Performing Spot Checks 
 
At frequent intervals, you should visually check the Switch. Regular checks can give you an early 
warning of a possible failure; any problems can then be attended to when there will be least 
effect on users. 3Com recommends periodically checking the cabling, including the power 
adapter and it’s connections.
