This chapter contains information about the antennas for the Cisco 1240 Connected Grid Router. Router
antennas provide connectivity to the GPS satellite and provide WiFi access unit, as well as to the
Cisco Connected Grid modules installed in the router.
This chapter contains the following sections:
•
Installing or Replacing Antennas, page 10-1

Installing or Replacing Antennas
Depending on the configuration you specified, the router could arrive in the shipping container with all
required antennas already installed and connected to the corresponding Cisco Connected Grid modules,
also installed in the router.
However, you might need to install an antenna when:
•
You purchase a module separately from the router. The antenna is included with the module, and
must be installed on the router to complete the module installation.
•
You purchase an antenna separately to replace a faulty or damaged antenna.
For procedures and safety information required to install or replace antennas, see the Connected Grid
antennas documentation, at:
www.cisco.com/go/cg-modules.
Lightning Arrestor
Every external antenna that is installed on the router requires a lightning arrestor. External antennas are
any antennas that are connected to the router antenna port N-connector (
Figure 10-3
illustrates a router
N-connector) with a cable.
More information:
•
You can order lightning arrestors from Cisco using Product ID (PID): CGR-LA-N-N.
