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.

7. Using the same screw driver, tighten the three screws on the RPS.
8. Connect the Switch 2000 AC power cord to an AC outlet.
9. Connect the RPS AC power cord to an AC outlet (on a different
breaker if possible).
Both AC power cords must be connected to provide full redundancy.
The RPS LED on the Switch 2000 will be on solid to indicate the RPS
is working properly. The following table explains the LEDs that
reflect the operating state of the RPS.

Frequently Asked Questions
The following table lists questions and answers about the Redundant Power
Supply:
Question Answer
What is the difference between a UPS and an RPS? A UPS (Uninterruptible Power Supply) is an external
power backup device. The UPS serves as a battery
backup, so that if your AC power source fails (as in a
brownout or blackout), the UPS will still provide power. To
order an HP UPS, call 1-800-538-8787.
An RPS (Redundant Power Supply) is an external power
backup device. The power supply of the RPS is duplicated
(redundant) of the Switch 2000, so that if one power supply
component fails the RPS will still provide power.
Should I keep my device’s AC power cord connected? Yes. Otherwise, you do not have redundant power.
Do I have to plug both AC power cords into different AC
power sources? We recommend that you connect each AC power cord to a different AC power source but it is not required.

Safety Information
Safety Symbols
Documentation reference symbol. If the product is marked with this symbol, refer
to the product documentation to get more information about the product.
WARNING A WARNING in the manual denotes a hazard that can cause injury or death.
CAUTION A CAUTION in the manual denotes a hazard that can damage equipment.
Do not proceed beyond a WARNING or CAUTION notice until you have understood
the hazardous conditions and have taken appropriate steps.
Grounding
These are safety class I products and have protective earthing terminals. There must be an
uninterruptible safety earth ground from the main power source to the product’s input wiring
terminals, power cord, or supplied power cord set. Whenever it is likely that the protection has
been impaired, disconnect the power cord until the ground has been restored.
For LAN cable grounding:
If your LAN covers an area served by more than one power distribution system, be
sure their safety grounds are securely interconnected.
LAN cables may occasionally be subject to hazardous transient voltages (such as
lightning or disturbances in the electrical utilities power grid). Handle exposed metal
components of the network with caution.
Servicing
There are no user-serviceable parts inside these products. Any servicing, adjustment,
maintenance, or repair must be performed only by service-trained personnel.
These products do not have a power switch; they are powered on when the power cord is
plugged in.
