Label the Back-End Cables

Label the back-end cables that interconnect the storage controllers or label the back-end cables that connect the storage system

to the expansion enclosures.

Prerequisites

Locate the cable labels provided with the expansion enclosures.

About this task

Apply cable labels to both ends of each SAS cable to indicate the chain number and side (A or B).

Steps

1. Starting with the top edge of the label, attach the label to the cable near the connector.
