AXIS 2411 Admin Manual Updating the Firmware

Appendix C - Updating the Firmware
The AXIS 2411 firmware is stored in Flash memory. This memory is provided by a silicon chip that,
just like any other ROM device, retains data content even after power is removed. Flash memory is
unique because it allows its data to be erased and re-written. This means you can install firmware
updates for your AXIS 2411 as they become available - without having to replace any parts. New
firmware can be simply loaded into the AXIS 2411 over the network.
Obtaining Updated firmware
The latest version of the AXIS 2411 firmware is available free of charge from the Axis website at
www.axis.com or from your local distributor.
Updating the firmware
The AXIS 2411 Flash memory is updated over the network using FTP. See the detailed
instructions supplied with each new firmware release.
Important!
• Always read the upgrade instructions available with each new release, before updating the firmware.
• Upgrading normally takes between 30 seconds and 10 minutes, although it can take longer. After
starting the process, you should always
wait at least 20 minutes before power-cycling the AXIS 2411
- even if you suspect the procedure has failed.
• In controlled environments, flash memory updates provide a very safe way of updating the firmware.
However, flash products can become damaged if the update is not performed correctly. Your dealer
reserves the right to charge for any repair attributable to faulty updating by the user.
