HP StorageWorks 9000 - Virtual Library System - Installing Pdus

The expansion disk array enclosures come with capacity options of either 7.5 TB or 10 TB. Install the
same capacity expansion disk array enclosures as you purchased for the base disk array enclosure;
mixing 7.5 TB capacity with 10 TB capacity is not recommended.
Installing PDUs
If the rack you are using already has PDUs (power distribution units) installed, skip this procedure.
