Radio cred req’d

Too many Base
Stations have been
connected to the
system. This
message will appear
only after a restart.

Excessive Base Stations have been connected
and the total number of available Radio Credits is
insufficient to accommodate all the radios.
Wireless communication remains disabled.
System Reevaluation may be disabled.

1. Verify the total and available number of radio

credits using the Administration Terminal.

2. Remove the excess Base Stations and restart

the system. To determine the number of
connected Base Stations to remove, subtract
the total number of radio credits from the total
number of connected Base Stations.
Remember that each Base Station has two
radios. See “Verifying Radio Credits” on
page 182. If you have increased the number of
Base Stations, you may need a new UTAM
Activation Code to cover the increase in radios.

Note:

If Radio Credits are required, then
reevaluation is disabled.
