Summit 400-48t Switch Overview and Installation
Installing the Switch
The Summit 400-48t can be mounted in a rack, or placed free-standing on a tabletop.
Rack Mounting
CAUTION
Do not use the rack mount kits to suspend the switch from under a table or desk, or to attach the switch
to a wall.
To rack mount the Summit 400-48t:
1 Place the switch upright on a hard flat surface, with the front facing you.
2 Remove the existing screws from the sides of the case (retain the screws for Step 4).
3 Locate a mounting bracket over the mounting holes on one side of the unit.
4 Insert the screws and fully tighten with a suitable screwdriver, as shown in Figure 5.

5 Repeat steps 2 through 4 for the other side of the switch.
6 Leave a half-rack space between the units for adequate ventilation. This space is especially important
for Summit 400-48t switches that have the optional ER XENPAK transceiver installed.
7 Insert the switch into the 19-inch rack.
8 Secure the switch with suitable screws (not provided).
9 Connect the switch to the redundant power supply (if applicable). For further details of installing
this option, see “Installing the External Power System” on page 42.
10 Connect cables.
Free-Standing
The Summit 400-48t is supplied with four self-adhesive rubber pads. Apply the pads to the underside of
the device by sticking a pad in the marked area at each corner of the switch.
