IBM Storwize V3700 User Manual

Each canister has two SAS ports that are numbered 1 on the left and 2 on the right.
Port 1 is always used. Port 2 is used only if this is not the last enclosure in the
chain.
Expansion enclosure support rails
The left and right expansion enclosure support rails (Figure 6) 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.
