Prerequisites 3G Wireless WAN Interface Cards REVIEW DRAFT-CISCO CONFIDENTIAL Prerequisites Before you connect, make sure you have done the following: • If you are a Cisco HWIC-3G-GSM user, before you connect the HWIC to the network, you need to install the SIM card. See the "Installing a SIM Card in the HWIC-3G-GSM" section on page 7. • Make sure you have subscribed to an appropriate GSM or CDMA service plan with your wireless service provider. • Choose an antenna that best suits your needs. See the "Connecting an Antenna with the 3G Wireless WAN HWIC" section on page 10. Warning This equipment must be connected to an indoor antenna only. Statement 373 • Although the use of two antennas is not required, both antennas can be used to take advantage of diversity antenna mode for the best RF performance. • Contact your carrier for information on network coverage, signal strength, choosing a suitable antenna, and antenna placement. Note The diagnostics port is to be used as an advanced diagnostics tool. Do not use this port for normal operations. Restrictions Limitations of the 3G wireless HWICs include the following: • Only one 3G wireless HWIC is supported in the router at a time. Multiple 3G wireless HWICs on a single chassis is not a supported configuration at this time. • The 3G wireless HWIC must be installed in an HWIC slot.
