Mbps connection is obtained, the LED is yellow.

Reset Switch

Resets the SonicWALL GX 250 or the SonicWALL GX 650 to its factory clean state. This may be

required if you forget the administrator password, or the SonicWALL firmware has become

corrupt.

There are two power input receptacles to connect the SonicWALL to the AC power

input. The unit comes standard with redundant hot swappable power supplies with

active power function correction (100-240 VAC 50/60 Hz).

Cooling Vents

The SonicWALL is convection cooled and has an internal fan that is not crucial to the

function of the GX, but provides additional cooling to the unit. Do not block the cooling

vents on the SonicWALL front and back panels.

5 Troubleshooting Guide

Tips for Cable/DSL Modem Users

No Internet Access

If you are experiencing problems connecting to the Internet after installing your SonicWALL,

you should turn off your cable modem for five (5)minutes, and then turn it back on. Restart the

SonicWALL and try to access it using the LAN IP address. This is an easy fix that’s worth trying

before contacting tech support.

If you are using

NAT with DHCP Client

network configuration, log into the SonicWALL and

click

General

, then

Network

. Verify that the

Host Name

field has information in it. Your ISP

may require a Host Name to connect to the Internet.

Some ISPs require the MAC address or the Ethernet address of the SonicWALL before the IP

lease can be established. The MAC address of the SonicWALL is the serial number located on

the bottom of the appliance. It is also displayed on the

Status

page of the

General

window.

Cannot Maintain IP Address

Typically, cable modem users obtain an IP address dynamically via DHCP. The IP address is

leased for a specific period of time and then renewed by the DHCP server. If you are

experiencing trouble maintaining your lease from your service provider, configure the

SonicWALL to be “pingable” from the WAN. Some ISPs assume that if they cannot ping you,

you must not be online and the lease is not renewed by the DHCP server. Use the following

steps to solve this problem:

1.

Open your Web browser and enter the LAN IP address of the SonicWALL to access the

Management interface.

2.

Log into the Management interface using the user name and password you created during

configuration.

Other Troubleshooting Tips

Be sure you can connect from your computer directly to the cable modem and establish an

Internet connection. If you can do this with your computer, but not with the SonicWALL, record

all of your Network settings and check them against the information in the SonicWALL.

Erasing the Firmware

There can be instances when it is necessary to reset the SonicWALL to its factory clean state if

the following events happen to the appliance:

•

Administrator password is forgotten.

•

The firmware has become corrupt, and you cannot contact the Management Interface.

•

The test light comes on and stays on for more than a few minutes.

•

During the troubleshooting process, you must start from a “known” state.

Once the firmware is erased, new firmware must be loaded, and the SonicWALL must be

reconfigured.

The following procedure erases all settings and reverts the unit to the factory default state. It

is necessary to follow the initial configuration procedures detailed in this manual's QuickStart

SonicWALL Installation Guide Page 79

section to reconfigure the SonicWALL. If you need the firmware, download it from <http://

firmware.sonicwall.com> or load it from the CD included with the appliance. You can also

download firmware by logging into <http://www.mysonicwall.com> as a registered user.

Locating the Reset button on your SonicWALL Internet Security Appliance

SonicWALL SOHO3, PRO 100, TELE3, SOHO 10, SOHO 50, XPRS, SOHO Telecommuter, PRO

200, PRO 300, and newer SonicWALL DMZ models use the small recessed button on the back

of the unit for this procedure. If your SonicWALL DMZ unit has a square reset button that is not

recessed on the back of the unit, follow the procedure below to locate the blue reset button.

SonicWALL 10 and 50 models, SonicWALL Plus, and older SonicWALL DMZ models have a blue

reset button inside. Open the SonicWALL unit by unscrewing the screws on the bottom and

gently pulling the top cover off. (The front and back panels remain in place.) Locate the blue

button towards the front between the Power, Test, and WAN LEDs.

If your SonicWALL DMZ unit has a circular reset button that is recessed in the back of the unit,

then it’s an older DMZ model and you should follow the procedure for locating the reset button

inside the unit.

Erasing the Firmware for all Models

1.

Turn off the SonicWALL and disconnect all cables to the network.

2.

Locate the recessed Reset Switch on the back panel of the SonicWALL.

3.

Press and hold the Reset Switch and then apply power to the SonicWALL. Once the

Test LED starts to flash, let go of the Reset Switch.

The Test LED flashes for approximately 90 seconds while the firmware is erased. After

completing the diagnostic sequence, the Test LED stays lit, indicating that the firmware has

been erased. It is normal for the Test LED to stay lit after erasing the firmware. It does not go

off until the firmware is installed and loaded into memory by the automatic restart.

4.

Log back into the SonicWALL at the default IP address, "http://192.168.168.168".

Make sure that the Management Station's IP address is in the same subnet as the Son-

icWALL--for example, "192.168.168.200".

5.

The SonicWALL Management Interface displays a message stating that the firmware

has been erased. Click

Browse

to locate the SonicWALL firmware file on the Manage-

ment Station hard drive. Or upload the firmware file that is located on the SonicWALL

Companion CD.

6.

Reconfigure the SonicWALL as described in Chapter 2 of this guide.
