Installing a Power Supply Module

supply module into the chassis until it is fully seated. See Figure 3-1.
2 Rotate the power-supply module handle upward until its release tab snaps securely into
place.

Fan Modules
Your system contains up to four system fans (two sets of redundant fans) contained in two
hot-pluggable fan modules. Each fan module has system fan indicators on its back panel
that identify the status of each of its system fans. See Figure 1-7.
