Cisco Catalyst 4500 E-Series and Classic Line Cards
The Cisco Catalyst 4500 Series offers two classes of line cards: classic and E-Series. Classic line cards provide 6 gigabits of switching capacity per slot. E-Series line cards increase the per slot switching capacity to 24 gigabits. This increase in per slot switching capacity with the E-Series line cards requires the Cisco Catalyst 4500 E-Series chassis and the Cisco Catalyst 4500 Series Supervisor Engine 6-E. Classic line cards may be deployed in both classic and E-Series chassis with either classic Cisco Catalyst 4500 Series supervisor engines or with the Supervisor Engine 6-E. With the Supervisor Engine 6-E, the classic line cards per slot switching capacity remains at 6 gigabits per slot. However, because of the centralized switching architecture of the Cisco Catalyst 4500, the classic line cards will adopt all of the new Supervisor Engine 6-E features such as eight queues per port,1 dynamic QoS, and hardware-based IPv6 routing. Please refer to the Supervisor Engine 6-E data sheet for more feature details. Classic line cards and E-Series line cards may be mixed and matched within a Cisco Catalyst 4500 E-Series chassis with no performance degradation: classic line cards will operate at 6 gigabits per slot, and E-Series line cards will operate at 24 gigabits per slot. Table 1 summarizes the chassis and supervisor support for both classic and E-Series line cards.

Cisco Catalyst 4500 E-Series Gigabit Ethernet Line Cards
The Cisco Catalyst 4500 E-Series 48-port Gigabit Ethernet line cards provide high-performance 10/100/1000 switching at 24 Gbps per slot. (2:1 oversubscribed). The Cisco Catalyst 4500 48-port 10/100/1000 E-Series line cards are designed for LAN access aplications where desktop users require gigabit connection speeds. The Cisco Catalyst 4500 48-port 10/100/1000 E-Series line cards are available in two versions: one with standard PoE 802.3af, and the second one with premium PoE features such as future support for 30 Watts per port.
The PoE implementation of Catalyst 4500 E-Series PoE line card (WS-X4648-RJ45V-E) is identical to the Catalyst 4500 "Classic" PoE line card (WS-X4548-GB-RJ45V) implementation. The Catalyst 4500 E-Series "Premium" PoE line card (WS-X4648-RJ45V+E) has all of the PoE features of the "Classic" and E-Series PoE card with the addition of future software upgradeability to support up to 30 Watts per port.
Cisco Catalyst 4500 E-Series 10 Gigabit Ethernet Line Card
The Cisco Catalyst 4500 E-Series now supports 10 Gigabit Ethernet line cards. The Cisco Catalyst 4500 6-port E-Series 10 Gigabit Ethernet line card (2.5:1 oversubscribed) can be deployed for high-performance 10 Gigabit Ethernet aggregation in the campus, in small to medium networks as a core switch, or for high-performance wiring closets where additional 10 Gigabit Ethernet uplinks are required. The Cisco Catalyst 4500 E-Series 6-port 10 Gigabit Ethernet line card supports standard X2 optics as well as the Cisco TwinGig modules.
The Cisco TwinGig Converter Module converts a single 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet port slots, which can be populated with appropriate Small Form-Factor Pluggable (SFP) optics, providing a total of 12 wire-speed Gigabit Ethernet ports if used in all 6 X2 interface slots. The flexibility provided by the TwinGig Converter Module enables customers to aggregate Gigabit Ethernet and 10 Gigabit Ethernet LAN access switches on a single line card. The ability to support either Gigabit Ethernet uplinks or 10 Gigabit Ethernet ports on a single line card further demonstrates the flexibility and the investment protection of the Cisco Catalyst 4500 Series architecture (Figure 1).
TwinGig modules convert a single X2 port into two Gigabit Ethernet SFP ports.

Cisco Catalyst 4500 E-Series and Classic 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 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 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. This capability gives network administrators centralized control over power and eliminates the need to install outlets in ceilings and other out-of-the-way places where a powered device can be installed.
Although all references to "PoE," "inline power," and "voice" power supplies and line cards are synonymous, there are currently only two versions: Cisco prestandard and IEEE 802.3af compliant. Every Cisco Catalyst 4500 Series chassis and PoE power supply supports the IEEE 802.3af standard and the Cisco prestandard power implementation, helping ensure backward compatibility with existing devices powered by Cisco. All IEEE 802.3af-compliant line cards can distinguish an IEEE or Cisco prestandard powered device from an unpowered network interface card (NIC), helping ensure power is applied only when an appropriate device is connected.
Cisco Catalyst 4500 Classic Fast Ethernet and Gigabit Line Cards
The Cisco Catalyst 4500 Series offers a variety of classic 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 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.
Features and Benefits
Functionally Transparent
Cisco Catalyst 4500 Series switches offers an extensive line of modules that support numerous speeds and physical media combinations. These line cards are functionally transparent; all the packet processing, queuing, buffering, and QoS occur in the supervisor engine. To that end, both classic and E-Series line cards acquire the features and capabilities of the installed supervisor engine. For example, a classic line card previously deployed with a classic supervisor engine using 4 queues per port will automatically have capability for 8 queues per port (first half CY2008) if redeployed with a Supervisor Engine 6-E. This architecture enables customers to easily upgrade all Ethernet line cards on their Cisco Catalyst 4500 Series systems to higher-layer switching functions by adding a new supervisor engine. The simple design of the line cards results in a very high mean time between failures (MTBF), helping ensure high availability for a single connection to an end user.
Modular Versatility
The Cisco Catalyst 4500 Series is a centralized architecture that is designed to provide dedicated wire-speed bandwidth to each line-card slot within the chassis. Each line card has a dedicated bandwidth to the supervisor engine for packet processing. All network data that flows into the Cisco Catalyst 4500 Series through the various line cards goes through the supervisor engine for processing, even in single-slot port-to-port communications. All line cards have some per slot bandwidth that allows network administrators to design a system that offers full dedicated bandwidth-to-server and switch-to-switch applications and still provide high performance over subscribed gigabit to the desktop.
A modular centralized design allows customers to use their investment in high-performance line cards across the entire line of Cisco Catalyst 4500 Series chassis and supervisor engines. For example, line cards that shipped with the original Cisco Catalyst 4003 Switch in 1999 will work in the Cisco Catalyst 4500 E-Series chassis. Because of the centralized architecture of the Cisco Catalyst 4500, all line cards deployed in a chassis benefit from the enhanced features the supervisor engine provides including Security, QoS, Layer 2/3/4 routing, and hardware-based IPv6.
Following are descriptions of line cards that are available for Cisco Catalyst 4500 Series switches.
