pation. Plan the FRU to connector or connector to FRU airflow, as
required.

Stacked Installation (Optional)

system on top should be installed without its floor, in order to allow easier
access to FRUs. To remove the floor, unscrew three screws on each side of
the system.
*SLIDE THE FRONT PANEL TOWARDS THE SWITCH,
AND TIGHTEN THE TWO CAPTIVE SCREWS.
