Using the Business Policy Switch 2000 Version 2.0
Cooling fans
Three cooling fans are located on one side of the Business Policy Switch to
provide cooling for the internal components. (See
Figure 1 on page 40 .) When
you install the switch, be sure to allow enough space on both sides of the switch
for adequate air flow. See Installing the Business Policy Switch 2000 for detailed
information.
AC power receptacle
The AC power receptacle accepts the AC power cord (supplied). For installation
outside of North America, make sure that you have the proper power cord for your
region. Any cord used must have a CEE-22 standard V female connector on one
end and must meet the IEC 320-030 specifications.
