Remove a Slammer Private Interconnect Module
To help you identify the target control unit (CU) that has the
FRU that needs to be replaced, Guided Maintenance
beacons the bezel LEDs on the target CU. If you choose
Reverse Identify in the GUI, Guided Maintenance beacons all
LEDs except for the target CU.
After you click the Prepare System button in the GUI, Guided
Maintenance prepares the system for replacement of that
FRU. Guided Maintenance:
• Fails over the target control unit (CU) to its partner CU.
• Powers down the target CU.
After the system is prepared, Guided Maintenance displays a
completion message and enables the Next button.
To remove a private interconnect module:
1 After Guided Maintenance enables the Next button in the
Prepare step, click the Next button.
2 When Guided Maintenance prompts you, remove the
power cords from both power supplies of the target
control unit (CU).
Important!
Do not remove the power cords from the
partner CU. That CU supports all the user data paths for
this Slammer.
Important!
Before removing any cables, label them to
show which cable connects to which port on the private
interconnect module.
3 Disconnect all Ethernet cables from the ETH ports in the
target CU.
