WS-X4548-RJ45V+ is a Catalyst 4500 classic line card with 48 ports of 10/100/1000 Mbps over RJ-45, and the spare form is WS-X4548-RJ45V+(=). The ports provide Power over Ethernet to IEEE 802.3af, IEEE 802.3at and Cisco prestandard devices, at up to 30 W per port on up to 24 ports at the same time.
As a classic card it receives 6 Gbps per slot. The ports are divided into six sets of 8 ports at 1 Gbps per set, which makes the card 8-to-1 oversubscribed, and the ratio can be adjusted by changing how many ports run at 1000 Mbps. IEEE 802.3x flow control is supported, and with an E-Series supervisor each port has eight queues, since the line card inherits the supervisor engine features.
The card fits the Catalyst 4503, 4506, 4507R and 4510R chassis, including their -E and +E variants, and it needs Cisco IOS Software Release 12.2(50)SG or later. Maximum rated power is 60 W, a planning figure, with typical draw about 20 percent lower. Rated MTBF is 239,436 hours.
The card occupies one chassis slot and, like the other classic line cards, measures 1.2 x 14.25 x 10.75 in (3.0 x 36.2 x 27.3 cm).
