Cisco EtherSwitch 4 Port Switch HWIC-4ESW=

BRAND NEW WITH THE FULL CISCO WARRANTY!!! Cisco EtherSwitch HWICs are 10/100BaseT Layer 2 Ethernet switches with Layer 3 routing capability. (Layer 3 routing is forwarded to the host, and is not actually performed at the switch.). Traffic between different VLANs on a switch is routed through the router platform. Any one port on a Cisco EtherSwitch HWIC may be configured as a stacking port to link to another Cisco EtherSwitch HWIC or EtherSwitch network module in the same system. An optional power module can also be added to provide inline power for IP telephones.
