Check the Main Hub Functionality LEDs
The unit functionality LEDs (POWER and SYNC) should be green. If not, cycle the
power to reset the Main Hub.
Check the Main Hub MMF Port LEDs
The MMF port LEDs (LINK STATUS and SYNC) should be red. This indicates that the
other end of the MMF cable is not yet connected to the Expansion Hub ports.
NOTE: Refer to Section 10 for troubleshooting LEDs.
NOTE: You do not have to use all of the MMF ports on the Main Hub. Unused ports
do not need to be terminated. Free ports can be used for future growth and to manage
changes in the in-building system.
