Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ユーザーズマニュアル

After you clear the shutdown state and reset the affected module, each port is brought offline 
and then back online before the module and the entire system is operational. 

If you experience an I/O module failure, use the following troubleshooting methods when you 
can bring the switch offline to solve or learn more about the problem:

Restarting the I/O module—Use the 

disable slot

 <slot>

 command followed by the 

enable slot

 <slot>

 command to restart the offending I/O module. By issuing these 

commands, the I/O module and its associated fail counter is reset. If the module does not 
restart, or you continue to experience I/O module failure, contact NETGEAR Technical 
Support.

Running diagnostics—Use the 

run diagnostics

 normal <slot>

 command to run 

diagnostics on the offending I/O module to ensure that you are not experiencing a 
hardware issue. If the module continues to enter the failed state, contact NETGEAR 
Technical Support. For more information about switch diagnostics, see 

If you experience an MSM/MM failure, contact NETGEAR Technical Support.
