Chapter 1:
About the Redundant Power Supply
Overview
Note: The VSER-RPU-SYS is compatible with V2H124-24 and V2H124-24T only.
This VSER-RPU-SYS External Redundant Power Supply (RPS) can supply 600
Watts of backup power to four switching devices in the event of an AC loss or failure
of an internal power supply.
The system operates in a parallel capacity with a switch’s internal power supply. If a
switch's internal power supply fails, the RPS will support the full load of the switch
without affecting network operation.
Features and Benefits
• Supports four switching devices with 12V DC output
• Easy management LEDs located on the front panel
• AC line cord can draw power from a different supply circuit
• DC line cord provides backup power to the attached device
• The power supply will operate under a no-load condition.
Front and Rear Panels
Four power indicators (LEDs) and one fan indicator are located on the RPS’s front
panel. The AC supply and DC backup receptacles are located on the RPS’s rear
panel.

Installation
Note: The VSER-RPU-SYS is compatible with V2H124-24 and V2H124-24T only.
The RPS may be placed on a desktop or mounted in a rack.
Caution: DO NOT place the RPS on the floor as the case is not waterproof. It is
recommended that this RPS be installed in a network equipment rack.
Selecting a Site
RPS units can be mounted in a standard 19-inch equipment rack or on a flat surface.
Be sure to follow the guidelines below when choosing a location.
• The site should:
• be at the center of all the devices you want to link and near a power outlet.
• be able to maintain its temperature within 0 to 40 °C (32 to 104 °F) and its
humidity within 5% to 95%, non-condensing
• provide adequate space (approximately two inches) on all sides for proper air
flow
• be accessible for installing, cabling and maintaining the devices
• allow the status LEDs to be clearly visible
• Make sure that a separate grounded power outlet that provides 100 to 240
VAC, 50-60 Hz, is within 2.44 m (8 feet) of each device and is powered from an
independent circuit breaker. As with any equipment, using a filter or surge
suppressor is recommended.
Equipment Checklist
After unpacking the RPS, check the contents to be sure you have received all the
components. Then, before beginning the installation, be sure you have all other
necessary installation equipment.

• Any previous Return Material Authorization (RMA) numbers
Optional Rack-Mounting Equipment
If you plan to rack-mount the RPS, be sure to have the following equipment
available:
• Four mounting screws for each device you plan to install in a rack—these are not
included
• A screwdriver (Phillips or flathead, depending on the type of screws used)
Mounting
RPS units can be mounted in a standard 19-inch equipment rack or on a desktop or
shelf. Mounting instructions for each type of site follow.
Rack Mounting
Before rack mounting the unit, pay particular attention to the following factors:
• Temperature: Since the temperature within a rack assembly may be higher than
the ambient room temperature, check that the rack-environment temperature is
within the specified operating temperature range.
• Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.
• Circuit Overloading: Be sure that the supply circuit to the rack assembly is not
overloaded.
• Grounding: Rack-mounted equipment should be properly grounded. Particular
attention should be given to supply connections other than direct connections to
the mains.

Desktop or Shelf Mounting
1. Attach the four adhesive feet to the bottom of the first RPS unit.
Figure 2-3. Attaching the Adhesive Feet
2. Set the device on a flat surface near an AC power source, making sure there
are at least two inches of space on all sides for proper air flow.
Connecting Switches to the RPS
Caution: DO NOT connect the RPS to an AC power source until DC power cords have
been connected to the supported switches.
To connect switches to the RPS, refer to Figure 2-4 and Figure 2-5 and proceed as
follows:
1. Power up the switch by connecting one end of the AC cord to the AC receptacle
on the supported switch, and the other end to a grounded power outlet.
Figure 2-4. Power Receptacle
2. Connect one end of a DC cord to the redundant power receptacle on the
supported switch and the other end to an available receptacle on the RPS.
3. Repeat steps 1 and 2 for connecting up to four supported switches to the RPS.

5. Check the LEDs on the RPS to ensure proper operation. The Fan LED and the
RPS LED for connected switches should light up. If the LEDs indicate
otherwise, see "Troubleshooting" on page A-1 for more information.
