Alarm:24
Wireless
communication may
be disabled the next
time the system is
powered up.
This message occurs only at the end of System
Reevaluation. It could be due to one of the
following:
• The system has fewer than four cells.
• The system is brought online before all Base
Stations are properly connected.
• There is a break in the power or TCM
connections to some Base Stations.
Note: Do not attempt to solve the problem by
repowering.
1. Check that the correct number of Base
Stations have been connected and that the
system recognizes the Base Stations (see
page 145). If all the Base Stations you
expected to see are not showing or they are in
a failed state, check
• that the TCM wiring of Base Stations is correct
• that there is power to the Base Stations and
RPIs or plug-top power supplies
• that the location and number of Base Stations
are correct
• that any Base Station Modules are properly
connected to the expansion ports
2. Once you have corrected the problem run a
System Reevaluation (see “System
Reevaluation” on page 140).
If you continue to experience
Alarm:24
after
running System Reevaluation, you have either
insufficient Base Stations or an insufficient
deployment.
