Installing the Switch Chassis
• Verify that you have the following tools or equipment:
Step 1
Attach the divider bracket to the left and right cable management side assemblies as follows:
a) Position the divider bracket between the right and left cable management assemblies between the bottom I/O module
and the power supplies. The back edge of the divider bracket has two curved corners that should come in contact
with the chassis.
b) Align the two slots on both sides of the bracket with the pins that stick out from the upper portion of the lower cable
management frame (power-supply cable management frame) and lower the bracket past the pins until the bracket
stops.
c) Push the bracket about 0.5 inches (1 cm) to the front of the chassis until it stops.
A screw hole on each side of the divider bracket aligns with a screw hole in each cable management side assembly.
d) Secure the divider bracket to both cable management side assemblies using two M3 x 8 mm screws (one screw for
each of two sides) and tightening the screws to 5 to 7 in-lb (0.56 to 0.79 N.m) of torque.
Step 2
Insert the door filter inside the back side of the door as follows:
a) Open the front door and pull it off of the chassis.
b) Place the front of the door on a table top so that the back (open) side is facing up.
c) Remove the largest air filter from its packaging, hold the side with the hexagonal shaped holes facing up, and insert
the filter into the open back side of the door.
If necessary, push in the spring clips on the side of the filter to push the filter into the door. The filter snaps into place
on the door.
Step 3
Attach the two narrow brush filters to the sides of the door as follows:
a) Remove a long slender door-side filter from its packaging and align its two holes with two pins in the door.
b) Slide the filter down the door until it stops on the pins. Screw in the two captive screws on the filter to the door and
tighten to 8 in-lb (0.9 N·m).
c) Repeat Steps 2a and 2b to attach the other door-side filter to the door.
Step 4
Attach the two air filters to the cable management frames as follows:
a) Remove a cable management air filter from its packaging and position it on the upper portion of one of the two cable
management side frames so that its six holes align with six screw holes in the cable management frame.
b) Fasten the air filter to the cable-management assembly with the two M4 x 12 mm screws on top and four M3 x 12
mm screws below. Tighten the M4 screws to 11.5 to 15 in-lbs (1.3 to 1.7 N·m) of torque, and tighten the M3 screws
to 5 to 7 in-lb (0.56 to 0.79 N.m) of torque.
c) Repeat Steps 3a and 3b to attach the other air filter to the cable management assembly on the other side of the chassis.
