b. To attach a type 4939 expansion enclosure to a type 2076 expansion
enclosure, continue at Step 7.
c. To attach the control enclosure to a type 2076 expansion enclosure,
continue at Step 12.
4. Connect the other end of the SAS cables in the control enclosure to port 1 in
each canister of the first expansion enclosure. Each type 4939 expansion
enclosure canister has 2 SAS ports. Port 1 is located on the left and port 2 is
on the right.
5. If you are attaching an additional type 4939 expansion enclosure, connect SAS
cables from the first expansion enclosure canisters port 2 to the second
expansion enclosure canisters port 1 as shown in Figure 13 on page 19.
Note: To avoid problems, port 2 of the canisters in the last expansion
enclosure should have no cables attached.
6. If you have installed type 2076 expansion enclosures, continue at Step 7.
Otherwise, the SAS cabling is complete. Go to Step 15.
7. Connect a SAS cable from port 2 of the left canister of the type 4939 expansion
enclosure to port 1 of the upper canister of the first type 2076 expansion
enclosure. Each type 2076 expansion enclosure canister has two SAS ports;
two on the upper canister and two on the lower canister that is installed
upside down.
8. Connect a SAS cable from port 2 of the right canister of the type 4939
expansion enclosure to port 1 of the lower canister of the first type 2076
expansion enclosure.
9. If you are attaching an additional type 2076 expansion enclosure, connect a
SAS cable from the first expansion enclosure upper canister port 2 to the
second expansion enclosure upper canister port 1 as shown in Figure 13 on
page 19.
