No.

Cause for Switchover Disabled

 

Troubleshooting Steps

 

 

 

 

1

The standby system is not

Lit in red

The standby system has failed. Replace the standby system BCU, CSU,

 

activated.

 

or MSU board.

 

Check the STATUS LED on the

 

 

 

OFF or lit in

Board is not activated. Execute the inactivate standby/

 

standby system.

 

 

orange

activate standby command on the active system to activate the

 

 

 

standby system.

 

 

Blinking in

The standby system is being activated. Wait a while until lit in green.

 

 

green

 

 

 

 

 

 

 

Lit in green

The standby system is already activated, and another cause may exist. See

 

 

 

other items.

 

 

 

 

2

The standby system is not

fault

Any one of the followings is applied:

 

prepared for switch.

 

• Activation of the standby system failed.

 

Login the active system, and use

 

• Inhibited combination of the active system board and standby system

 

the show system command to

 

board is adopted. Eliminate the cause for failure, and restart the system.

 

check the status of the standby

 

• Unavailable configuration has been set. Review settings in the

 

system.

 

 

 

configuration.

 

 

 

 

 

 

Otherwise, see No. 1.

 

 

 

 

 

 

inactive

Activation of the standby system is suppressed. Execute the activate

 

 

 

standby command to activate the standby system.

 

 

notconnect

The standby system is not installed. Install the standby system, then

 

 

 

execute the activate standby command to activate the standby

 

 

 

system.

 

 

initialize

Activation of the standby system is not completed. Wait until activation

 

 

 

completes.

3

Modifying configuration.

During modifying configuration, switchover by the operation command is suppressed.

 

If the operation command is used

Execute configuration command status on the active system to make all users working

 

to switchover, command

with configuration log out, then switch over the system by the operation command.

 

execution fails.
