Introduction
This section describes system maintenance tools and procedures to guide you in identifying
Mini-Carrier Remote (MCR) faults, locating defective equipment, correcting problems by fixing
or replacing defective equipment, and verifying the operation of MCR after corrections or
replacements have been made.
Repair and replacement
The following are critical points for dealing with card failure:
• The MCR circuit packs are field replaceable only. With the exception of daughterboard
replacements, they are not to be serviced in the field.
• In the event of failure, the circuit packs must be returned for repair or disposal.
• All ESAM configuration data are stored on the RMI. If the user replaces the RMI for any
reason, all data set with the SET ESAM command, and all commands on the ESAM setup
menu, must be reconfigured.
• All SPAN configuration data are stored on the LMI. If the user replaces the LMI for any
reason, all values set with the SET SPAN command, and all commands on the Span setup
menu, must be reconfigured
