Removal/Replacement Procedures
This chapter provides the removaland replacement proceduresfor most fieldreplaceable units
(FRUs). The procedures included in this manual are based on the recommended spares listed
in Table 5–1. The removal/replacement procedures provided are intended for use by qualified
technicians familiar with the drive. Each FRU is listed in Table 5–1 with its part number and,
if applicable, the title of the associated removal/replacement procedure and section where the
procedure is located.
When performing certain removal/replacement procedures, an adjustment procedure may be
needed to complete the replacement and a service aid may need to be performed to verify
that the replaced part is operating properly. Adjustment procedures are provided in Chapter
6 and service aids are described in Chapter 4.
WARNING
Before performing any removal or replacement procedures, ensure the tape
drive is powered OFF and the power cord is disconnected from the wall
outlet.
CAUTION
Once the drive is installed and running on a host system, removing ac power
from the drive (disconnecting power cord or setting ac power switch to off
(0)) can interrupt the normal operation of the system. Always shut down the
system before removing or connecting the TSZ07 to the SCSI bus, or while
preparing to replace a FRU.
