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 outlet 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.

NPS-2HD Heavy Duty Network Power Switch; 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
NPS-2HD Heavy Duty Network Power Switch gives you the
ability to perform this function 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 NPS-2HD can communicate over any TCP/IP network using
standard Telnet, or out-of-band using an external modem and
terminal emulation. Each outlet 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 NPS command menu via network. The NPS
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 NPS can be configured over the network, via modem, or
locally via the NPS Console Port. Easy-to-use commands let you
assign a location name, set system parameters and view plug
status. Outlets can be switched On, Off, or Booted using plug
numbers or names.
Features:
·Dual 20 Amp Circuits
·On/Off/Reboot Switching
·Integral 10Base-T Interface
·RS232 Modem and Console Ports
·Outlet-Specific Password Security
·Network Security Features
·Manual On/Off Buttons

2. Unit Description
2.1. Front Panel
As shown in Figure 2.1, the NPS-2HD front panel includes a
series of LED indicators which function as follows:
ÀON: Lights when AC Power is applied to the NPS-2HD.
ÁRDY: Flashes when the NPS-2HD is ready to receive
commands.
ÂRXD: Lights when the NPS-2HD receives commands.
ÃDCD: Lights when the Modem Port detects the Carrier.
ÄNET: Lights when a Telnet session is in progress.
ÅPlug Indicators and Manual Control Buttons: An
On/Off Indicator and Manual Control Button for each
switched plug. To manually switch a plug "On" or "Off",
press and hold the appropriate Manual Control Button for
one second; the corresponding plug will be toggled
On or Off.
Note: If desired, the Manual Control Buttons can
also be disabled as described in Section 5.4.

2.2. Back Panel
ÀBus 2 (Plug 2): Includes the following components:
A) Power Inlet: Supplies power for Bus 2.
B) Circuit Breaker: 115 VAC, 20 Amps
C) Switched Outlet: Each bus can switch up to 20 Amps.
ÁBus 1 (Plug 1): Same as Item 1 above, except the Bus 1
Power Inlet supplies power to Bus 1.
ÂNetwork 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 NPS-2HD features a 10BaseT interface. When
connecting the NPS 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.
ÃModem Port: A Male RS-232, DB9 Connector, DTE
configuration. For connection to an external modem.
ÄConsole Port: A Male RS-232, DB9 Connector, DTE
configuration. For connection to a local PC.
ÅOption Switches: A bank of four DIP Switches which
select default settings for the baud rate and other features.
ÆDefault Button: Used in conjunction with the Reset
Button to reset the unit to defaults (see Section 4.3.)
ÇReset Button: Used in conjunction with the Default
Button to reset the unit to defaults (see Section 4.3.)
