HSV controller cabling
All data cables and power cables attach to the rear of the controller. Adjacent to each data connector
is a two-colored link status indicator. Table 5 identifies the status conditions presented by these
indicators.
NOTE:
These indicators do not indicate whether there is communication on the link, only whether the link
can transmit and receive data.
The data connections are the interfaces to the disk drive enclosures or loops (depending on your
configuration), the other controller, and the fabric. Fiber optic cables link the controllers to the fabric,
and, if an expansion cabinet is part of the configuration, link the expansion cabinet drive enclosures
