Grounding the JSA7500 Appliance
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must adequately ground the JSA7500 appliance before connecting
it to the power source.
You can ground the JSA7500 appliance either from the side of the chassis or from the
rear panel. If you use the grounding lug, then we recommend that you use the grounding
points available on the side of the chassis.
Table 28 on page 97 lists the specifications of the grounding cable and grounding lug
used with the JSA7500 appliance.
