such as on a tabletop.
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take
special precautions to ensure that the system remains stable. The following guidelines are provided
to ensure your safety:
•
The unit should be mounted at the bottom of the rack if it is the only unit in the rack.
•
When mounting the unit in a partially filled rack, load the rack from the bottom to the top with
the heaviest component in the bottom of the rack.
•
If the rack has stabilizing devices, install the stabilizers before mounting or servicing the unit in
the rack.
Rack Mounting the Catalyst 3920
Only fixed brackets are supplied with these units. If you want to install a sliding pull-out mount, you
will need to provide the extra mounting hardware. Follow these steps to mount the Catalyst 3920 in
a rack:
Step 1
Look at the rack inventory chart provided by your network administrator to determine
where in the rack the Catalyst 3920 should be mounted.
Step 2
Obtain the L-shaped mounting brackets and four 8-mm M5 screws that are supplied with
the unit in the accessory kit.
Step 3
Using a Phillips (cross-head) screwdriver, attach an L-shaped mounting bracket to each
side of the Catalyst 3920 with two 8-mm M5 screws (see Figure 3-1).
