Module Software Cannot be Upgraded
If your attempt to upgrade the software of a module fails, perform the following steps.
Procedure 35 Troubleshooting an unsuccessful software upgrade
1 Download the latest issue of the target release and the associated release notes.
2 Verify that the latest version of CNUT is installed.
3 Compare the files used in the failed attempt to the newly downloaded software.
4 Compare the procedure used in the failed attempt to the procedure in the newly
downloaded release notes.
5 If these comparisons reveal a difference, retry the upgrade, this time with the newer file
or newer procedure.
6 If, during attempts to upgrade the FPGA firmware, the following message is repeatable,
then request an RMA for the module:
Error code 6, unrecognized device
Module Functions Properly, Except Web Interface Became
Inaccessible
If a module continues to pass traffic and the SNMP interface to the module continues to function, but
the web interface to the module does not display, perform the following steps:
Procedure 36 Restoring web management GUI access
1 Enter telnet DottedIPAddress.
RESULT: A telnet session to the module is invoked.
2 At the Login prompt, enter root.
3 At the Password prompt, enter PasswordIfConfigured.
4 At the > prompt, enter reset.
RESULT: The web interface is accessible again and this telnet connection is closed.
Note
The module may also be rebooted via an SNMP-based NMS (Wireless
Manager, for example)
5 If the issue persists, turn off any SNMP-based network/radio monitoring software and
repeat steps 1-4.
