Cabling

This chapter describes the cabling between the controller enclosure, the front-end host,
and the expansion enclosures. It also covers Ethernet, serial port, and power connections
in the following sections:
• "Connecting the Drive Loop Cables" on page 65
• "Connecting the System to the Hosts" on page 69
• "Powering On the System" on page 75
The system is designed to support redundant drive loops. A redundant drive loop
consists of one or more expansion enclosures connected to the controller enclosure using
two sets of data cables. If one data path fails, the controller uses the other data path to
maintain access to the drive group.
Follow these instructions to cable a group of enclosures into a redundant drive loop. If
the drive loop contains only one enclosure, skip this procedure and proceed to
"Connecting the System to the Hosts" on page 69.
Warning:
Electrostatic discharge can damage sensitive components. Use
appropriate antistatic precautions before handling any components.
To complete this procedure, you will need two optic interface cables.
