Installing A Power Distribution Unit - NEC Express 5800 User Manual

Installing a Power Distribution Unit

If you are not using an Uninterruptible Power Source (UPS), AC power is
distributed to system components through a Power Distribution Unit (PDU). See
Figure 5-9.
The PDU comes equipped with a 15-foot power cord and can be installed either
in the bottom of the rack, or when rack space is at a premium, directly behind
your keyboard tray. See your configuration work sheet to determine the location
chosen for your PDU.
Note: When you install a PDU behind a keyboard tray,
the remaining workspace will be restricted. Therefore, it is
recommended that keyboard, mouse, monitor, and
connections to any port concentrator are completed before
you install a PDU behind a keyboard tray.
