The WS-X4248-RJ45V is a Cisco Catalyst 4500 PoE line card with 48 ports of 10/100 Ethernet on RJ-45 connectors. It belongs to the classic 10/100 Ethernet line cards for the Catalyst 4500 Series and supports IEEE 802.3af Power over Ethernet and Cisco prestandard PoE.
The card needs Cisco IOS Software Release 12.2(18)EW or later. Its PoE powers IP phones, wireless base stations, video cameras and other IEEE-compliant powered devices, with 10/100 connectivity on every port. The ports run at wire rate.
In a Catalyst 4503-E the port count runs from 48 to 96 with this card type, in a 4506-E, 4507R-E or 4507R+E from 48 to 240, and in a 4510R-E or 4510R+E from 48 to 384. A Supervisor Engine 8-E or 7-E is needed to go beyond 240 ports on a 4510R+E.
A 48-port 10/100 card without PoE is the WS-X4148-RJ, and a Fast Ethernet fiber card is the WS-X4248-FE-SFP with 48 SFP ports. For a gigabit PoE card, see the WS-X4548-GB-RJ45V Catalyst 4500 48-port PoE module. More line cards are in Cisco switches.
