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).
If the Expansion Hub is to be
removed from service permanently,
then use AdminManager’s ‘Clear All
Disconnect Status’ command to
clear all disconnect states to no con-
nect states. The Main Hub’s port
LEDs should change to Off/Off.
Expansion Hub was previously con-
nected, but it is not currently con-
nected; Expansion Hub cable
disconnect.
AdminManager will clear all discon-
nects caused by installation as part of
the clean-up process. After installation,
power cycle the Main Hub or use
AdminManager’s “Clear All Discon-
nect Status” command.
