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.

2. Wrap the label around the cable until it fully encircles the cable. The bottom of each label is clear so that it does not obscure
the text.

3. Apply a matching label to the other end of the cable.
Removing an Expansion Enclosure from a Chain Currently in Service
To remove an expansion enclosure, you disconnect the expansion enclosure from one side of the chain at a time.
About this task
During this process, one side of the chain is disconnected. The Storage Center directs all I/O to the other side of the chain, which
remains connected.
