The pads keep the switch from scratching the supporting surface and help ensure adequate airflow
around the switches when they are mounted on top of one another.
Caution
You can not stack any switches on top of a desk mounted X430-8p switch. Do not place any
equipment on top of a desktop mounted Summit X430-8p switch.
For all Summit switches other than the X430-8p, you can safely stack up to four switches on
top of one another.
Caution
If you are desktop mounting Summit X440-8t switches directly on top of each other, you
must use the four rubber pads to maintain adequate airflow around the units.
To desktop mount your summit switches:
1 Carefully separate the four included rubber pads for each switch you are mounting.
2 Apply the pads to the underside of each device by placing a pad in the marked area at each corner
of the switch, ensuring that all corners are aligned.
