Step 5 Install the power switch lock, see the “Installing the Power Switch Lock” section on page 2-15. Tighten
the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m). Torque the hex standoff to the same torque.
Step 6 Connect the other end of the ground wire to a known reliable earth ground point at your site.
Step 7 If you are using this router in a vehicle, attach the ring terminal to the chassis using one of the screws
provided and the green or green and yellow striped wire. Connect the other end of the wire to the vehicle
ground.
After you install and properly ground the router, you can connect the power wiring, the LAN cables, and
the cables for administrative access as required for your installation.
Installing the Power Cord Retention Lock
The Cisco 819 ISRs have a power cord retention mechanism as an accessory. It locks the power cord to
the router so when a user accidentally pulls out the power cord, the power cord will not come out from
the router. For the complete list of Cisco 819 ISRs that support power cord retention lock, see Table 1-4.
This section describes how to install the power cord retention lock.
Step 1 Pre-assemble the o-ring onto the barrel of the power cord as shown in Figure 2-10.
