Installing the Adapter Plates

Two adapter plates come with the mounting kit. Adapter plates are used to secure the chassis to:

The rail and extension assemblies used in the four-post rack configuration (see Four-Post Rack Mount Installation).
The rail and mid-bracket assemblies used in the two-post rack configuration (see Two-Post Rack Mount Installation).

The adapter plates can be installed in either a flush or a recessed configuration of up to 3.8 cm (1.5 in.).

The SSA switch can be configured for air intake on either the chassis switch I /O port side or the power supply side. Adapter plate installation must align the adapter plate ears with the air intake side of the chassis.

If you have not verified the power supply and fan module airflow for the chassis you are installing, see Power Supply Airflow and Switch Fan Module Airflow for information on determining airflow direction for your chassis before installing the adapter plates.

If the current fan module airflow direction does not match the intended chassis airflow direction, see Reversing the Fan Module Airflow.

To install the adapter plates, follow these steps:

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

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.
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 or Two-Post Rack Mount Installation.
