Check for Power Supply Unit failure.
Verify power (voltage and polarity) on rear connector. If power is present and correct then
replace the Site Controller. Otherwise check for the Site Controller power supply cabling fault.
Ensure that the polarity of DC cable connection is correct, as it is reversed in comparison to MBTS.
If Overall Status = Active – <state> / <reason>, this is an indication that the Site Controller
is currently active, together with the site reference state and the reason for that state.
These states and reasons are explained in
If Overall Status = SC is going active – waiting for BRs, the Site Controller may
be unable to communicate with the BRs. Waiting for Site Controller configuration

Site Reference States - status sc
Explanation
The site reference is initializing - this is a transient state that may persist
for a few minutes at start up.
The site reference is fully trained to GPS - This is the highest level of
functionality.
The site reference is not working.
This is the first level of fallback - The site reference will continue to provide
its highest level of service in this state until the free run timer expires.
This is the second level fallback - The site reference is providing service
however any feature that needs sites to be synchronized may be impaired.
The site has been operating in its 2nd level fallback mode for too long (>
350 days) and should be disabled by the operator.
The site has been configured to operate in its 2nd level fallback mode (FNC)
to enable start-up without GPS.
