Airflow
The airflow through the encoder is critical for maintaining the proper temperature range. Fans
in the chassis draw air in through the front bezel and through the encoder. The airflow
ventilates out the right side (front view).
CAUTION: Do not obstruct the airflow of the encoder. Severe equipment damage can result when
the encoder cannot properly exhaust the airflow.
Attaching the Rack Rails
Attach the side-mount rack rails to the rack to hold the encoder in place.
Figure 2–1
illustrates
the parts of the rack rails.
Figure 2–1: Rack Rails
To attach the rack rails to the rack:
1. If needed, place a Tinnerman™ speed nut with the nut on the outside of the rack over the
holes to which you would like to mount the rails.
NOTE:
Each of the four rack posts requires two speed nuts.
2. Position the rack rails so the shelves are toward the inside of the rack.
3. Using the #10 screws provided with the encoder, screw the mounts into the speed nuts
from the inside of the rack using the rack-mount holes that line up with the holes on the
rack posts.
