Chapter 1 Product Overview

Cisco 810 Series

Antennas

The Cisco 819 3G routers provide two standard panel-mount TNC connectors to support the 3G antenna and the diversity and GPS external antenna. The main antenna is used for the primary 3G antenna. The second can be used as a diversity receive only 3G antenna or GPS antenna that does not require power supply from the router.

The Cisco 819 4G routers provide two standard panel-mount TNC connectors on the router front panel for the main and diversity antennas. The main antenna connector is used for the primary 4G antenna. The second antenna connector can be used as a diversity receive only 4G antenna. An SMA connector for active GPS antenna is also available on the front panel of the router.

The Cisco 819HGW and Cisco 819HWD ISRs also support Cisco WiFi external antennas. See the “Supported Cisco Antennas and Cables” section on page 1-27for more information.

WiFi External Antenna

The external WiFi antenna is used to support better WiFi coverage. All external antenna supports the following:

•Dual 802.11 a/b/g/n radios

•2x3 MIMO

•Omnidirectional

Power Switch

The power switch shuts down the router. A power switch lock is available to prevent accidental turning off of the router in the hardened SKUs.

Reset Button

The Reset button resets the router configuration to the default configuration set by the factory. To restore the router configuration to the default configuration set by the factory, use a standard size #1 paper clip with wire gauge 0.033 inch or smaller and simultaneously press the reset button while applying power to the router.

LEDs

The LEDs are located on the front panel of the router. Table 1-8describes the 3G LEDs for the Cisco 819 ISR.
