Placing Units On Top of Each Other
If the switch units are free-standing, up to six units can be placed one on top of the other. If you are mixing
a variety of Baseline and Super Stack units, the smaller units must be positioned at the top.
If you are placing switch units one on top of the other, you must use the self-adhesive rubber pads supplied.
Apply the pads to the underside of each switch, sticking one in the marked area at each corner.
Place the switch units on top of each other, ensuring that the pads of the upper unit line up with the recesses
of the lower unit.

Supplying Power to the Switch

Power problems can be the cause of serious failures and downtime in your network. Ensure that the power
input to your system is clean and free from sags and surges to avoid unforeseen network outages. HP
recommends that you install power conditioning, especially in areas prone to blackout, power dips and
electrical storms.
The unit is intended to be grounded. Ensure it is connected to earth ground during normal use. Installing
proper grounding helps to avoid damage from lightning and power surges.
CAUTION:
Before powering on the switch, verify that the network cables and the power cable are securely connected.
To power on the switch:
Plug the power cord into the power socket on the rear panel of the switch.
