CAUTION: THE ANTENNA ASSEMBLY MUST BE INSTALLED BY AN AUTHORIZED, CLEARWIRE APPROVED

CONTRACTOR IN ACCORDANCE WITH STATE AND LOCAL BUILDING AND ELECTRICAL CODES.

Installation of the Outdoor Unit and Antenna for Compliance with FCC RF Exposure Requirements

The Outdoor Unit (2401-02) is mechanically and permanently secured to the antenna as one complete assembly. The

whole assembly is, at all times, required to either be installed on the roof of the building, on the side of the building,

pointing outward, or on an antenna tower. The minimum height above ground is 10 feet. In addition, to meet FCC RF

Exposure requirements, the installation must be carried out by professional technical staffs according to Clearwire

installation procedures. The antennas specified in this permissive change application may only be used in point-to-point.

Below: Figures 3-1, 3-2 and 3-3 depict typical antenna installations:

WARNING: INSTALLING ANTENNAS NEAR POWER LINES IS DANGEROUS. FOLLOW THE MANUFACTURER’S INSTRUCTIONS IN ACCORDANCE WITH THE RECOMMENDATIONS OF THE U.S. CONSUMER PRODUCT SAFETY COMMISSION. Antenna installation includes the following: 1. Safety Precautions: • Check for overhead power lines before beginning installation. Stay at least twice the length of the antenna away from all power lines.

• Ground the RF cable at the bottom of the tower. • Cadwelds underground. • Double lug compression above ground. Bolts must be stainless steel. • Kopr-Shield all mechanical interfaces. • 2-Point grounding to inside of building. • Halo ground installed at least 18 in. below grade. • Halo comprised of #2 AWG tinned solid copper wire. • Test the grounding system to prove system less than 10 ohms. • All grounds should "flow downstream" with minimum bend radius (6 in. for #6, 12 in. for #2).

CONFIGURATION: Before beginning normal operation you must perform IDU configuration and PC configuration. IDU Configuration: Local configuration of each IDU will give each Subscriber Unit sufficient information to establish a session with a Master Unit. Each IDU must be configured with the proper IDU IP address, subnet mask, transmit frequency channel, receive frequency channel, and maintenance mode setting. This can be accomplished either before installation or on site.

• At the [VxWorks Boot] prompt, enter "@" to reboot with the changed parameters. • At the Press any key to change device parameters prompt, press any key to advance to the Security Log-On. Enter the appropriate Account Name and password to advance to the Device Parameters Menu. Table 2-4 shows the Device Parameters Menu. Table 2-4. Device Parameters Menu 1. Maintenance Mode Set to DISABLED for normal operation. 2. GPS Pulse Fakeout Set to DISABLED for normal operation. 3.

IP Address of Gateway (same as ISP Direct) Before you configure each PC, verify that it has network interface card and is able to communicate with the ISP Direct®. The best way to do is to use ping utility. At the DOS prompt, type C:\> ping If there is a connection problem, you will see a request timed out message. This indicates that you don’t have the proper TCP/IP connection locally. • Check the LAN LINK LED on the IDU front panel. It should be lit, indicating an Ethernet link.

Figure 3-10. 5. DNS server configuration. The DNS server program that runs at the ISP side resolves domain names to IP addresses. To be connected to Internet, the PC has to know the IP address of this server in order to request IP resolution. Most ISP’s have a primary and a secondary DNS server. a. For Windows 95® or 98®: 1) Select the DNS Configuration tab. 2) Check the Enable DNS button. 3) Enter the DNS server IP address. 4) Click the Add button.
