Make sure you use the correct type of ’Y’ cable for the right module
combination. See “Power Modules” on page 15 for front views of
the different connectors.
If one of the power modules fails, the other module will take the full
load. The faulty module can be “hot-swapped”, that is, you do not
need to remove power from the chassis before you remove or insert
a power module, to return the system to full redundancy. This
prevents the reset that occurs in the managed redundancy mode.
Refer to the Advanced RPS Type 3 Power Module Installation Guide
and Advanced RPS Type 3 ‘Y’ Cable Installation Guide.
