Connecting Earth Ground to an EX Series Switch | 170
To ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements, you
must connect an EX Series switch to earth ground before you connect power to the switch. You must use
the protective earthing terminal on the switch chassis to connect the switch to earth ground (see
Figure 49 on page 171).
You must install the EX Series switch in a restricted–access location and ensure that the chassis is always
properly grounded. EX Series switches have a two–hole protective grounding terminal provided on the
chassis. See Table 68 on page 165
We recommend that you use the protective grounding terminal as the preferred method for grounding
the chassis regardless of the power supply configuration. However, if additional grounding methods are
available, you can also use those methods. For example, you can use the grounding wire in the power cord
for the location of the earthing terminals on various EX Series switches.
