Cisco Systems OL-27407-01 manual Grounding the Cisco 812 ISR

Chapter 2 Installing the Router

Installing the Cisco 810 ISR

Step 4 Route the cables through the bracket before you attach the bracket to the ceiling.

Step 5 Route the cables through the main cable access hole and then through the smaller access hole as shown in Figure 2-16.

Step 6 (Optional) Use the ground screw to attach the building ground wire to the ground location on the base of the router. See the “Grounding the Cisco 812 ISR” section on page 2-18for the general grounding instructions.

Step 7 Connect the Ethernet and power cables to the router.

Step 8 Align the router feet over the keyhole mounting slots on the optional mounting bracket. Step 9 Slide the router onto the optional mounting bracket until it clicks into place.

Grounding the Cisco 812 ISR

Grounding is not always required for indoor installations because the Cisco 812 ISR is classified as a low-voltage device and does not contain internal power supplies. However, it is recommended that you check your local and national electrical codes to see if grounding is a requirement. If grounding is required in your area or you wish to ground your router, perform the following steps:

Warning Use copper conductors only. Statement 1025

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Warning This equipment needs to be grounded. Use a green and yellow 12 to 14 AWG ground wire to connect the host to earth ground during normal use. Statement 242

Step 1 Find a suitable building grounding point as close to the router as possible.

Step 2 Connect a user-supplied ground wire to the building grounding point. The wire should be a minimum of #14AWG assuming a circuit length of 25 feet (30.5 cm). Consult your local electrical codes for additional information.

Step 3 Route the ground wire to the router.

Step 4 Attach the wire to a suitable grounding ring lug.

Step 5 Crimp or solder the wire to the lug.

Step 6 Use a Phillips screwdriver to remove the existing 6-32 screw at the grounding location as shown in Figure 2-17.
