Serial-attached SCSI (SAS) ports. Each canister has two SAS ports for
connecting to optional expansion enclosures.
Control enclosure support rails
The left and right control enclosure support rails (Figure 3) are designed
specifically for installation of a control enclosure.
v
The ledge on the inside of the rails supports the entire length of a control
enclosure.
v At the rear end of the control enclosure support rail, the top edge curves over to
capture the top edge of an inserted control enclosure. This prevents the installed
control enclosure bouncing when the rack is subjected to quake or vibration.
v
The control enclosure support rails adjust to fit racks from 685 mm to 765 mm
deep, measured between the front and rear rack rails.
Expansion enclosure components
Figure 4 on page 8 shows the rear view of an expansion enclosure and identifies
