SF7x Storage Enclosure FRU Replacement
6.4 Replacing the Fan Assembly
Use the following steps to remove and replace the fan assembly (PN
70–24440–01):
1. At the system console, dismount
all
the ISEs on that bus.
2. Access the storage enclosure by opening the cabinet doors.
3. Take the disk ISEs in the storage enclosure off-line:
a. Press and release all Ready buttons on the OCP (Figure 6–2).
Wait for the Ready LEDs to go out.
b. At the front of the storage enclosure, set the drive dc power
switches to
off
(Figure 6–2). The switch element LEDs should go
out to indicate that power has been removed from the disk ISE. If
any LED does not go out, suspect a faulty switch.
CAUTION
Wear an ESD grounding strap at all times while handling the
storage enclosure or any of its FRUs.
4. Remove the OCP—grasp it firmly and pull it straight out. Do not pry;
the panel comes free with a straight pull.
5. At the rear of the enclosure, ensure that the DSSI interconnect cables
can be extended up to 3 feet.
WARNING
Take care when accessing the internal components of the
inner assembly. A stop mechanism in the chassis locks
the inner assembly at a point that allows access to the fan
assembly. This stop mechanism locks the chassis so that the
inner assembly is over three-quarters of the way out of the
chassis. If you release this stop, nothing prevents the inner
assembly from being pulled completely free of the extrusion
tube.
6. Loosen the four captive hex-head screws in each corner of the storage
enclosure.
7. From the rear, push the inner assembly out of the extrusion tube until
it latches at a position just past the top of the fan assembly.
8. Disconnect fan connector J6 from the transition-termination module
(Figure 6–12). The fan cable is captive to the fan.
