RAID Array 3000 Controller Shelf
3–24 EK–SMCPQ–UG. C01
3.3.5 Cabling a Four Device Expansion Shelf Subsystem
(See Figures 3–10 and 3–13)
1. Ensure the physical installation phase of installing and securing shelf brack-
ets and shelves (including the UPS) has been accomplished and that the
shelves are secured within the shelf bracket the shelf lock provided.
2. Remove the device I/O module from the Controller Shelf and ensure the
switch positions of SCSI bus termination switch S4 are set as shown in Fig-
ure 3–9. Replace the module in the Controller Shelf.
3. Remove the personality I/O module from Device Expansion Shelf # 1 and
set SCSI bus termination switch S4 and SCSI bus address switch S3 on this
module as shown in Figure 3–13.
4. Remove the personality I/O modules from Device Expansion Shelves # 2, #
3, and # 4 and repeat step 3.
5. Connect the black ac power cords (supplied with the shelves) from the pri-
mary ac power source to the outside power supply on each shelf (see Figure
3–10).
6. Connect the gray power cables from the inside power supply on each shelf to
the power receptacles on the back of the UPS (ensure the UPS is connected
to a secondary ac source.
7. Connect the single-connector end of a Trilink adapter to the SCSI connector
on the personality module in Device Expansion Shelf # 1. Tighten the
screws on the adapter to ensure it is firmly seated.
8. Connect the single-connector end of a second Trilink adapter to the SCSI
connector on the personality module in Device Expansion Shelf # 2. Tighten
the screws on the adapter to ensure it is firmly seated.
9. Connect a 0.5-meter SCSI cable (BN37A-0E) from one connector on the
adapter connected to shelf # 1 to the top SCSI connector (device bus 1) on
the front of the Controller Shelf device I/O module.
10. Connect a second 0.5-meter SCSI cable (BN37A-0E) from the other con-
nector on the adapter connected to shelf # 1 to the SCSI connector on the
front of the personality I/O module on the Device Expansion Shelf # 3.
11. Connect a third 0.5-meter SCSI cable (BN37A-0E) from the one connector
on the adapter connected to shelf # 2 to the bottom SCSI connector (device
bus 0) on the front of the Controller Shelf device I/O module.
12. Connect a fourth 0.5-meter SCSI cable (BN37A-0E) from the other connec-
tor on the adapter connected to shelf # 2 to the SCSI connector on the front
of the personality I/O module on the Device Expansion Shelf # 4.
