Connecting the 7133 Model T40 to the Power Source 1. Refer to Figure 12. 1 2 4 3 4 Figure 12. Plugging In the Power Cables 2. Ensure that the two short cables 3 are plugged into the power supply assemblies. 3. The 7133 Model T40 is supplied with two power cables and plugs that are suitable for your country. Plug the power cables into the sockets 1 and 2 . | | | | | | 4.
6. Refer to Figure 13. 1 Figure 13. Power Switch of the Remote-Power-On Control Unit 7. Ensure that the power switch 1 of the remote-power-on control unit is set to | (on). 8. If the power to the using system is switched off, switch it on (see the using-system Operator Guide, Installation and Service Guide, or equivalent).
9. Refer to Figure 14. 3 1 2 4 5 6 Figure 14. Checking the Lights 10. Plug the power cable into a mainline electrical power outlet. If the power outlet has a switch, switch it on. 11. Check whether the 7133 Power light 1 comes on. If it comes on, go to step 15 on page 24. If it does not come on go to: v Step 12 if the 7133 has a remote-power-on control unit. v Step 13 if the 7133 does not have a remote-power-on control unit. 12.
14. If the 7133 Power light comes on, go to step 15. If the light still does not come on, go to “MAP 2010: 7133 – START” in the 7133 Models D40 and T40 Serial Disk Systems: Service Guide if you are qualified technically to do so. Otherwise, call your service representative. 15.
v If the ID display is showing alternating IDs, go to step 18. 18. If a failure occurs in the 7133, the ID display shows an error ID alternating with the enclosure ID. Table 1 shows these error IDs. Table 1.
If the error ID is HOT, the internal dc power switches on automatically after the temperature has decreased and has remained more than 5°C below the critical temperature for 15 minutes. a. Find the displayed error ID in Table 1 on page 25, and note its related SRN. b. Go to “Service Request Numbers” in the 7133 Models D40 and T40 Serial Disk Systems: Service Guide if you are qualified technically to do so. Otherwise, call your service representative. 19.
Appendix A. Example Configurations The diagrams in this appendix show some example configurations for the 7133. All the configurations that are shown here are the simplest and provide the best ease of use. If performance or availability are particularly important to the customer, however, more complex cabling might provide a better solution; consult your marketing representative for more details. Under the standard SSA rules, you can mix any compatible SSA devices in a particular SSA loop.
No improvement in performance is gained if the disk drive modules are moved to other slots and connected in more than one loop. The cables are described in “SSA Cables” on page 38. The internal connections of Model T40 are shown in Note 4b on page 10. For information about the rules for SSA loops, see Note 4a on page 9.
Larger Configurations Four more disk drive modules can be added to the base configuration in one loop. For a balanced subsystem, however, it is recommended that the two groups of disk drive modules be connected in two separate loops, each of which is connected to a separate pair of connectors on the SSA attachment (see Figure 16). Using system A1 A2 2 1 B1 B2 2 2 2 7133 unit 4 8 7 6 5 4 1 3 2 1 5 8 16 13 9 12 Figure 16.
Largest Configurations with One 7133 All 16 disk drive modules in a full 7133 can be connected in one loop. For a balanced subsystem, however, it is recommended that two groups of eight disk drive modules be connected in two separate loops, each of which is connected to a separate pair of connectors on the SSA attachment (see Figure 17). Using system A1 A2 2 1 B1 B2 2 2 2 7133 unit 4 8 7 6 5 4 1 3 2 1 5 8 16 13 9 10 11 12 9 13 14 15 16 12 Figure 17.
Multiple-Unit Configurations An SSA subsystem can include disk drive modules that are installed in more than one 7133. You can connect up to 48 disk drive modules in one loop, and up to 96 disk drive modules to one SSA attachment. In larger subsystems, unless the work load of the system has special requirements, best performance is obtained if you connect equal numbers of disk drive modules to the loops that are available. In the following example, 32 disk drive modules are connected to an SSA attachment.

Preventing the Isolation of Disk Drives in Higher-Availability Configurations If a loop contains four SSA attachments, with two attachments in each of two using systems, disk drive modules become isolated if they are connected between the two SSA attachments of one using system, and both those attachments fail, or are held reset, but remain powered on.
If, however, disk drive modules are connected into the link between two SSA attachments that are in the same using system, those disk drive modules become isolated both SSA attachments fail, or are held reset, but remain powered on (see also “Bypass Note” on page 36). In Figure 23, disk drive modules 13 through 16 have been connected between the SSA attachments of using system 1.

If you are also connecting SSA cables, but have not done so yet, go to “Connecting SSA Cables to the SSA Adapter” on page 45. Otherwise, go to “Checking Whether a Remote-Power-On-Control Unit is Present” on page 19. Connecting Fibre Optic Cables for Multi-Mode Operations 1. Refer to Figure 35.
Note: The fibre optic cables have: v An inner connector with an alignment lug that engages a slot in the connector of the uniter | | | | v An outer, bayonet (push-and-twist) connector that locks the cable to the uniter. To connect a fibre optic cable: a. Push it into the uniter. As you push the cable, use a twisting motion to ensure that the alignment lug engages the slot in the uniter. | | b. Fasten the uniter to the multi-mode conditioner. 8.
Verifying the Installation | | 1. If the 7133 is going to be used as an SSA RAID subsystem, go to the user or service information for your SSA adapter for information about how to configure RAID arrays. When you have configured the RAID arrays, return here and go to step 2. If the 7133 is not going to be used as an SSA RAID subsystem, go to step 2. | | 2. Use the SSA Remote Systems Management configurator to check whether the SSA loops that you have configured on the adapter are complete and correct.
| | | If any light is off, go to “MAP 2330: 7133–Optical Extender” in the 7133 Models D40 and T40 Serial Disk Systems: Service Guide if you are qualified technically to do so. Otherwise, call your service representative. 8. If you have done the previous steps as part of the initial installation of the complete system, return to the system installation instructions.
