Replace Replication Engine Motherboard Cables

The motherboard cables provide power, switch, or signal connectivity to the various Replication Engine components. Damage to any of these cables might impact the normal operations of the Replication Engine and must be replaced as soon as possible.

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.

Each Replication Engine has five cable bundles that are routed throughout the chassis. The motherboard cables bundles are field replaceable units (FRUs). Replacing motherboard cables requires you to bring the Replication Engine offline. The five cable bundles included in the motherboard cable kit are as follows:
  • SAS cable: Cables connected to the Replication Engine backplane and a SAS connector on the motherboard.

  • USB cable: Cables that connect the Replication Engine USB ports.

  • LED board cable: Cables that connect the LED alarm assembly to the motherboard and supplies power and switch connectivity to the LED alarm assembly.

  • Drive signal cable: Cables that connect the motherboard and the drive cage and supplies power to the hard drives in the drive cage.

  • PDB signal cable: A flat cable that connects the power distribution board (PDB) to the motherboard and provides signal connectivity to the PDB.

The following figure identifies all the internal cables on the Replication Engine motherboard.

Note: The motherboard cables can be accessed only after removing the cover over the Replication Engine chassis.
Note: Because Replication Engine motherboard cable replacement can take some time to complete to identify the cables for replacement, the Replication Engine should be placed on a workbench for servicing rather than inside the rack for convenience.
Caution
Replacement of the Replication Engine motherboard cables requires assistance from Oracle Customer Support.
Caution
Ensure that all power is removed from the Replication Engine before removing or installing the motherboard. Disconnect the power cords before performing the motherboard replacement procedure.
