Drive bay numbering
• Drive bay numbering for four 1U nodes
In an 8-drive bay LFF drive configuration, drives are numbered from top to bottom in each box.
o Drives in the first box correspond to node 1.
o Drives in the second box correspond to node 2.
o Drives in the third box correspond to node 3.
o Drives in the fourth box correspond to node 4.
CAUTION: To prevent improper cooling and thermal damage, do not operate the chassis unless
all bays are populated with a component or a blank.
