n During attempts to isolate and resolve system troubles, the System
Module must be shifted into various positions to allow access to
certain areas. When handling the System Module, care should be ^
taken not to damage its components in any way. If the System j j
Module contains a Hard Disk Unit (HDU), extra care should be —
taken because the HDU is very sensitive to sudden shocks. The
HDU heads should be parked with the "SHIP" command before
moving the unit. You must never lift the System Module for any
reason if power is present on the HDU.
