Replacing a ZS4-4 DIMM
Caution - A CPU is a field replaceable unit (FRU) and must be replaced by a trained Oracle
service technician.
Replacing a ZS4-4 DIMM
Use the following procedure to replace a ZS4-4 DIMM.
1.
Shut down the controller using one of the power-off methods described in
“Powering Off the Controller” on page 50.
2.
Disconnect the AC power cords from the rear panel of the storage controller.
Caution - Because 3.3 VDC standby power is always present in the system, you must unplug
the power cords before accessing any cold-serviceable components.
3.
Extend the controller from the rack as described in “Extending the Storage
Controller from the Rack” on page 51.
4.
Remove the top cover as described in “Removing the Top Cover” on page 52.
5.
Remove the memory riser card with the lighted Fault indicators (P0/MR0
and P0/MR1), and locate the failed DIMM. Use the DIMM Fault Remind
circuit to locate the failed DIMM. See “Identifying a Faulted ZS4-4 Memory
Module” on page 60.
