Serviceability

The system is designed for service 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 mean time to repair.
The 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.
Remove cover
Remove and replace hard disk drive
Remove and replace 5 ¼ peripheral device
Remove and replace power supply
Remove and replace drive cage fan
