Set the I.D. Selection and Configuration Switches
Each power supply in a redundant system must be assigned a
different identification number. To do this, you must set the I.D.
selection switches located on the left side of the module
(shown below). A cutout in the metal cover of the module provides
access to these switches.
Switches Are set
1, 2, 3, 4 for the power supply identification number
5, 6 based on the configuration zone
To set the switches:
1. Close the I.D selection switch (1, 2, 3, or 4) that represents the
number you selected for that power supply.
2. Determine the configuration zone being used so you can set
switches 5 and 6.
To determine the configuration zone, you must know the maximum
chassis current draw and the ambient air temperature of the chassis.
