Learn how to connect the
controller to a power source.
About this task
After installing the controller to a rack or to a table, connect the controller to a
power source. To view port information, see E2122 back panel features.
Procedure
Locate the power cord retention
strap from the AC power cord bracket and cable clamp kit:
Insert the locking tab end of the retention strap into the receiver hole
located to the right of power supply module #1.
Adjust the slider of the retention strap to a desired position while
pushing up the locking tab on the bottom of the slider.
Connect the two AC power cables to power supplies 1 and 2.
These two power supplies combine to create an optional redundant power
supply.
Optionally, wrap the slider strap over the power cord and lock it securely in
place.
Plug the other end of the cables into grounded electrical outlets or to
separate power sources such as an uninterrupted power supply (UPS) or a power
distribution unit (PDU).
For USB key storage only: Although the controller has 5 USB
connectors (two on the front panel and three on the back panel), only one
USB connector can be in use at any one time.
