Fibre Channel Drive Enclosures
The major enclosure components are:
■ 2.125-Gb, dual loop, 14-drive enclosure.
■ Dual-loop, FC-AL I/O modules and cable components that are the interface
between the drives and the host controllers.
■ Copper Fibre Channel cables
■ Fibre Channel disk drives and drive blanks.
■ Power and cooling components that include power supplies, cords, and
blowers.
■ EMU that monitors the operation of the enclosure and the elements while
displaying element status. When the EMU detects a condition that could

controller.

by the bay number. The drive in bay 1 is drive 1, the drive in bay 8 is drive 8. The
