locations.
v 1 LEDs
v 2 SAS ports
Each canister has two SAS ports that are numbered 1 on the left and 2 on the right.
Port 1 is used to connect to a SAS expansion port on a node canister or port 2 of
another expansion canister.
The left and right expansion enclosure support rails (Figure 6 on page 9) are
designed specifically for installation of an expansion enclosure.
v The ledge on the inside of each rail supports the entire length of an expansion
enclosure.
v The expansion enclosure support rails capture the left and right rear edges of an
inserted expansion enclosure. This prevents the installed control enclosure
bouncing when the rack is subjected to quake or vibration.
v The expansion enclosure support rails adjust to fit racks from 595 mm to 755
mm deep, measured between the front and rear rack rails.
