The Cisco EHWIC-4ESG is a four port 10/100/1000 Base-TX Gigabit Ethernet switch interface card designed to add integrated switching to Cisco 1900, 2900, and 3900 series routers.
The EHWIC-4ESG is compatible with Cisco Integrated Services Routers in the 1900, 2900, and 3900 series, including models like ISR 1921, 2921, 3945, and similar.
Key features include four Gigabit Base-TX switch ports, wire-speed forwarding, VLAN trunking, QoS support, and centralized management via Cisco IOS.
To install, power down the router, remove a blank EHWIC slot cover, insert the EHWIC-4ESG until latched, secure the captive screw, and power on the router.
The EHWIC-4ESG delivers wire-speed switching at up to 4 Gbps aggregate throughput across its four Gigabit ports.
Yes, each of the four ports on the EHWIC-4ESG supports auto-negotiation for speed (10/100/1000 Mbps) and duplex mode.
The EHWIC-4ESG draws approximately 3.4 watts from the router’s integrated power supply and requires no external power source.
Yes, the EHWIC-4ESG supports IEEE 802.1Q VLAN tagging, enabling up to 4096 VLANs and flexible trunk or access port configurations.
Yes, the EHWIC-4ESG supports Cisco IOS QoS features such as priority queuing, traffic shaping, and policing for each port.
The EHWIC-4ESG supports up to 8,000 MAC address entries in its hardware table for efficient layer-2 switching.
Cisco offers a limited lifetime hardware warranty on the EHWIC-4ESG with return-to-factory replacement for manufacturing defects.
No, the EHWIC-4ESG is not hot-swappable. You must power down the router before installing or removing the module.
Use Cisco IOS commands like 'show interfaces status' and check port LEDs for link/activity; verify cable integrity and speed/duplex settings.
