Avoid UPS types that use ferroresonant technology. These UPS types can become
unstable with the switch, which can have substantial current draw fluctuations because
of fluctuating data traffic patterns.
Caution
•
Ensure that circuits are sized according to local and national codes. Typically, this often requires one or
both of the following:
◦
AC power supplies typically require at least a 15-A or 20-A AC circuit, 100 to 240 VAC, and a
frequency of 50 to 60 Hz.
To prevent loss of input power, ensure the total maximum loads on the circuits supplying
power to the switch are within the current ratings for the wiring and breakers.
Caution
Unpacking and Inspecting the Switch
Before you install the switch, be sure to unpack and inspect the switch for damage or missing components.
If anything is missing or damaged, contact your customer service representative immediately.
Keep the shipping container in case the chassis requires shipping at a later time.

a grounded rack or grounded chassis (there must be a metal-to-metal connection to the earth ground).
