Placing power cords for the 5079
Youneed to provide the appropriate receptacles for the power cords shipped with
your 5079. The usable length of the upper unit power cord is 4 ft. (1.2 m) shorter
than the length of the lower unit power cord.
Redundant links
Aredundant link is a secondary HSL connection that your system can use if the
primary link experiences a failure. Youcan create a redundant link configuration
by connecting an extra HSL cable link between the expansion units and the system
unit.
Yournew expansion unit has disk units. To ensure continued access to your disk
units in the event of a link failure, use a redundant link configuration when you
plan your cable layout.
Refer to Figure1 to see how to plan your cables with a redundant link
configuration with one expansion unit. If you are linking two, expansion units
refer to Figure2 on page 4. If you are setting up a 5079, refer to Figure3 on page 4.
