The Disk Array can tolerate the loss
of connection to AC Box 1 or AC Box 2.
Specific power plugs and receptacles are required for the XP128,
depending on the power option you specify when ordering the HP Disk
Array XP128. The power cords on 60 Hz cabinets are shipped with plugs
attached. The power cords on 50 Hz cabinets are shipped without plugs.
Customers are responsible for having the correct plugs and receptacles
installed by an electrician in compliance with local electrical requirements
and practices.
When installing the receptacles, the electrician must ensure that each
receptacle has its own neutral (if required) and ground. Using the same
neutral/ground for more than one circuit causes voltage loss and heat
problems. It can create a fire hazard. A shared neutral conductor that fails
open-circuit can cause overvoltage damage to equipment.
