This chapter describes the HRPSU (High Power Redundant Power Supply Unit)
power rack and power supply module, and describes preparing for installation.

Introduction to the HRPSU

The HRPSU is a hot-swappable power supply that provides uninterrupted
operation to network devices in the event of a network device power supply
failure. The HRPSU is a standalone unit that can support up to four network
devices equipped with redundant power supply outlets.

Chapter 1

Overview of the HRPSU

114312 Rev. C

The HRPSU is a modular system consisting of a power rack (Order No.
AA0002001) with slots for four power supply modules (Order No. AA0005003).
You can install as many modules as needed, between one and four, in the power
rack. Figure 1-1 shows an HRPSU with all four power supply modules installed.

Installing and Maintaining the HRPSU

The HRPSU supports devices requiring up to 210 watts of power, as well as those
with lower power requirements. Each power supply module in the HRPSU
operates independently. For example, if you need to replace a power supply
module, you can turn off that module’s power switch, leaving the other modules
operational.

Figure 1-2 shows the front of the HRPSU with the front panels removed from two
slots, and a power supply module. The blank front panel on each power supply
slot normally remains on the HRPSU until a module is installed. The power
supply module, which has a permanent front panel, is provided with a latch for
handling the module and for keeping it in place during operation.

Figure 1-2. HRPSU Power Rack and Power Supply Module

114312 Rev. C

Overview of the HRPSU

Hot-swap connectors on each power supply module connect the input and output
signals of the power supply to the power rack backplane. The hot-swappable
feature allows you to install the HRPSU without turning off the power to the
network devices. Redundancy is provided with no down-time on the network.

A safety door inside each power supply slot prevents hands or other objects from
touching the connector on the backplane. In Figure 1-2, the open slot on the right
shows a safety door in locked position. The open slot on the left shows the power
supply connector on the backplane.

When you insert a power supply module into the slot, the flange on the rear of the
module releases the safety door, allo wing the module to connect to the backplane.
The module’s power switch, located on the front panel, is recessed deeply to
prevent you from accidentally turning off the module.

Figure 1-3 shows the rear of the HRPSU power rack. Each power supply slot is
identified by a number (1 - 4) stamped into the metal at the back upper edge of the
HRPSU power rack.

Installing and Maintaining the HRPSU

For network devices that use 16-pin cables, you must install a connector adapter to
attach the cable to the HRPSU.

Depending on the particular network device type, the HRPSU attaches to network
devices using 16-pin cables or 24-pin cables. For example:

• The ASN uses a single 24-pin cable.

• BayStack and Distributed 5000 device’s use a single 16-pin cable.

• The 28000 family devices use two 16-pin cables.
Standoffs are provided for 24-pin cable connections, and for attaching 16-pin

adapters for those network devices using 16-pin cables. Once all cabling is
complete and the AC power is turned on, the HRPSU is enabled; signals
automatically sent to the network device inform it of the presence of the HRPSU

-- no other setup is required.
The HRPSU power switch turns off all power to the unit. The AC power cord

plugs into a wall outlet. This allows the network device to have an AC power
source separate from the HRPSU. The HRPSU requires a dedicated 15-A branch
circuit for 120-V AC power service.

North American and Japanese users need to use the Bay Networks 15-A power
cords for their countries (Order Nos. AA0018020 and AA0020001, respectively).
All other countries use the standard Bay Networks 10-A power cord, at 240 V A C,
for their particular country.

Preparing for Installation

Before you install the HRPSU:

• Check your shipment.

- Verify that the items you received match the packing list attached to
the shipping container.

- Inspect all items for damage.

If any parts are missing or damaged, contact the Bay Networks Technical
Response Center for assistance.

• Make sure that your site meets the electrical requirements described in
Appendix A.
