Place the switch on a flat surface
The switch ships with four self-adhesive rubber footpads.
To install the switch on a flat surface:
Stick one rubber footpad on each of the four concave spaces on the bottom of the
switch.
The rubber footpads cushion the switch against shock and vibrations. They also
provide ventilation space between stacked switches.
Optional Step 5: Install SFP or SFP+
transceiver modules
This procedure is optional. The following table shows the models and the ports that
