Installation Instructions
Secure Racking
If Secure Racked units are installed in a closed or multi-unit rack assembly, they may
require further evaluation by Certification Agencies. The following items must be
considered.
1. The ambient within the rack may be greater than room ambient. Installation
should be such that the amount of air flow required for safe operation is not
compromised. The maximum temperature for the equipment in this environment is
60°C. Consideration should be given to the maximum rated ambient.
2. Installation should be such that a hazardous stability condition is not achieved due
to uneven loading.
Input Supply
Check nameplate ratings to assure there is no overloading of supply circuits that could
have an effect on overcurrent protection and supply wiring.
Grounding
Reliable earthing of this equipment must be maintained. Particular attention should
be given to supply connections when connecting to power strips, rather than direct
connections to the branch circuit.
No Serviceable Parts Inside; Authorized Service Personnel Only
Do not attempt to repair or service this device yourself. Internal components must be
serviced by authorized personnel only.

• LithiumBattery
CAUTION:Dangerofexplosionifbatteryisincorrectlyreplaced.Replace
onlywithsameorequivalenttyperecommendedbythemanufacturer.
Discardusedbatteriesaccordingtothemanufacturer'sinstructions.
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the power
source and contact qualified service personnel:
1. If the power wire becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device has been exposed to rain
or water.
Two Power Supplies
Note that RPC series units feature two separate power circuits and a separate power
supply cable for each power inlet. Make certain to disconnect all power supply cables
from their power source before attempting to service or remove the unit.

1. Introduction
This Hardware Guide covers set-up and installation for our RPC Series Network Power
Switches. RPC Series units are designed to simplify the process of remotely managing
vital network elements located at distant network equipment sites and off-site facilities
by providing secure remote access to DC power switching and reboot functions at the
remote network equipment site.
Note: For instructions regarding configuration and operation of the RPC Series
Device, please refer to the WTI Firmware Guide.
Model Numbers Covered
This Hardware Guide discusses all WTI RPC Series products. Throughout this
Hardware Guide, all of these units are referred to as the "RPC."

Unit Description
2.5. Additional Button Functions
The Default and Reset buttons on the RPC front panel can be used to perform the
functions described below:
Notes:
• AllFrontPanelButtonfunctionscanalsobedisabledviatheSystem
Parametersmenu,asdescribedintheWTI Firmware Guide.
• WhentheRPCisresettofactorydefaults,alluser-definedconfiguration
parameterswillbecleared,andthedefault“super”useraccountwillalso
berestored.
1. RebootOperatingSystem:
a) Press and hold the Reset button for five seconds, and then release it.
b) The RPC will reboot it's operating system; all circuits will be left in their current
On/Off state.
2. SetParameterstoFactoryDefaults:
a) Simultaneously press both the Default button and the Reset button, hold them
for five seconds, and then release them.
b) All RPC parameters will be reset to their original factory default settings, and
the unit will then reboot. All circuits will be left in their current On/Off state.
3. Toggle/DefaultAllCircuits:
a) Press the Default button, hold it for five seconds, and then release the Default
Button.
b) The RPC will switch all circuits to the Off state. If all circuits are already in the
Off state, then the unit will reset all circuits to their user defined default states.

3. Getting Started
This section describes a simplified bench test procedure for the RPC, which will allow
you to communicate with the unit in order to demonstrate basic features and check for
proper operation.
Notes:
• ThereareseparateHardwareInstallationproceduresforRPC-4850series
unitsandRPC-40L8A4seriesunits.RPC-4850seriesunitsarediscussedin
Section4.1andRPC-40L8A4seriesunitsarediscussedinSection4.2.
• FormoreinformationregardinginstallingtheRPChardwareinaworking
networkenvironment,pleaserefertoSection4.
• Forinstructionsregardingconfigurationsoptionsandadvancedoperating
features, please refer to the WTI Firmware Guide.
3.1. Apply Power to the RPC Unit
3.1.1. Connecting RPC-4850 Series Units to Power
Refer to power rating nameplate on the back panel, and then connect the RPC-4850
series unit to an appropriate power source
The RPC-4850 features two separate DC inputs; connect power wires to the unit's
Circuit "A" and/or Circuit "B" terminal blocks, then connect the wires to an appropriate
power supply. The ON LED should light, and the RDY LED should begin to flash. This
indicates that the RPC-4850 is ready to receive commands.
Notes:
• FormoreinformationregardingconnectingpowertoRPC-4850SeriesUnits,
please refer to Section4.1.
• Forthepurposeofthisbenchtestprocedure,itisnotnecessarytoconnect
powertobothinputcircuits;eithercircuitwillsupplypowerforoperationand
controlfunctions.However,whenpowerisconnectedtobothcircuits,this
allowsthesecondcircuittofunctionasaback-upintheeventofapower
outage.
• Eachindividualoutputcircuitwillsupportupto15Ampsmaximum.Thetotal
foralleightcircuitscannotexceed50Amps.
Warning: An exposed wire lead from a DC input power source can
conduct harmful levels of electricity. Make certain that no exposed portion
of the DC input wire extends from the terminal block.
