RAID Cable Restrictions

RAID Host Adapters use a SCSI cable that connects each Disk Expansion Unit to its RAID Host Adapter in the Basic System Unit. Cables are available in 3.3-ft (1m) and 9.9-ft (3m) lengths.

Concentrator Cable Lengths

Cables for concentrator connections are available in 7-ft (2.1m) and 12-ft (3.7m) lengths.

To accommodate the installation of the keyboard, mouse, and monitor on an external desktop, a 12-ft (3.7m) extension cable that allows you to achieve an overall cable length of 19-ft (5.8m) or 23-ft (7.3m) is available.

NOTE: Extension cables should only be used between the keyboard, mouse, and monitor and the concentrator. They cannot be used between the concentrator and a BSU.

Vertical Spacing

Vertical measurements of rack components are given in Us. 1U is equal to 1.75 inches.

The total usable vertical space within a 42U rack is 42Us or 73.5 inches.

Figure 3-1 illustrates the arrangement of rack mounting holes and their relationship to a U.
