Problem

Recommended Action

 

 

Interface Card fails

If one of the interface cards fails, use the Initialize Interface (INI) option in the System (SYS)

 

menu, Interface (IFC) option to reinitialize the interface. If this fails, you can try to restart

 

the whole unit again. If neither of these actions correct the problem you should contact a

 

3Com service person.

 

When handling modules, always use a wrist strap that is connected to a proper ground.

 

This prevents the module from being damaged by electrostatic discharge.

 

 

Fans do not rotate

If the fans do not work when the unit is powered up, the fan tray may not be inserted

 

properly. Unplug the power cord and reinsert the fan tray properly against the enclosure.
