7.9 SDI Cable Removal and Installation
The SDI cables are routed from the rear bulkhead, over the top of the frame, and
down the sides to their respective drives. You actually install all the cables for a
port when you replace a single cable.
7.9.1 Removing an Enclosure SDI Cable
Use the following procedure to remove an enclosure SDI cable:
1. Take all of the drives in the enclosure off line and release the Run switches to
spin down the drives. Wait until all Ready lamps are off. (See Section 4.4.)
2. Remove power to the enclosure by turning off the Master On/Off switch and
disconnecting the power cord.
3. Remove the front and rear enclosure covers. For each cover, loosen the two
mounting screws (located in the upper corners of the cover), then lift the cover
up and outward to clear the enclosure.
4. Disconnect the SDI interface cables from the rear bulkhead of the enclosure.
(Refer to Figure 7–3.)
5. If the cabinet has a cabinet stabilizer foot installed, extend it. (Refer to
Figure 7–2.)
6. Remove the OCP. (See Section 7.3.)
7. Remove the power supply. (See Section 7.2.)
8. Remove all disk drives. (See Chapter 6.)
9. Loosen the four mounting screws in the corners of the enclosure frame and
slide the frame out of the chassis until it engages the chassis latch.
10. Double check the enclosure to verify there is nothing to prevent the frame
from being pulled out further, then each into the chassis and release the
chassis latch. (It may be necessary to push the frame back in about a quarter
inch for the latch to release.)
WARNING
Releasing the chassis latch allows the frame to be removed from the
chassis for this operation. Be prepared to take the weight of the frame
when it comes free of the chassis. Have a work space ready to put the
frame on after it is removed.
