HP Switch 2000 Redundant Power Supply

At A Glance

The HP J3136A AdvanceStack Switch 2000 Redundant Power Supply

provides redundant DC power to the HP J3100A AdvanceStack Switch 2000.

The Redundant Power Supply (RPS) shares the power load with the Switch

2000’s main power supply. If the Switch 2000’s power supply components

were to fail, the RPS power supply component will instantly supply power to

the Switch 2000.

Features

Network Connections Provides fully redundant power to the Switch 2000.

Modular, Easy-to-Use Design The RPS is easy to mount on the back of the Switch 2000.

Each Switch 2000 has an RPS LED to report the status of the Redundant Power

Supply.

RPS status information available from HP Stack Manager (Windows 3.1

software shipped with the devices that support the RPS) and HP Interconnect

Manager.

Management SNMP indication on the RPS connection and the RPS fault condition through the

connected devices.

Installation Steps

To add redundant power to your Switch 2000, follow these steps:

Warning 1. Disconnect the power supply from the Switch 2000 before

installing the RPS. Electrical shock or other injury can result

if you attempt to install the module without unplugging the

Switch 2000.

2. Using a Torx T-10 or flat-bladed screw driver, loosen the five cap-

tured screws on the cover plate on the back of the Switch 2000.

3. Store the cover plate.

(Steps continued on next page.)

4. Notice that the RPS has three metal tabs on its bottom.

5. Line up the RPS metal tabs to the Switch 2000 and insert the tabs

into the three slots on the Switch 2000 as shown below.

6. Rotate the RPS up and towards the Switch 2000. Then push the RPS

until it is firmly seated into the connector inside the Switch 2000.
