Notes
• Drives in the Tape Libraries and Autoload-
er do not have a second SAS port, so
they connect to only one switch.

fan-out cable can connect up to four tape
drives to a single switch port. Coil any
unused ends and secure them to the rack
to minimize strain on the cable.
• Available SAS fanout cables:

2X1 Mini-SAS Cable Kit
• AN976A – 4m External Mini-SAS to
