a) Clean the indentations at each corner of the bottom of the device to ensure that they are free of
dust or other debris that might lessen the adhesion of the feet.
b) With the adhesive side against the chassis, place one rubber foot in each indentation and press into
place.
3. Place the device on a sturdy flat surface.
4. Provide power to the device as described in "Providing power to the device" on page 34.
Note: Do not connect the device to the network until the IP address is set correctly. For instructions on
how to set the IP address, refer to "Configuring the IP address" on page 35.
Installing the Universal Four-Post Rack Kit
Use the following instructions to install 1U and 2U devices in EIA racks that are between L-12.7 to 81.28
cm deep (L-5.0 to 32.0 in.), where L is the chassis depth, using the Universal Four-Post Rack Kit.
There are two ways you can mount the device in a four-post rack:
• With the port side flush with the front posts.
• With the nonport side flush with the rear posts in a recessed position. A recessed position allows a more
gradual bend in the fiber-optic cables connected to the switch and less interference in the aisle at the
front of the rack.

Note that if chassis depth (L) is less than 40.64 cm (16 in.), the chassis will not fit into a rack with a
maximum depth of 81.28 cm (32 in.) using the universal four-post rack kit. The maximum rack depth for
a chassis less than 40.64 cm (16 in.) is 81.28 cm (32 in.) minus the difference between the chassis depth
and 40.64 cm (16 in.). For example, a chassis with a depth (L) of 35.56 cm (14 in.) is 5.08 cm (2 in.)
smaller than 40.64 cm (16 in.), so it will install into a rack with a maximum depth of 81.28 cm (32 in.) -
5.08 cm (2 in.) = 76.2 cm (30 in.).
Observe the following when mounting this device:
• Two people are required to install the device in a rack. One person holds the device, while the other
