Installing the Cisco 810 ISR

Installing Antennas

Note Before you install the Cisco 819 ISR on a table, wall, or DIN rail, install the antennas on the front panel. It is difficult to install the antennas after the router is installed.

To attach the radio antennas to your wireless router, follow these steps:

Step 1 Manually screw the antenna tight to the TNC connectors on the back of the router. (See Figure 2-19.)

Step 2 Orient the antennas. For optimum wireless performance, antennas should be generally perpendicular to each other.

If the router is being mounted on a desk, orient the antennas straight up.

Installing a WiFi External Antenna

This section describes how to install a WiFi external antenna.

Step 1 Install the lightning arrestor. For details in installing lightning arrestor, see Cisco Aironet Lightning Arrestor (AIR-ACC245LA-R).

Step 2 Rotate the knurled portion of the WiFi external antenna clockwise to screw the antenna to the RP-TNC. (See Figure 2-20.)

Note WiFi antennas should be generally perpendicular to each other to achieve best coverage.
