Technical data

For information on troubleshooting strategy, error analysis, and
diagnostics, refer to the TLZ04 tape drive service manual.
Use the following instructions to a TLZ04 tape drive. Refer to Figure 3–11.
CAUTION: Static electricity can damage integrated circuits. Use the wrist
strap and antistatic mat found in the Antistatic Kit (PN 29–26246) when
you work with the internal parts of a computer system.
Handle the tape drive with care. Dropping or bumping it can damage the
drive. Carry or hold the drive by its metal brackets to avoid damaging the
drive.
1. Loosen the single captive Phillips screw that secures the TLZ04 front
panel (Figure 3–11A).
2. Separate the TLZ04 front panel from the enclosure, being careful of the
ID cable, which is connected to the TLZ04 front panel.
NOTE: If the cause of the drive failure is undetermined, inspect the
connection of the ID cable and the TLZ04 front panel. The cable may
not be connected securely, or the cable or connector is defective.
If the front panel appears to be the problem, refer to Section 3.5.2.2
for instructions on replacing the TLZ04 front panel. To replace the ID
cable, continue removing the tape drive and then refer to Section 3.5.2.1
for instructions on replacing ID cable (PN 17–01936–02).
3. Unplug the remote ID cable from the TLZ04 front panel and set the
front panel aside (Figure 3–11B).
4. Loosen the upper and lower captive screws that hold the drive in place
(Figure 3–11C).
5. Using the upper and lower finger cutouts on the drive bracketry,
carefully pull the drive out of its backplane connector and slide the
drive out of the enclosure. Support the weight of the drive at the lower
bracket as the drive clears the enclosure (Figure 3–11C).
NOTE: If the cause of the drive failure is undetermined, inspect the
condition of the interface card and its associated cables and cable
connections. Refer to Section 3.5.2.3 for instructions on replacing the
interface card assembly (PN 54–20136–03).
