Cabling the Service Processor

Connect a customer-supplied Ethernet cable to the lowest port on the server. Connect the power

cable to PDU, but do not power on at this point.

WARNING! Do not power on the service processor.

The following icon is typical, but it can vary by server.

Cabling Power to the Storage System

WARNING! Before you begin cabling the power cords, verify your power connections are set

up correctly. See “Verifying Power Connections” (page 54).

When routing PCM power cords, ensure power redundancy is maintained by connecting each

PCM within a shelf to a different PDU. When observed from the rear, the left side cabling (ID #0)

is black, and the right side cabling (ID #1) is gray.

WARNING! The PCM latch can damage any cables that are routed in such a way that when

the PCM latch handle is closed, it will cut into any cable that becomes wedged between the latch

and the rack post. Keep the cables clear from the PCM latch mechanism.

NOTE: When installing cabling, ensure clear access to all storage system components. All power

cords need to be tied and kept behind the rail column in order to access the components during

servicing.

To cable the power cables:

1. Locate the power cord for each PCM.

NOTE: Before inserting the power cords into the PCMs, verify the PCM power switch is set

to 0 (off).

2. Route the main power cords to a power strip or PDU. Ensure the routed cords maintain proper

service clearance.

3. Insert each end of the power cord into the power strip/PDU and PCM. Fasten the PCM power

cord using the restraining clip on each PCM.

NOTE: Do not power on the PCMs at this time.

Cabling the Power Distribution Unit

PDUs can be mounted horizontally below the enclosures at the bottom of the rack. Each PDU AC

cord connects to the appropriate outlet based on the type of cord and power requirements to

supply power to the storage system.

To access the vertically mounted PDUs or servicing area, the PDUs can be lowered out of the rack.

1. Remove the two top mounting screws.

2. Pull down on the PDU to lower.

NOTE: If necessary, loosen the two bottom screws to unhinge the bracket before pulling

down the PDU.
