Part # WS-X4148-RJ45V

Product Description: Cisco Catalyst 4000 Series - Inline Power 10/100BASE-TX Switching Line Card:

48 ports 10/100BASE-TX per line card (RJ-45)—Each Cisco Catalyst 4006 Series switch has up to 240 10/100 Fast Ethernet ports.

Inline power—48-VDC power is provided over standard Category 5 UTP cable up to 100 meters.

Phone discovery—The Cisco Catalyst 4000 Switch automatically detects the presence of an IP phone and supplies inline power.

Auxiliary VLAN via 802.1Q—The Cisco Catalyst 4000 Switch automatically segments phones and data endpoints into separate, logical networks.
