NOTE: Grounding is required for DC systems and recommended for AC
systems. An AC-powered switch gets additional grounding when you plug
the power supply installed in the switch into a grounded AC power outlet
using the appropriate power cord.
CAUTION: For installations that require a separate grounding conductor to
the chassis, use the protective earthing terminal on the switch chassis to
connect to earth ground. Before switch installation begins, a licensed
electrician must attach a cable lug to the grounding cables that you supply.
See "Connecting Earth Ground to an EX Series Switch" on page
with an incorrectly attached lug can damage the switch.
A pair of threaded inserts (PEM nuts) is provided on the rear towards the bottom of the
EX6210 chassis for connecting the switch to earth ground. The grounding points fit UNC
¼-20 screws. The grounding points are spaced at 0.625 in. (15.86 mm). See
Figure 30 on page 84 for the location of the protective earthing terminal.
