Red If the Expansion Hub was discon-
nected accidentally, re-connect the
cables. The LEDs should change to
Green/Red (then Green/Green, after
20 seconds, if the Main Hub band
has been programmed).
When the Expansion Hub is to be
removed from service permanently,
use AdminBrowsers ‘Clear All Dis-
connect Status’ command to clear all
disconnect states to no connect
states.
The Expansion Hub was previously
connected, but it is not currently con-
nected; the Expansion Hub uplink
cable disconnected.
AdminBrowser clears all disconnects
caused by installation as part of the
clean-up process. After installation,
power cycle the Main Hub or use
AdminBrowsers “Clear All Discon-
nect Status” command.

Use AdminBrowser to determine the

Lost communication with Expansion
Hub; could be Expansion Hub problem
or fiber cable problem.
The Expansion Hub communication
problems delay MH responses to
AdminBrowser commands, resulting in
command time-outs. You can discon-
nect the offending Expansion Hub ini-
tially to obtain status from the rest of
the system, then connect the Expansion
Hub and resolve the communication
problem.
