This is normal if the switch is a Member in
a stack.
If operating as a standalone switch or as
the Manager in a stack, enable the port.
Refer to the SecureStack A2
Configuration Guide for instructions to
enable/disable ports.
Verify that all network connections
between the network management station
and the device are valid and operating.
If the problem continues, contact
Enterasys Networks for technical support.
Verify that Spanning Tree is enabled.
Refer to the SecureStack A2
Configuration Guide for the instructions to
set the type of STA.
Review the network design and delete
unnecessary loops.
If the problem continues, contact
Enterasys Networks for technical support.
Reenter the lost parameters as
necessary. Refer to the SecureStack A2
Configuration Guide for the instructions to
configure the SecureStack A2 using CLI
commands.
If the problem continues, contact
Enterasys Networks for technical support.
Execute the "save config" command, and
wait for the prompt to come back before
Powering the switch off.
Executing the "reset" command
