electricity than dry environments. A grounding strap is warranted
whenever danger of static electricity exists.
• Ensure you have a stable, clean working environment. Dust and dirt can
get into components and cause a malfunction. Use containers to keep
small components separated.
Precautions
Computer components and electronic circuit boards can be damaged by
discharges of static electricity. Working on the computers that are still connected to a power supply can be extremely dangerous.
• Adequate lighting and proper tools can prevent you from accidentally
damaging the internal components.
• Most of the procedures that follow require only a few simple tools,
Follow the guidelines below to avoid damage to your computer or yourself:
including the following:
• A Philips screwdriver
• Always disconnect the unit from the power outlet whenever you are
• A flat-tipped screwdriver
working inside the case.
• A set of jeweler’s screwdrivers
• If possible, wear a grounded wrist strap when you are working inside
• A grounding strap
the computer case. Alternatively, discharge any static electricity by
touching the bare metal chassis of the unit case, or the bare metal body
of any other grounded appliance.
• An anti-static pad
• Using your fingers can disconnect most of the connections. It is
recommended that you do not use needle-nosed pliers to disconnect
connections as these can damage the soft metal or plastic parts of the
connectors.
• Hold electronic circuit boards (such as the NSA1083 board) by the edges
only. Do not touch the components on the board unless it is necessary
to do so. Don’t flex or stress the circuit board.
• Before working on internal components, make sure that the power
• Leave all components inside the static-proof packaging that they
is off. Ground yourself before touching any internal components, by
touching a metal object. Static electricity can damage many of the
electronic components. Humid environment tends to have less static

• Use correct screws and do not over tighten screws.

Chapter 2: Setting the Jumpers
Jumper Settings
A jumper is the simplest kind of electric switch consisting of two metal
pins, which function as electrical contact points, and a cap or plug. When
setting the jumpers, ensure that the jumper caps are placed on the correct
pins.
When the jumper cap is placed on both pins, the jumper is short. If you
remove the jumper cap, or place the jumper cap on just one pin, the
jumper is open.
Refer to the illustrations below for examples of what the 2-pin and 3-pin
jumpers look like when they are short (on) and open (off).
Two-Pin Jumpers: Open (Left) and Short (Right)
Three-Pin Jumpers: Pins 1 and 2 Are Short

About BIOS Setup
When to Configure the BIOS
The BIOS (Basic Input and Output System) Setup program is a menu driven
utility that enables you to make changes to the system configuration and
tailor your system to suit your individual work needs. BIOS is a ROM-based
configuration utility that displays the system’s configuration status and
provides you with options to set the system parameters.
This program should be executed under the following conditions:
• When changing the system configuration
• When a configuration error is detected by the system and you are
prompted to make changes to the Setup program
•
•
•
•
These parameters are stored in non-volatile battery-backed-up CMOS RAM
that saves this information even when the power is turned off. When the
system is turned back on, the system is configured with the values found
in CMOS.
When redefining the communication ports to prevent any conflicts
When making changes to the Power Management configuration
When changing the password or making other changes to the security
setup
Normally, CMOS setup is needed when the system hardware is not consistent with the information contained in the CMOS RAM, whenever the
CMOS RAM has lost power, or the system features need to be changed.
With easy-to-use menus, you can configure such items as:
•
•
•
•
When resetting the system clock
Hard drives, diskette drives, and peripherals
Video display type and display options
Password protection from unauthorized use
Power management features
The settings made in the Setup program intimately affect how the computer performs. It is important, therefore, first to try to understand all the
Setup options, and second, to make settings appropriate for the way you
use the computer.
Preparing for BIOS Configuration
To access the BIOS, you will need a computer with HyperTerminal (or any
telnet client) installed and the serial cable that is supplied in the NSA 1083
package.
Note: The following procedures are for accessing BIOS Setup on Windows
XP. If you are accessing BIOS Setup on another system, the procedures may
be different.

Power Management Setup
EPP Mode Select
Power Management Setup lets you control the system power. The system
has various power-saving modes — including powering down the hard
disk, turning off the video, suspending to RAM, and software power down
— that allows the system to be automatically resumed by certain events.
Select EPP port type 1.7 or 1.9.
ECP Mode Use DMA
The power-saving modes can be controlled by timeouts. If the system is
inactive for a time, the timeouts begin counting. If inactivity continues
and reaches the defined timeout period, the system enters a powersaving
mode. If any item in the list of Reload Global Timer Events is enabled, then
any activity on that item will reset the timeout counters to zero.
When the on-board parallel port is set to ECP mode, the parallel port can
use DMA3 or DMA1.
PWR LED after PWR-ON
Set the behavior of PWR LED after the appliance is power on. By default,
the PWR LED is set to turn on after powering on the appliance.
If the system is suspended or has been powered down by software, it can
be resumed by a wake up call that is generated by incoming traffic to a
modem, a LAN card, a PCI card, or a fixed alarm on the system real-time
clock.
LAN ByPass Function
This set of options allow you to control the bypass function that NSA 1083
provides. By configuring LAN bypass, you can help ensure that traffic will
still be able to pass through the appliance even when there is a problem
with the platform. Configuring the bypass function is especially recommended for gateway security appliances.

Note: This is a write only field.
0 = Timer has not expired
1 = Timer has expired
Upon read, these bit values are undefined.
A Timer value of 1 to 7 is required to be
written before expiration of the hardware
timer. When the timer expires, all segments which have been enabled in bits 2:0
of Power On state Bypass Control Status
Register set relays closed to form bypass
segments. It is responsibility of software to
keep track of time to ensure writes to this
register occur no greater than TimerValueInSeconds / 2 .
Note: A read operation on Bypass Timer
Configuration Register should not cause
the timer value to refresh.
A write of the timer value will automatically reset the expiration timer and set it to
the value expressed in bit 2:0.
