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
(DUA1607-4AAA0X), your Advanced RPS
Chassis user guide (DUA1607-0AAA0X) and
the product user guide. If you are unable to
find the information or are unsure, please
contact your supplier.
Redundancy
Use a standard Type 2 DC cable (as supplied
with your power module) to provide managed
redundancy connecting the outlet of the Type
2A Power Module to the RPS socket on the
rear of the SuperStack device. The device you
are connecting must be one with the
auto-enable feature present for this
redundancy.
Full Redundancy
Use the Type 2 ‘Y’ cable to provide full
redundancy (resilience) connecting one short
lead to each of the two Type 2A Power
Module outlets installed in the RPS chassis and
the long lead to the RPS socket on the rear of
the SuperStack device.
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.

Introduction
The SuperStack
®
II Advanced Redundant Power
System (ARPS) provides redundant power
supplies to products in the 3Com SuperStack II
range. These optional Type 2 Advanced RPS ‘Y’
cables (3C16078) are required to connect the
DC power from Type 2A or Type 2 Power
Modules to a SuperStack device when you need
resilience. This cable allows you to hot-swap a
module while maintaining the power supply to
your network unit.
For more general information and warranty
details for these products, please refer to
SuperStack II Advanced RPS User Guide
(DUA1607-0AAA0X).
This guide is written for the installation
engineer and the network administrator who
