PORT Red If the Expansion Hub was disconnected
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 AdminBrowser’s ‘Clear All
Disconnect Status’ command to clear
all disconnect states to no connect
states.
The Expansion Hub was previously
connected, but it is not currently
connected; 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
AdminBrowser’s “Clear All Disconnect
Status” command.

Use AdminBrowser to determine the
exact cause of the Main Hub’s faults.
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 disconnect
the offending Expansion Hub initially to
obtain status from the rest of the system,
then connect the Expansion Hub and
resolve the communication problem.
PORT Red The Expansion Hub or connected RAU
reports a fault condition; use
AdminBrowser to determine the exact
cause of the Expansion Hub and RAU’s
faults.
Degraded performance or unit may be
off-line.
Depends on fault condition.
