3.3 Faults and Warnings
The Main Hub monitors and reports changes in system performance to:
• Ensure that the fiber receivers, amplifiers, and IF/RF path in the Main Hub are
functioning properly.
• Ensure that Expansion Hubs and Remote Access Units are connected and function-
ing properly.
The Main Hub periodically queries attached Expansion Hubs and their Remote
Access Units for their status. Both faults and warnings are reported to a connected
PC/laptop that is running the AdminManager software or to the optional remote
OpsConsole. Only faults are indicated by LEDs.
