2: The Controller Enclosure
GBIC Module
Interface Cable

A GBIC (Gigabit Interface Converter) is a module that fits into the GBIC minihub
(interface card) that is located at the rear of the 1 GB interface controller enclosure
(Figure 2-16). Each GBIC minihub has two GBIC modules. You connect the host-interface
or drive-interface cables to the respective GBIC module, which passes the signal to the
minihub.

Removing and Installing a GBIC Module
You can hot swap a failed GBIC module, replacing it while the controller enclosure is in
operation. If you replace the GBIC module and continue to experience problems, the
controller enclosure may have defective components or connections. Check the storage
management software (TPSSM7) for indications of other component failures.
