AXIS 2420 User’s Manual Updating the Firmware 63

Appendix E - Updating the Firmware
The AXIS 2420 camera firmware is stored in Flash memory. This memory is provid ed by a
silicon chip that, just like any other ROM device, retain s data content even after power is
removed. Flash memory is unique because it allows its data to be erased and re-written.
This means that you can install firmware updates for your AXIS 2420 as soon as they
become available - without having to replace any parts. New firmware can be simply
loaded into the AXIS 2420 over the network.

Obtaining Updated Firmware

The latest version of the AXIS 2420 camera firmware is available free of charg e from the
Axis website at www.axis.com or from your local distribu tor.

The AXIS 2420 Flash memory is upgraded over the networ k using FTP. See the detailed
instructions supplied with each new firmware release.
Important!
• Always read the instructions available with each new release, prior to ugrading.
• Upgrading normally takes at least 30 seconds and up to 10 minutes, although it can take longer.
After starting the process, you should always wait at least 20 minutes before power cycling the AXIS
2420 - even if you suspect the upgrade procedure has failed.
• In controlled environments, flash memory upgrades provide a very safe method for updating firm-

rectly. Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the
user.
