The disk backplane provides a physical interconnect for the drives. The disk backplane, if damaged, prevents the drives from seating properly. Improper seating prevents the modules from providing backup power to flash memory, which can lead to data loss.
- Prerequisites:
Ensure that you have a Phillips Number 2 screwdriver with at least a 4-inch shaft.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Remove the drives from the drive compartment and make a note of the drive slots so that they can be re-inserted after the replacement procedure.
Caution
Ensure that all power is removed from the Replication Engine before removing or installing the disk backplane. Disconnect the power cables before performing the disk backplane replacement procedure.Each Replication Engine has a disk backplane that is located at the back of the Replication Engine drive compartment. The disk backplane is a field replaceable unit (FRU). Replacing an disk backplane requires you to bring the Replication Engine offline. The following figure shows the disk backplane.

Note: The disk backplane can be accessed only after removing the cover over the Replication Engine chassis.
Note: To replace an disk backplane, you do not need to remove the Replication Engine from the rack but extend it along the Replication Engine rails using the cable management arm (CMA).
Note: The drive compartment must be disengaged and raised inside the Replication Engine chassis to perform many of the replacement procedures.
Caution
Replacement of the Replication Engine disk backplane requires assistance from Oracle Customer Support. Procedure Overview
