User's Guide

Warnings and Cautions:
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.
•Shock Hazard - Do Not Enter
Nameplate Power Warning
This device should only be operated with the type of power
source indicated on the instrument nameplate. If you are not
sure of the type of power service available, consult your local
power company.
•Connect unit only to a properly measured supply. Use
only three wire cord which is provided with the unit.
•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.
Rack Mount Installation
When installing this device in an instrument rack, the following
factors must be accounted for:
1. Enclosed Racks: Enclosed racks must provide adequate
ventilation. Make certain that the rack is not overly
crowded and note that each unit in the rack generates its
own heat. An enclosed rack should have louvered sides
and a fan to circulate cooling air.
When mounting the unit in an enclosed rack with a
ventilation fan at the top of the rack, note that excessive
heat generated by devices at the bottom of the rack can be
drawn upward and into the ventilation slots of units
located at the top. Make certain to provide adequate
ventilation for equipment installed at the bottom of
the rack.

Rack Mount Installation (Continued)
1. Enclosed Racks (Continued):
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 45°C. Consideration should be given to the
maximum rated ambient.
Installation should be such that a hazardous stability
condition is not achieved due to uneven loading.
2. Open Racks: Make certain that the rack frame does not
block the ventilation slots on the instrument cover. If the
device is installed on sliders, check the unit when seated
all the way into the rack to make certain that ventilation
slots are not blocked.
Ventilation
Slots in the instrument cover are provided to allow ventilation
for heat dissipation. To ensure safe, reliable operation, these
openings must not be covered or blocked.
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 cord becomes frayed or damaged.
2. If liquid has been spilled into the device or if the device
has been exposed to rain or water.

RPC-4840N Remote Power Controller; User's Guide

1. Introduction
Network equipment sometimes "locks-up", requiring a service
call just to flip the power switch to perform a simple reboot. The
RPC-4840N Heavy Duty Remote Power Controller gives you the
ability to reboot DC powered equipment from anywhere on the
LAN/WAN, or if the network is down, to simply dial-in from a
modem for out-of-band power control.
Intelligent Power Control
The RPC-4840N can communicate over any TCP/IP network
using standard Telnet, or out-of-band using an external modem
and terminal emulation. Each DC circuit can be assigned an
individual password, device name, reboot delay time and unique
power-up default status.
Security
Address specific IP security masks prevent unauthorized users
from accessing the RPC command menu via network. The RPC
provides two separate password security levels; System level and
User level. The System password allows access to all
configuration and command functions. The User password
allows limited access to command functions.
Easy to Use, Easy to Configure
The RPC-4840N can be configured over the network, via modem,
or locally via the RPC Console Port. Easy-to-use commands let
you assign a location name, set system parameters and view
circuit status. Circuits can be switched On, Off, or Booted using
circuit numbers or user-defined names.
Heavy Duty DC Power Control
The RPC-4840N can control up to 40 amps of DC power per
circuit. Since larger routers require as much as 30 amps, the
RPC has power control to spare. The optional second Circuit
Module allows the RPC to control power for two 40 amp, DC
powered instruments.

2. Unit Description
2.1. Front Panel
As shown in Figure 2.1, the RPC-4840N front panel includes a
series of LED indicators which function as follows:
ÀON: Lights when Power is applied to the Control Section.
ÁRDY: Flashes when the RPC-4840N is ready to receive
commands. Indicates that the Console Port has received
the "Ready" signal from the control device.
ÂRXD: Lights when the RPC-4840N receives commands.
ÃCircuit 1 Indicator: Lights when the Circuit 1 Switch is
closed (Power ON to connected device.)
ÄCircuit 2 Indicator: Lights when the optional Circuit 2
Switch is closed (Power ON to connected device.)
2.2. Back Panel
ÀNetwork Port and Activity Indicator: A 10BaseT, RJ45
Ethernet port for connection to your TCP/IP network. To
communicate via network, you must first specify network
parameters as described in Section 5.6.
Note: The RPC-4840N features a 10BaseT interface.
When connecting the RPC to a 100BaseT interface, note
that most 100BaseT router switches will autosense to
determine if the device is 100BaseT or 10BaseT and then
configure the network interface accordingly. If your router
switch does not autosense, then the network interface port
must be manually set to 10BaseT.

Figure 2.1: Front Panel

ÁOptions Switch: Four DIP Switches which set the default
baud rate, boot delay, echo mode, and timeout.
ÂDefault Button: Used in conjunction with the Reset
Button to reset the unit to defaults (see Section 4.3.)
ÃConsole Port: A Male RS-232, DB9 Connector, DTE
configuration. For connection to a local PC.
ÄModem Port: A Male RS-232, DB9 Connector, DTE
configuration. For connection to an external modem.
ÅReset Button: Used in conjunction with the Default
Button to reset the unit to defaults (see Section 4.3.)
ÆCircuit Module 1: For connection to your DC power
supply and DC powered device. Each circuit is capable of
switching up to 40 Amps. Note that power for control
functions is also derived from the Circuit 1 input terminal.
A. ON Indicator: Lights when the corresponding Circuit
Module is switched On (switch closed).
B. Emergency Override Breaker: If the circuit is
overloaded, the breaker pops out and opens the circuit.
If necessary the Override Breaker can also be manually
pulled out to open the circuit. To reset the circuit,
press the Override Breaker in.
ÇCircuit Module 2 (Optional): For connection to a second
DC power supply and DC powered device. Same as
Circuit Module 1.
