Installing the Air Filters
a) On the back side (open side) of one door, pull in on two protruding spring pins so that the pins are held
inside the door frame (see the following figure). Hold these two pins in through the next step.
Figure 22: Installing a Front Door Over the Supervisor and I/O Module Area
b) Position the door with the back (open) side facing the front of the chassis and the two held spring pins
aligned to two holes in the top hood and divider bracket as shown in the previous figure.
c) Release the two spring pins so that they insert into the holes in the top hood and divider brackets.
The door should freely swing on the spring pins.
d) Close the door to cover half of the supervisor and I/O module area.
Magnets in the door will hold the door shut to the door-stop bracket on the top hood and to the divider
bracket.
e) Repeat Steps 4a through 4d to install the other front door.
Step 5
Install the door in front of the power supply area as follows:
a) Position the door to the power supply area so that its two bars on the backside are resting on two holders
protruding from the left and right power supply cable management frames as shown in the following figure.
Figure 23: Positioning the Power Supply Door on the Chassis
b) Rotate the top of the door to the divider bracket installed on the cable management frames.
The magnets on the door hold the door to the divider bracket.
Installing the Air Filters
You can optionally install six air filters on the two front doors and the left and right cable management frames.
These air filters significantly reduce the air particulates that can enter into the air intakes for the supervisor
and I/O modules.
