the rear of the enclosure.
b. Fit the slot on the top of the end cap over the tab on the chassis flange.
c. Rotate the end cap down until it snaps into place.

Connecting SAS cables to expansion enclosures
If you have installed expansion enclosures, you must connect them to a control
enclosure.
About this task
This task applies if you are installing one or more expansion enclosures. Each
control enclosure in the system can manage up to 19 expansion enclosures. A
system that contains two control enclosures can have up to 38 expansion
enclosures.
Note: When connecting SAS cables between enclosures, you must follow a list of
guidelines to ensure that your configuration is valid. Do not begin connecting the
cables until you have read “SAS cabling guidelines” on page 19.
Procedure
To install the cables, complete the following steps.
1. Using the supplied SAS cables, connect the control enclosure to the expansion
enclosure at rack position 1, as shown in Figure 14 on page 19.
a. Connect SAS port 4 of the left node canister in the control enclosure to SAS
port 1 of the left expansion canister in the first expansion enclosure.
b. Connect SAS port 4 of the right node canister in the control enclosure to
SAS port 1 of the right expansion canister in the first expansion enclosure.
