Cheetah 36LP FC Product Manual, Rev. C

9.5.11.1

Parallel Enclosure Services Interface (ESI)

The parallel ESI line is an output from the drive. This line provides the enclosure with an indication of the
present function of the SEL lines. A high level, the default state, indicates the drive requires address informa-
tion on the SEL lines. A low level indicates the drive is attempting an ESI transfer. The enclosure may not sup-
port ESI on any or all drive locations. It may only support the address function. Support of ESI is discovered by
the drive. Refer to the Fibre Channel Interface Manual for a description of ESI operations.
