2 Align either the flush mount adapter plate screw holes (Callout 2) or the appropriate recess mount
adapter plate screw holes with the three chassis screw holes on each side of the chassis.
Callout 3 identifies the screw holes used to recess the chassis by .5, 1.0, or 1.5 inches.
Note
When recess mounting, use care that the installation does not result in openings above
and below the chassis face at the inlet side that allow for hot air recirculation from the
exhaust side of the rack or cabinet. This is especially the case for a cabinet with enclosed
sides where the cold and hot aisles are meant to be isolated.
3 Insert and tighten three of the six 6-32 flat head screws that come with the mounting kit in three
places on each side of the chassis.
You are ready to install the rails and put the chassis into the rack. Proceed to the appropriate topic:
Four-Post Rack Mount Installation on page 56 or Two-Post Rack Mount Installation on page 59.
Four-Post Rack Mount Installation
The rack mount option kit supports the flush mount configuration for a four-post rack installation, with
the option of recessing the chassis a maximum of 3.8 cm (1.5 in.). Both airflow directions are supported.
Figure 24 displays the four-post rack flush mount configuration for both airflow directions. The recessed
chassis configurations (configured when installing the adapter plates, see Figure 23 on page 55) are not
displayed.
