3.6.3 Grounding the Switch
Check to determine if your local or national electrical codes require an external ground to all IT
components. If so, connect a ground wire to one of the casing screws and connect the other end to
a valid ground. If you choose to not use the ground screw, make sure that the rack is properly
grounded and that there is a valid ground connection between the chassis of the switch and the
rack. Test the ground using an Ohm meter.
Warning: Any yellow status LEDs is cause for concern and must be dealt with imme-
diately.
It can take up to 5 minutes to boot up, during which time the status LED may indicate
red.
Some national and/or local codes may require IT components to be bonded and exter-
nally grounded (not including the power cord ground). You must follow all national
and local codes when installing this equipment.
