The 4- and 9-port Cisco EtherSwitch HWICs (part numbers HWIC-4ESW and HWIC-D-9ESW) are managed 10/100BASE-T Layer 2 switches in a HWIC form factor for the Cisco Integrated Services Routers. The 4-port HWIC comes in a single-wide form factor, and the 9-port HWIC in a double-wide form factor. The switch supports the IEEE 802.1D Spanning Tree Protocol and can be used to connect up to 4 or 9 LANs with up to 15 IEEE 802.1Q-based VLANs (802.1Q). Note: Both HWICs-the 4- and 9-port HWICs-support up to 15 VLANs. They also can be optionally configured to provide 4 or 8 ports of inline power for 802.3af- or Cisco PoE-capable devices. The PoE support is not available on the Cisco 1841 router.
