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
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
The SonicWALL TELE3 SP uses the small recessed button on the back of the unit for this
procedure.
Erasing the Firmware
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
SonicWALL, 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 Management
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.
