Installing the Adapter Plates

1. Place the adapter plates on each side of the chassis with the ear end toward the air intake side of the chassis, ear flange pointing away from the chassis.
   Installing the Adapter Plates shows the correct orientation for a chassis with airflow from switch I/O port side to power supply side.

   

   Installing the Adapter Plates

   

   1 = Adapter plate (ear side)	3 = Recess mount adapter plate screw holes (1.5 in.)
   2 = Flush mount adapter plate screw hole	4 = Airflow direction

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.
