Installation and Maintenance
5.1 Installation
Rack Mounting of Systems
Observe the following precautions for rack stability and safety. Also refer to the rack
installation documentation(s) provided by rack manufacturer. Systems are considered to
be components in a rack. Thus, "component" refers to any system as well as to various
peripherals, products or supporting hardware. Please adhere to the following instructions
when installing the RPS system:
After installing components in a rack, never pull more than one component out of
the rack on its slide assemblies at one time. The weight of more than one extended
component could cause the rack to tip over and may result in serious injury.
Components should be installed in a rack by trained service technicians.
Do not move racks by yourself. Due to the height and weight of the rack, a
minimum of two people should accomplish this task.
Always load the rack from the bottom up, and load the heaviest item in the rack
first.
Make sure that the rack is level and stable before extending a component from the
rack.
Do not overload the AC supply branch circuit that provides power to the rack.
The total rack load should not exceed 80 percent of the branch circuit rating.
Ensure that proper airflow is provided to components in the rack.
Do not step on or stand on any component when servicing other components in a
rack.
The system chassis must be positively grounded to the rack cabinet frame. Do not
attempt to connect power to the system until grounding cables are connected.
Completed power and safety ground wiring must be inspected by a qualified
electrical inspector. An energy hazard will exist if the safety ground cable is
omitted or disconnected.
Mounting Instructions
Before you install the RPS Power Supply, consult Section 3.3 of this manual to confirm
that your switch supports the OPTIMAL POWER®RPS Series Model RPS5412.
Installing the RPS Power Supply on a Flat Surface
You can install the RPS5412 (Redundant Power Supply) RPS on any appropriate level
surface that can safely support the weight of the switches, the RPS Power Supply, and
their attached cables. There must be adequate space around the RPS Power Supply for

10
ventilation and to access cable connectors. Consider following steps to install the RPS
system on a flat surface.
Set the RPS Power Series RPS on the flat surface and check for proper ventilation
and air flow.
Allow at least 2 inches (5.1 cm) on each side for proper ventilation and 5 inches
(12.7 cm) at the back for AC and DC power-cord clearance.
Attach rubber feet on the bottom of the chassis to keep the unit from slipping.
Installing the RPS Power Supply in a Rack
The RPS Power Supply can be installed in most standard 19-inch racks. Consider
following steps to install RPS Power Series RPS in rack.
Use appropriate size screws to attach the RPS system to the 19-inch rack.
Position the RPS Power Series RPS in the rack and align the oval shaped holes on
the side of the RPS with the holes in the rack.
Insert and tighten two screws appropriate for your rack through each of the oval
shaped holes on the side of the RPS.
To Operate the RPS Power Supply after Installation
Model RPS5412 may be installed in environments that meet the environmental
characteristics specified in Chapter 2. It is recommended that sufficient ventilation gap be
provided above or below the RPS unit for proper air flow.
Once the RPS (redundant power supply) is mounted in the rack, it should be connected to
a switch (that only requires –52VDC or +12VDC power),and has a DC connector
located on rear panel as shown:
The figure shows where to connect the Optimal Power® RPS Model RPS5412 on the
NETGEAR® switch.
Note: The location of the redundant power supply connector on your switch may differ from
the illustration.

Next follow the instructions below:
To connect a redundant power supply (RPS) unit to the switch, first turn "OFF"
the NETGEAR® Ethernet switch.
Also, ensure that the power switch on the RPS unit RPS5412 is in "OFF" position.
Important Note: Always Turn "OFF" the AC power first when installing or
removing the RPS from the system. RPS device should not
be live inserted. That is, when AC is "ON" DONOT
connect the RPS cable to the RPS connector on the switch.
When the power is "OFF", you can remove the cover plate on the rear panel of the
NETGEAR® switch as shown on the previous page.
Now connect the RPS DC Connection Cable Model RPSC5412 to the appropriate
NETGEAR® PoE switch making sure the connections are well secured, and the
AC power is "OFF" to the switch and the RPS.
Connect the AC power cord to the RPS unit by plugging the free end of the power
cord into a standard three prong AC outlet.
Ensure that the AC power plug located at the rear end of the power supply is
connected to a clean and well-grounded Universal AC source.
Once all the wires are connected properly, Turn "ON" the rear panel switch for
the RPS (redundant power supply) unit.
The Green LED should light up. Indicating Power supply is “ON” and working
properly. Now the system is ready to operate to its required purpose.
5.2 Maintenance & Safety Instructions
Please use the following safety instructions to ensure your own personal safety and to help
protect your system from potential damage.
The Model RPS5412 should be treated with the sufficient care.
Do not open, service (or) repair any product by yourself.
Do not use abrasives or solvents, as they may mar surfaces.
Do not subject the unit to excessive temperature extremes.
Do not subject the unit to excessive moisture or spilled liquids.
Do not expose your system to direct heat, radiators, rain, dripping or splashing.
Do not subject the unit to sudden or severe shocks.
Never operate the Model RPS5412 with any of the covers removed.
Do not block cooling vents.
WARNING: Observe polarity when making connection to the rear of
RPS Model RPS5412

12
Do not push any objects into the openings of your system. Doing so can cause fire or
electric shock by shorting out interior components.
Use the product only with approved equipment.
Operate the product only from the type of external power source specified.
Use only approved power cable(s). If you have not been provided with a power cable
contact OPTIMAL POWER®.
To help prevent electric shock, plug the system and peripheral power cables into
properly grounded electrical outlets. Provided AC cable is equipped with three-prong
plugs to help ensure proper grounding.
Do not use adapter plugs or remove the grounding prong from a cable. If you must
use an extension cable, use a 3-wire cable with properly grounded plugs.
Observe extension cable and power strip ratings.
Make sure that the total ampere rating of all products plugged into the extension cable
or power strip does not exceed 80 percent of the ampere ratings limit for the
extension cable or power strip.
To help protect your system from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power
supply (UPS).
Position system cables and power cables (AC and DC) carefully; route cables so that
they cannot be stepped on or tripped over. Be sure that nothing rests on any cable.
Do not modify power cables or plugs.
Install the power supply before connecting the power cable to the power supply.
Unplug the power cable before removing the power supply.
If the system has multiple sources of power, disconnect power from the system by
unplugging all power cables from the power supplies.
A qualified electrician must perform all connections to AC and DC power and to
safety grounds. All electrical wiring must comply with applicable local or national
codes and practices.
Never defeat the ground conductor or operate the equipment in the absence of a
suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available.
5.3 Trouble-Shooting Instructions
If the RPS system is not working, check the following steps before calling the Authorized
Technician at Optimal Power®:
Check that Green Status LED is "ON".
Check that AC input power exists and that main switch is in the "ON" position.
Check that the required 6A@250V fuse at the back of the RPS is not blown.
Check that all the RPS DC Connection Cable Models RPSC5412 are connected and
well secured.
If after all these trouble shooting steps the unit does not start, do not try to repair the unit but call
the Technical Support.
