The Cisco EHWIC-3G-EVDO-S is a high-speed, 3G EV-DO WAN interface card designed for Cisco 3900 Series routers, delivering reliable cellular connectivity where wired DSL or T1 are unavailable.
The EHWIC-3G-EVDO-S is compatible with Cisco 3900 Series Integrated Services Routers (ISR), including the 3925, 3945, and 3945E models.
The card supports CDMA2000 1xEV-DO Rev. A networks, ensuring uplink speeds up to 1.8 Mbps and downlink speeds up to 3.1 Mbps.
Power down the router, insert the EHWIC-3G-EVDO-S into an available EHWIC slot, secure the retaining screw, replace any covers, and power the router back on.
Use the router CLI: enter interface cellular 0/0/0, set dialer pool 1, configure dialer string and APN, then apply ‘ip address negotiated’ and ‘no shutdown’ commands.
The EHWIC-3G-EVDO-S uses a standard RUIM (Removable User Identity Module) card from your CDMA carrier; no SIM adapter is needed.
Yes, you can configure the EHWIC-3G-EVDO-S as a secondary WAN link using Cisco IOS IP SLA and object tracking for automatic failover.
The card draws a maximum of 5 W from the router’s backplane and operates within the standard Cisco EHWIC power budget.
It is compatible with major CDMA carriers in North America, including Verizon, Sprint, and regional operators supporting EV-DO Rev. A.
No, the EHWIC-3G-EVDO-S supports data-only EV-DO services and does not provide voice or SMS functionality.
Use ‘show cellular 0/0/0 all’ in the CLI to view signal strength, registration state, APN, and data session statistics.
The card operates between 0°C and 40°C with up to 90% relative humidity non-condensing, per Cisco environmental specifications.
Yes, the card supports Cisco IOS security features such as VPN, IPsec, and firewall filtering to protect cellular traffic.
Upload the latest Cisco IOS image supporting the EHWIC-3G-EVDO-S, then reload the router; the firmware on the module updates automatically.
