Replace a Replication Engine Power Distribution Board

The power distribution board (PDB) connects the two power supplies and the motherboard and distributes power by acting like a circuit breaker. A failed PDB is a critical point of failure and can affect the normal operation of the power supplies. Failed PDBs might bring down the Replication Engine and must be replaced as soon as possible.

Caution

Ensure that all power is removed from the Replication Engine before removing or installing the PDB. Also, disconnect the power cables before performing the motherboard removal procedure during PDB replacement.

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.
Ensure that there is a workbench available to place the Replication Engine chassis once it is removed from the rack for servicing.
Make sure that you have a Torx Number 10 screwdriver.

Each Replication Engine has a PDB that is located behind the power supplies, under the PDB signal cable. The PDB assembly is a field replaceable unit (FRU). Replacing a PDB is not a hot-serviceable process and requires you to power off the Replication Engine. The following figure shows the PDB assembly inside the Replication Engine.

Note: The PDB can be accessed only after removing the cover over the Replication Engine chassis.

Note: Since Replication Engine PDB replacement can take approximately an hour to complete and involves removing all CRUs and FRUs, Oracle Customer Support recommends that the Replication Engine be placed on a workbench for servicing rather than inside the rack for convenience.

Note: Replacement of the PDB requires assistance from Oracle Customer Support.
