A financial services firm equips each remote branch with a Cisco 2900 router hosting the EHWIC-D-8ESG-P. The eight-port PoE switch card powers VoIP phones and wireless APs while enforcing per-VLAN firewall and QoS policies. Benefit: Consolidated routing, switching and security in a single chassis reduces hardware footprint by 50%, speeds deployment by 40%, and ensures end-to-end network segmentation for regulatory compliance.
A nationwide retailer deploys Cisco 1900 routers with EHWIC-D-8ESG-P cards in every store to isolate POS terminals, digital signage and PoE cameras on distinct VLANs. Built-in QoS prioritizes transaction traffic over surveillance feeds, and centralized IOS management provides real-time health monitoring. Outcome: 99.9% transaction uptime, 30% reduction in onsite troubleshooting, and seamless PCI-DSS compliance through segmented, auditable network zones.
A manufacturing plant integrates a Cisco 3900 router equipped with the EHWIC-D-8ESG-P to aggregate PoE-powered sensors, actuators and HMIs across the factory floor. VLAN tagging and low-latency switching ensure deterministic OPC-UA and SCADA communications, while the router’s WAN uplinks deliver secure cloud connectivity. Outcome: 15% boost in production efficiency, simplified edge device provisioning, and unified WAN/LAN management for real-time diagnostics.

The EHWIC-D-8ESG-P is a reliable Ethernet switch card. It integrates easily with our Cisco routers and provides stable connectivity.
Great performance and flexibility. The EHWIC-D-8ESG-P is perfect for handling multiple Ethernet interfaces and is easy to manage.
We use the EHWIC-D-8ESG-P in our Cisco routers for high-speed Ethernet connections. It has been a reliable addition to our network.
The EHWIC-D-8ESG-P provides solid performance and easy scalability. It's perfect for high-bandwidth environments where reliability is key.
This card integrates seamlessly into our infrastructure. The EHWIC-D-8ESG-P offers reliable Ethernet connectivity for our enterprise-grade routers.
The Cisco EHWIC-D-8ESG-P is an Enhanced High-Speed WAN Interface Card that delivers an integrated eight-port Gigabit Ethernet switch for ISR 1900, 2900 and 3900 series routers.
The EHWIC-D-8ESG-P is compatible with Cisco ISR 1900, 2900 and 3900 series routers, providing built-in switching for branch and enterprise deployments.
The module offers eight autosensing 10/100/1000 Mbps Gigabit Ethernet ports with wire-speed switching and auto-MDI/MDIX on each interface.
No. The EHWIC-D-8ESG-P does not include PoE or PoE+ capabilities; it provides only data switching without power delivery to connected endpoints.
The module supports VLAN tagging, QoS, MAC address learning, Spanning Tree Protocol, port security and advanced Layer 2 switching at wire-speed.
Power off the router, insert the EHWIC-D-8ESG-P into any EHWIC slot, secure with the retention screw, and power on. Confirm installation via the CLI "show hw-module" command.
No. The EHWIC-D-8ESG-P is not supported for hot swapping; you must power down the router before installation or removal.
The EHWIC-D-8ESG-P delivers up to 16 Gbps of total switching capacity and wire-speed performance across all eight ports.
The module operates under Cisco IOS with LAN Lite or LAN Base feature sets. Advanced features require appropriate Cisco IOS feature licensing.
Yes. You can configure 802.1Q VLAN trunking and access ports on each of the eight Gigabit Ethernet interfaces for network segmentation.
No separate hardware license is required. You only need the correct Cisco IOS software license (LAN Base or IP Services) for advanced features.
The module draws less than 10 W from the router’s internal power supply. Ensure the router PSU meets the overall power budget for all modules.
Unlike legacy HWICs, the EHWIC-D-8ESG-P offers Gigabit Ethernet, higher switching capacity, and support for ISR G2 and 3900 platforms for enhanced performance.
Cisco provides a limited lifetime warranty on the EHWIC-D-8ESG-P with return-to-factory repair or replacement. Extended support requires a Cisco SMARTnet contract.
You can buy the Cisco EHWIC-D-8ESG-P from authorized Cisco resellers, the Cisco online store or partners listed on Cisco’s official website.
Use the Cisco IOS command "show platform hardware slot <slot> status" or "show interface status" to confirm link, speed and module health.
The module measures 6.2 x 4.0 x 0.6 inches (157 x 102 x 15 mm) and weighs approximately 0.3 lbs (0.14 kg), fitting standard EHWIC slots.
