Chapter 13: MTS Troubleshooting
Corrective Action
- Check if power supply switch is ON
- Verify power to the Site Controller cabling
- Check LEDs on PS (power supply)
- Replace PS (power supply)
If it is not booting / startup phase:
- Check the Standby Site Controller cabling,
connections to all units
- Check its status of ports and links
- Check status of appropriate frus: atcc, dpm,
psu (see can bus problems)
- Check ports and links state: port, in case of
problems check all cabling connections
- Check the status of IAC inputs status
- Check site link failure: .sitelink, status sc
- Check cabling, replace cabling if needed
- Replace FRU
- Check if GPS antenna is connected
- Check status sri
Canbus problems:
- Check canbus registration table: can
check_mapping*
- Verify the registration table with existing
FRU configuration.
- If units not present exist, check cabling
(caution: all units connected in series). try to
reset or reboot can reset*, can reboot*
- If didn't help may try to upgrade units
software or replace faulty unit
- If units not present doesn't exist – remove
entry from registration table
- If track id not mapped probably registration
table not properly updated
Error detected:
- Get appropriate unit status / alarm to see
details about possible alarm cause
- If cause is in wrong configuration (wrong
VSWR thresholds or fans not started) modify
it. If alarms are considerably higher than
the default values, investigate a potential
hardware issue with the ATCC.
- If FRU doesn't work properly, try to upgrade
