Step 4
Connect the other end of the ground wire to a known good electrical ground point. Consult with a
licensed electrician if you have any questions about the suitability of the ground connection.
After the router is installed and properly grounded, you can connect the WAN and LAN cables as
required for your installation. For cable connection procedures, see

Installing the Chassis Ground Connection on the Cisco 1861 Integrated Services
Router
You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance
with local electrical safety standards.
For NEC-compliant grounding, use size 14 AWG (2 mm) or larger copper wire and an appropriate
user-supplied ring terminal with an inner diameter of 1/4 in. (5 to 7 mm).
Note
The Cisco 1861 Integrated Services Router is not NEBS-compliant.
Warning
This equipment needs to be grounded. Use a green and yellow 14 AWG ground wire to connect the
host to earth ground during normal use.
Statement 190
To connect the chassis to a reliable earth ground, perform the following steps:
Step 1
Strip one end of the ground wire to the length required for the ground lug or terminal.
•
For the ground lug, approximately 0.75 in. (20 mm)
•
For the user-provided ring terminal, as required
Step 2
Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 3
Attach the ground lug or ring terminal to the chassis as shown in
Figure 4-12
