AXIS Q7401 - Troubleshooting
Troubleshooting
Checking the Firmware
Firmware is software that determines the functionality of the video encoders. One of your first actions when troubleshooting
a problem should be to check the current firmware version. The latest version may contain a correction that fixes your
particular problem. The current firmware version in your encoder can be seen on the page Setup > Basic Setup or under
About.
Upgrading the Firmware
When you upgrade your encoder with the latest firmware from the Axis Web site, your encoder receives the latest
functionality available. Always read the upgrade instructions and release notes available with each new release, before
updating the firmware.
Note:
P
reconfigured and customized settings are saved when the firmware is upgraded (providing the features are available
in the new firmware) although this is not guaranteed by Axis Communications. Always read the instructions and
release notes available with each new release, before upgrading the firmware.
1. Save the firmware file to your
computer. The latest version of the
firmware is available free of charge
from the Axis website at
www.axis.com/techsup
2. Go to Setup > System Options >
Maintenance in the encoder’s web
pages.
3. In the Upgrade Server section,
browse to the desired firmware file
on your computer. Click Upgrade.
Notes:
After starting the upgrade process,
always wait at le
ast 5-10 minutes
before restarting the encoder, even if you suspect the upgrade has failed.
Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the user.
The AXIS Camera Management software tool can be used for multiple upgrades. Please see the Axis website at
www.axis.com for more information.
Emergency Recovery Procedure
If power or the network connection to the encoder is lost during the upgrade, the process fails and the unit becomes
unresponsive. A flashing red Status LED indicates a failed upgrade. To recover the unit, follow the steps below. The serial
number is found on the label attached to the bottom of the encoder.
1. UNIX/Linux - From the command line, type the following:
arp -s <IP address of encoder> <serial number> temp
ping -s 408 <IP address of encoder>
Windows - From a command/DOS prompt, type the following:
arp -s <IP address of encoder> <serial number>
ping -l 408 -t <IP address of encoder>
2. If the unit does not reply within a few seconds, restart it and wait for a reply. Press CTRL+C to stop Ping.
3. Open a browser and type in the encoder’s IP address. In the page that appears, use the Browse button to select the
upgrade file to use, for example, axisq7401.bin. Then click the Load button to restart the upgrade process.
4. After the upgrade is complete (1-10 minutes), the unit automatically restarts and shows a steady green on the
Power and Status LEDs and flashing green or amber on the Network LED.
