including cabling

or Media Translator) between
Information Center and Switch
- loss of Server connection to
network
Verification
Determine if problem is on the device
or the network by observing
functionality
- check whether Clients are receiving
data from Information Center.
- determine if other Information
Centers are in local database mode
