Cisco Catalyst 4500 Series line Card

Fast Ethernet and Gigabit Ethernet line cards

The Cisco Catalyst 4500 series scalable, modular, and high-density switches provide superior combined second-layer switching and intelligent services, which enable network control and sustainability. These switches provide a wide range of Fast Ethernet and Gigabit Ethernet line cards, including the desktop, branch backbone and servers for enterprise and commercial Exchange solutions, and the fiber and copper interfaces optimized for service Supply mall domain Ethernet. Gigabit Ethernet line cards include cost-effective high-performance 1000base-x Gigabit Interface Converters (GBIC), small pluggable (SFP) Gigabit Ethernet, and high-density 10/100/1000base-t three-speed automatic, automated negotiation Gigabit Ethernet line cards. Fast Ethernet wire cards include a variety of wire speed 10/100, 100-FX, 100base-lx10 and 100base-bx-d densities.

Ethernet Power Cable Card

The Cisco Catalyst 4500 series provides the cards, power supplies, and accessories needed to deploy and operate a standard Ethernet power (PoE) network interconnect. When connecting an IEEE 802.3AF standard or a Cisco pre-standard electrical device to a Poe line card, Poe provides the –48 VDC power on the standard category 5th unshielded twisted pair (UTP) cable up to 100 m. IP telephony, wireless base stations, cameras, and other IEEE-compliant port-connected devices do not require wall power, and can be powered by using the Cisco Catalyst 4500 series Poe line card. This feature enables network administrators to centrally control the power supply without having to install a socket in the ceiling and other places where electrical equipment may be installed.

Despite all the synonyms, such as "PoE", "feeder power" and "voice" power and line cards, there are still two versions: Cisco pre-Standard and IEEE 802.3AF standard version. Each Cisco Catalyst 4500-Series chassis and Poe Power supply support the IEEE 802.3AF standard, while Cisco pre-standard power implementation ensures backward compatibility with existing Cisco-powered devices. All line cards that conform to the IEEE 802.3AF standard can differentiate between IEEE or Cisco pre-standard electrical and not-equipped network interface cards (NICs), and ensure that power is only available when the appropriate device is connected.

First Mile Ethernet

Cisco Catalyst 4500 Series line cards for first-mile Ethernet (EFM) to meet the high, high bandwidth and long-distance requirements of network operators to build next-generation metropolitan area networks. The Cisco Catalyst 4500 series EFM Card enables service providers to provide a combination of data, voice, and video services for families, business areas, and multi-tenant units on a single optical connection. EFM wire cards are also used in manufacturing plants, traffic monitoring and desktop optical applications. Fiber-optic Ethernet can support operations in noisy electromagnetic environments, providing physical security and longer distances with equally easy to understand Ethernet transmissions. EFM line cards include 1000-base-x, 100-FX, 100base-lx10, and 100base-bx-d for fibre options, and 10/100 or 10/100/1000base-t line cards for copper options when using a media converter.

Features and advantages

function transparent

The Catalyst 4500 series switches provide a wide range of modules that support a combination of speed and physical media. These card functions are transparent; All packet processing, sorting, buffering, and QoS are performed in the Exchange Management engine. To do this, the wire card leverages the features and capabilities of the installed Exchange Management engine. This architecture enables all Ethernet line cards on the Cisco Catalyst 4500 system to simply add a new switching management engine, which can easily be upgraded to higher-level switching capabilities. The simple design of the wire card allows for extremely high average failure intervals (MTBF), ensuring high availability to the end user's single connection.

Modular flexibility

The Cisco Catalyst 4500 series is a centralized architecture that provides dedicated-line speed bandwidth for each card in the chassis. Each line card has a dedicated bandwidth to the swap management engine for group processing. All network data transmitted through various wire cards to the Catalyst 4500 series are processed by the Exchange Management engine even in the communication between single slot ports. All cards have a certain bandwidth per slot, allowing the network administrator to design a system that provides full dedicated server bandwidth and switch applications, and delivers high-performance, oversubscribed desktop gigabit connections.

Modular centralized design allows customers to take advantage of the high performance of their online card investments, which apply to the entire Catalyst 4500 chassis family and the switching management engine. For example, the initial Catalyst 4003 switch is equipped with a wire card that can be installed in the new Engine 4500 series running Cisco Catalyst 4500 Supervisor Catalyst v.
