SF7x Storage Enclosure FRU Replacement 6–9
6.1.2 Warm Swap and Repair Procedures
Before you start the removal and replacement procedures, you must
obtain all necessary parameters from the device to be replaced, or
operating system data structures. If you have not done this, refer back to
Section 6.1.1.
• Check that the parameters you obtained from the preceding steps are
accurately recorded on the DSSI Configuration Sheet for this unit.
Configuration sheets should be in the Site Management Guide . Make
any necessary corrections to the recorded information.
• If the Fault LED on the front of an OCP is lit, press the Fault button
and record the fault code. This code corresponds to the failed FRU of
the disk ISE, as seen in Table 6–1.

To remove the disk ISE from the storage enclosure:
1. At the system console, dismount the faulty disk ISE through the VMS
operating system. For example:
>> DISMOUNT $1$DIA21
2. Access the front of the storage enclosure by opening the cabinet doors.
3. Take the disk ISE off-line by pressing Ready on the operator control
panel (OCP) for the disk ISE being removed (Figure 6–2).
4. At the bottom front of the storage enclosure, set the drive dc power
switch to off (Figure 6–2). The switch LED should go out to indicate
that power has been removed from the disk ISEs. If the LED does not
go out, suspect a faulty switch.
5. Remove the front or rear cover over the drive position. Loosen the two
captive screws in the upper corners of the cover. Lift the cover off and
clear from the enclosure.
