Fan tray handles
The fan tray installs horizontally in the rear of the chassis. The fan tray has two handles,
one on each side, that facilitate handling of the fan tray.
You remove and replace the fan tray from the rear of the chassis. The switch continues
to operate for a limited time (15 seconds) during the replacement of the fan tray without
thermal shutdown.
The fan tray provides front-to-back or back-to-front airflow depending on the switch
model you purchase. Each fan tray displays an
INTAKE
or
EXHAUST
label on the right
side and arrow icons on the tops of the handles to indicate the airflow direction. (See
Figure 14 on page 25.)

chassis and pushed toward the fan tray. Hot air exhausts from the rear of the chassis.
See Figure 15 on page 26.
NOTE:
The network ports are located on the front of the switch.
