Cabling the enclosure

After installing the enclosure in a rack, connect the SAS cables and power cords to the rear panel.

SAS cabling guidelines

Observe the following guidelines:
• Only use supported SAS cables with 3-GB connectors.
• Ensure that the servers attached to the enclosure are powered down and power cords are
disconnected before connecting SAS cables.

Supported cables

possible, however, other supported cable lengths between SAS ports are 2 m (6.56 ft), 4 m (13.12 ft), and
6 m (19.69 ft). To acquire different lengths, contact the nearest authorized HP reseller.
