NMC coordination must be accomplished prior to repeater being
switched to Local operating condition. This will prevent conflict-
ing actions between the NMC and on-site operator(s) and preclude
possible personal injury and/or equipment damage.
• Switch the repeater to the Local operating condition.
• Connect the PC to a repeater Ethernet (LAN) connector on the back panel
of the Controller (or to the SPU front panel RS-232 connector for CLI if an
active LAN connector is not a
vailable).
• View the SPU front panel indicators.
• Access GUI (or CLI screens).
• Use the Alarms and Status
GUI in conjunction with the SPU front panel
indications to help identify problem(s).
• Refer to Appendix D, “Alarm Descriptions, Causes, and Suggested
Responses”,
for procedures to correct problems.
• Access the GUI screens and enter changes as required.
• Remove and replace components if required.
• Major unit replacement requires parameter updating.
• Run repeater test on completion of troubleshooting/repair.
• Coordinate with the NMC and return repeater to the Remote operating
condition.
When working in the vicinity of fans (under repeater roof or
replacing air filter on repeater back door), power to fans must be
removed.
