3Com SS II ADVANCED RPS PWR Y-CABLE User manual

Installing The Cable
The SuperStack II Advanced RPS and its modules
may be hot-connected to SuperStack II units.
Connecting Cables
Before attaching the cables, check that the power
demand of the product does not exceed the
capacity of the Power Module you are connecting.
This information is given in the Power Module user
guide (DUA1607-2AAA0X), your Advanced RPS
Chassis user guide (part number DUA1607-0AAA0X)
and the product user guide. If you are unable to
find the information or are unsure, please contact
your supplier.
When mating the special RPS connectors
to the inlet and outlet sockets, take care to
ensure that the retaining spring, where
fitted, locates outside the plug casing.
Redundancy
Use a standard DC cable (as supplied with your
power module) to provide managed redundancy
connecting the outlet of the power module to the
inlet of the product. The product you are
connecting must be one with the auto-enable
feature present for this redundancy.
Full Redundancy
Use the ‘Y’ cable to provide full redundancy
(resilience) connecting one short lead to each of
two module outlets on the RPS and the long lead to
the product inlet.
After installing the cable, this guide should be
stored with your other 3Com user guides.
Fault Diagnosis
The LEDs on the front of the Advanced RPS Chassis
provide simple at-a-glance fault diagnosis of the
installed Power Modules.
If you suspect a problem:
■ Check that you have allowed at least five
seconds for the Power Module to warm up.
■ Check the status of the LEDs on the front panel
of the chassis, as described in the SuperStack II
Advanced RPS User Guide, part number
DUA1607-0AAA0X.
■ Ensure the Power Module is correctly installed
in the Chassis.
■ Check the RPS cables are correctly engaged
and locked.
If you cannot rectify the fault, contact your supplier,
giving the following information:
■ the product number.
■ the Power Module serial number.
■ a brief description of the fault.
Your supplier will advise you on your next course of
action.
