Chapter 13: MTS Troubleshooting
Corrective Action
• Check also if the IP suffix matches BR
Cabinet ID/Position ID combination,
for example: 10.0.253.cp where c = 1
(Cabinet ID) and p = 2 (Position ID) give
us 10.0.253.12. Use the command: boot1>
spr br_id
• reset BR
• check logs through SC
• verify proper cabinet/position by executing
get cabinet, get position MMI commands
• check BR IP addresses by executing get
ipconfig MMI command
• check for alarm conditions by executing
get alarms MMI command or by test
application (PA temperature alarm, lock
and ref alarms, all recievers failed, PA
VSWR, alarm...)
• check the Power Amplifier by executing
get pa_status MMI command (check
parameters: fwd power, frequencies)
• start test application and check for current
alarms by executing test application
command: alarms –ofault_hndlr ;
check TX (transmitter) and RX (receiver)
frequency by executing freq –otx_all, freq
–orx_all test application commands
• check reference signal from SC link
• reset BR
• replace BR
• check cabling to Site Controller
• check Site Controller status
• if ethernet link present check proper IP
address by executing get ipconfig MMI
command
• check Site Controller IP address
• check connection to the Site Controller
