6–14 SF7x Storage Enclosure FRU Replacement
12. Use the following steps to remove and replace either disk ISE FRU.
CAUTION
• Static electricity can damage the circuitry on the drive
module. To avoid this problem, use an antistatic wrist
strap and grounded work surface, such as that in the
antistatic kit (PN 29–26246), when performing these steps.
• Handle the disk ISE with care. Excessive shock can
damage the HDA.
• Do not lose the screws or use screws other than the ones
that come with the device (PN 90–00039–07). Replacement
screws must be the same type and size (6/32 1/4" flathead)
or the HDA can be damaged.
a. Remove the four screws (using a #1 Phillips screwdriver) securing
the drive module to the HDA.
b. Carefully separate the drive module from the HDA, as shown in
Figure 6–5. Be sure to lift the drive module from the end with the
DSSI connector, separating the spindle motor from its socket on
the drive module. Take care not to stress the flex circuit.
NOTE
Figures 6–5 and 6–6 show a generic RF series disk ISE.
