1. Remove all modules except the motherboards from the chassis and put them in a
safe place.
Refer to “Removing and Installing Modules” on page 23.
2. Using the Phillips No.2 screwdriver (supplied), remove the two Phillips screws
securing the four red brackets (two on each side) to the chassis (see FIGURE2-1).
Youmay also need to remove the brackets from the pallet. Use the Allen key
supplied to remove the two Allen screws from each bracket. The brackets arenot
attached to the red mounting plinth.
3. Install the appropriate mounting flanges.
Refer to “Mounting Flanges” on page 13.
4. Use an appropriate lifting device to lift the chassis by the red mounting plinth,
and install it in the rack.
Caution – If using a fork-lift device, ensure the tines of the lift extend right through
the mounting plinth and beyond the rear of the chassis. The chassis could deform if
you use incorrect lifting techniques.
5. Secure the chassis into the rack using the appropriate mounting points.
See “Mounting Flanges” on page 13.

Mounting the chassis with the plinth attached ensures that the minimum amount of
clearance for air flow is provided beneath the system.

the chassis revealed by the removal of the plinth.
Refer to “ToInstall the Filter Trays” on page 36. The filter tray thumbscrews are
inserted in the tapped threads exposed by removal of the mounting plinth.
