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.

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.
CUID cable: Cables that connect the Replication Engine identification display (CUID) to the motherboard and supplies power and signal to the CUID.
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.
