13 Reliability, Serviceability, and Availability
13.1 Mean-Time-Between-Failure (MTBF)
MTBF data was being collected at the time of the generation of this specification. It will be provided
in a future revision of this specification or a Specification Update.
13.2 Serviceability
The system is designed to be serviced by qualified technical personnel only.
The desired Mean Time To Repair (MTTR) of the system is 30 minutes including diagnosis of the
system problem. To meet this goal, the system enclosure and hardware have been designed to
minimize the MTTR.
Following are the maximum times that a trained field service technician should take to perform the
listed system maintenance procedures, after diagnosis of the system.
