Connecting System Grounding

Connecting System Grounding
Before you connect power or turn on power to the Cisco 12012, we strongly recommend
that you provide an adequate system grounding (earth) connection for your system. Two
system grounding receptacles are provided on each Cisco 12012. (See Figure 3-24.)
To ensure the system grounding connection that you provide is adequate, you will need the
following parts:
•
Two grounding lugs—Must have two M6 holes that have a 0.625-inch to 0.75-inch
(15.86-mm to 19-mm) spacing between them and a wire receptacle large enough to
accept a 4-AWG, or larger, multistrand copper wire. This type of grounding lug is not
available from Cisco Systems; electrical-connector vendors, such as Panduit, provide
this type of grounding lug.
•
Four M6 or equivalent hex-head bolts with locking washers and nuts—This mounting
hardware is not available from Cisco Systems; it is available from any commercial
hardware vendor.
•
Two grounding wires—4 AWG (0.204-inch [5.18-mm] diameter) or larger. The actual
wire diameter and length are dependent on your router location and site environment.
This wire is not available from Cisco Systems; it is available from any commercial cable
vendor.
