Cisco Cisco FastHub 412M 10 100 Repeater

The delete nvram command only resets the NVRAM of the M1 hub. If an M2 hub is connected to 
the stack, the contents of the M2 hub NVRAM are immediately copied to the NVRAM of the M1 
hub. To ensure that you reset the NVRAM of a FastHub 400, use one of these methods:

To clear the NVRAM of the M1 hub, disconnect the stack cable between the M1 hub and the 
M2 hub, connect a console cable to the M1 hub, and use the delete nvram command.

To clear the NVRAM of the M2 hub, disconnect the stack cable between the M1 hub and the 
M2 hub, connect a console cable to the M2 hub, and use the delete nvram command.

You must power down the stack before resetting either or both management hubs. To do this:

Disconnect the stacking cable from the management hubs that you want to reset.

Connect the hub to a management station.

Power on the hub, and access the command-line interface (CLI).

See the online FastHub 400 10/100 Series Command Reference for information about accessing 
the CLI. See the 

 section of this document for information about 

locating this document through Cisco.com.

Use the CLI delete nvram command to reset either or both management hubs to their default 
values. 

See the online reference FastHub 400 10/100 Series Command Reference for more information 
about this command.

The management hub that is powered on first becomes the new M1 hub in the stack because by 
default, the hub with the longest up time is the M1 hub. 

If you delete the NVRAM configuration settings for one management hub and not the other, be sure to 
first power on the management hub with the deleted configuration. This prevents the redundant 
management hub from copying its saved configuration to the hub whose configuration you just deleted.
