SKU CH-DBRK-TPFDY

Four-port 10/100 Ethernet switch module for Cisco 1800, 2800 and 3800 routers

  • Adds four Ethernet ports to 1800, 2800 or 3800 routers
  • 10/100 switch ports connect wired devices directly
  • WAN interface card fits fixed-configuration router slots
  • New condition ensures reliable first-time installation

WAN Interface Card for Cisco Routers

The HWIC-4ESW adds a four-port 10/100 Ethernet switch to compatible 1800, 2800 and 3800 series fixed-configuration routers. It is intended for network administrators who need to expand LAN connectivity directly inside the router chassis without deploying a separate switch.

Passive Operation in Router Slot

The card draws power from the router backplane and has no onboard fans, so it adds no audible noise and minimal thermal load to the system. Power consumption is limited to the slot budget of the host router, leaving the existing cooling arrangement unchanged. Buyers who require Gigabit speeds or Power over Ethernet will need a different interface card.

Questions about this item

How is the HWIC-4ESW installed in a 1800 2800 3800 router, and what step is often missed?

Power off the router, slide the card into an available HWIC slot until the connectors seat firmly, then tighten both captive screws; the step often missed is securing both screws, which ensures proper electrical contact and prevents the card from working loose.

What maintenance or replacement will the HWIC-4ESW 4-port 10/100 Ethernet switch card need later?

The card itself has no moving parts or consumables; maintenance is limited to keeping the router's airflow clear so the 10/100 ports stay cool, and replacement is only needed if a port fails or the router is upgraded beyond the 1800 2800 3800 platform.
