Cisco Catalyst 4500 Series Line Cards
Fast Ethernet and Gigabit Line Cards
The Cisco® Catalyst® 4500 Series scalable, modular, high-density switches deliver high performance and integrated Layer 2, 3, and 4 switching with intelligent services for network control and resiliency. These switches offer a variety of Fast Ethernet and Gigabit Ethernet line cards that include fiber and copper interfaces optimized for desktops, branch office backbones, and servers for enterprise and commercial switching solutions, and service provider metropolitan Ethernet networks. Gigabit Ethernet line cards include cost-effective, high-performance 1000BASE-X gigabit interface converter (GBIC) and Small Form-Factor Pluggable (SFP)-based Gigabit Ethernet line cards and the high-density 10/100/1000BASE-T triple-speed autosensing, autonegotiating Gigabit Ethernet line cards. Fast Ethernet line cards include various densities of wire-speed 10/100, 100-FX, 100BASE-LX10, and 100BASE-BX-D options.
Power over Ethernet Line Cards
The Cisco Catalyst 4500 Series offers line cards, power supplies, and accessories required to deploy and operate a standards-based Power over Ethernet (PoE) internetwork. PoE provides -48 VDC power over standard Category 5 unshielded twisted-pair (UTP) cable up to 100 meters when an IEEE 802.3af-compliant or Cisco Systems® prestandard powered device is attached to the PoE line card port. Instead of requiring wall power, attached devices such as IP phones, wireless base stations, video cameras, and other IEEE-compliant appliances can use power provided from the Cisco Catalyst 4500 Series PoE
line cards.
Ethernet in the First Mile
Cisco Catalyst 4500 Series line cards for delivering Ethernet in the First Mile (EFM) fulfill the high-density, high-bandwidth, and long-reach requirements of network operators to build next-generation metropolitan-area networks. Cisco Catalyst 4500 Series EFM line cards let service providers deliver any combination of data, voice, and video services over a single optical connection to homes, business parks, and multitenant units. EFM line cards also are appropriate for manufacturing facilities, transportation monitoring, and fiber-to-the-desktop applications. Ethernet over fiber enables operation in noisy electromagnetic environments, providing physical security and longer reaches with the same well-understood Ethernet transport. EFM line cards include 1000BASE-X, 100FX, 100BASE-LX10, and 100BASE-BX-D for fiber-based options and 10/100 or 10/100/1000BASE-T line cards for copper-based options when media converters are used.
