to the target crossbar unit.

6. Loosen the two screws on the right and left sides and lower the levers to release the crossbar unit.

7. Support the crossbar unit from the bottom with one hand and remove it carefully.

Place the removed crossbar unit on a grounded antistatic ESD mat

Installing the Crossbar Unit

1. Carefully insert the crossbar unit into the cabinet.

2. Close the right and left levers of the crossbar unit and tighten two screws.

3. Connect all crossbar optical cables to the crossbar unit.

Note - Be sure to connect the crossbar cables (optical) to the original positions correctly according to the notes written down before maintenance.

4. Connect all power cords to the power supply unit of the target crossbar box.

Note - In a dual power feed, be sure to connect the power cord to the original position correctly according to the notes written down before maintenance.

5. Return to the operation of the XSCF firmware replacefru command to confirm that the crossbar unit is incorporated into the system.

6. Power on the target physical partition(s).

a.) Move the mode switches to locked on both the master and the standby cabinet.

b.) Execute the showstatus command to confirm that there is no problem with the FRU after the maintenance.

c.) Execute the showhardconf command to check the hardware configuration and the status of each component.

d.) Execute the switchscf -t Active command to switch the standby XSCF to the master XSCF.

e.) Execute the poweron - p <ppar_id> command to power on the stopped ppar.

f.) Review the "showlogs -V error" output to confirm there are no cable errors.

OBTAIN CUSTOMER ACCEPTANCE

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

Verify the staus of all domains.
