2: Connecting to a Host and Powering On and Off
Powering Off the 2 Gb TP9100 Tower or a Single Enclosure
Besides the main breaker switch at the bottom of each PDU, the rack PDUs have breaker
switches at each 12U of space so that you can power off three enclosures and leave others
powered on.
To power off a single enclosure or tower storage system, follow these steps:
1. Ensure that users are logged off of the affected systems.
2. Move the power switch on the rear of each PSU/cooling module to the “Off”
position (position “
I”=on, “O”=off).
3. If appropriate, disconnect the PDU power cords from the power sources.
