Set the Jumpers
Each power supply module has two jumpers located at the back edge of the module near the gold-plated edge connectors. The jumper selection provides the proper voltage regulation for the different power supply configurations. The power supply can be configured to support local or remote sensing by setting the jumpers.
To configure the supply:
-: )
For this configuration |
Set jumpers to: |
A single power supply in a power supply chassis |
right position |
connected to an I/O chassis thru a power cable |
|
All other configurations. (Power supplies are |
