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 items listed
in
Tabl e 1.
Table 1 Items to Check
If you experience any problems operating the Switch,
refer to
“Troubleshooting” on page 73.
Cabling Check that all external cabling connections
are secure and that no cables are pulled
taut.
Cooling fan Where possible, check that the cooling fan
is operating by listening to the unit. The fan
is fitted near to the front right hand side of
the unit (when viewed from the front).
