AdminBrowser clears all disconnects

If the Expansion Hub was disconnected
accidentally, re-connect th
e cables. The
LEDs should change to Green/Red, and
then Green/Green, after 20 seconds (if
the Main Hub band has been
programmed).
When the Expansion Hub is to be
rem
o
ved from service permanently,
use the AdminBrowser Clear All
Disconnect Status command to clear
all disconnect states.

Lost communication with Expansion
Hub;
could be a problem with the Expansion
Hub or the fiber cable.
The Expansion Hub communication
problems delay Main Hub’s response to
AdminBrowser commands, resulting
in
command time-outs. You can initially
disconnect the offending Expansion Hub
to obtain status from the rest of the
system, then reconnect the Expansion
Hub and resolve the communication
problem.
Use AdminBrowser to determine the
ex
ac
t cause of the Main Hub’s faults.
Port Red Unit may have degraded performance or
go off-line, which is dependent on the
fault condition.
The Expansion Hub or connected RAU
reports a fault
condition; use
AdminBrowser to determine the exact
cause of the corresponding unit’s
faults.
