Error: "976 SRV NET SW"

Error: "976 SRV NET SW"

The problems listed are due to NVRAM corruption on the network card. The x.20.30 firmware was developed in response to these issues.

Error: "Network 54 Error" intermittently
Error: "976 SRV NET SW"
Printer network settings (TCP/IP address, LAA, host name) changed frequently
IP address on network card changes frequently
Host name or LAA changes randomly
'Garbage' characters print out on the network settings page
Unable to communicate with printer across the network
Printer loses network settings
Printer "drops off the network" or will not accept print jobs

Printer Loses Network Settings

Customers experiencing some or all of these problems should upgrade to the x.20.30 firmware level. When a network card is upgraded to x.20.30, all network settings are automatically moved to an unaffected sector of the NVRAM. Note: Because the move is automatic, no network settings (TCP/IP address, host name etc) will be lost.

To update the network card:

Download the latest version of firmware for your print server:
  • Click here and select  Drivers & Downloads.
  • Select  Network Adapters from the list of products and then choose your adapter.
  • Click on Firmware and then download the latest version for your adapter.
  • Follow the directions in the README.TXT document to extract and send the firmware to the network card.
  • If the issues persist after the update, an NVRAM reset may need to be performed. Follow the instructions for resetting the NVRAM below. Warning! The NVRAM reset will erase ALL network settings (including the TCP/IP address) and restore them to the default values. Follow this procedure only as a last-case option. Lexmark is not responsible for any unintended outcome from the procedure. If you have any questions about resetting the NVRAM it or are at all uncomfortable with carrying out this procedure, we suggest you contact your local Technical Support Center for assistance.
  •  If the NVRAM reset does not resolve the issue, please contact the Lexmark Technical Support line.
  • To reset the NVRAM on an INTERNAL network card:

  • Print a Network Settings Page:

  • When the LEDs indicate a binary three, press the Menu button to enter the NVRAM menu. A binary three pattern is indicated when the third and fourth LEDs are lit up.
  • When the light indicates a binary two, press the Menu button to reinitialize the NVRAM. A binary two pattern is indicated when the third LED is lit up. The adapter should then return to a ready state, with the LEDs scanning across the adapter from left to right and from right to left. This indicates that the NVRAM on the adapter has been reset and must be configured for your network.
