THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

•Turn the television or radio antenna until the interference stops.

•Move the equipment to one side or the other of the television or radio.

•Move the equipment farther away from the television or radio.

•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Product Overview

This chapter describes the Catalyst 4900M switch, as well as system features and components.

This chapter contains these sections:

•Catalyst 4900M Switch Applications, page 1-1

•Catalyst 4900M Switch Software Features, page 1-6

•Hardware System Features, page 1-6

•Switch Components, page 1-7

Catalyst 4900M Switch Applications

The Catalyst 4900M switch (see Figure 1-1) is designed for top-of-rack server aggregation. It simplifies the transition from 1 GB to 10 GB attached devices in the data center. The Cisco Catalyst 4900M is a top of rack Ethernet switch optimized for mixing 10/100/1000 and 10 Gigabit Ethernet access devices. It is a fixed Cisco IOS based Layer 2+ switch with 8 fixed wire speed X2 ports on the base unit with 2 optional half card slots. The half card slots can accommodate the following cards in any combination:

•20-port wirespeed10/100/1000 (RJ-45) half card

•4-port wire speed 10GbE (X2) half card

•8-port (2:1) 10GbE (X2) half card (Twin Gig compatible)

		Cisco Catalyst 4900M Switch Installation Guide
	78-18350-01			1-1

Chapter 1 Product Overview

Catalyst 4900M Switch Applications

The half cards provide a wide variety of combinations of Gigabit Ethernet and 10 Gigabit Ethernet media types. The half slots also provide investment protection for further additions of 1 GE and 10 GE media.

Chapter 1 Product Overview

Catalyst 4900M Switch Software Features

Note When using TwinGig and X2 transceivers on this module, keep them grouped in pairs as follows: 1-2, 3-4, 5-6, 7-8. Inserting a TwinGig or X2 transciever in any port will affect the capabilities of its partner port, and both will be set to handle the same type automatically. Mixing within a port group will not work. As an example, you would not be able to have an X2 in port 1 and a TwinGig in port 2 and expect both of them to function.

The Catalyst 4900M switch has a 320-Gbps, nonblocking, full-duplex switching fabric, providing 250 million packets-per-second of switching capacity for high-speed applications. The Catalyst 4900M chassis has eight 10 Gigabit Ethernet ports and other ports as configured.

A removable automatic variable speed fan tray for low-noise operation at room temperature and removable and redundant 1000 W AC or 1000 W DC power supplies provide fault-tolerance protection for the switch. See the “Connecting Power to the Catalyst 4900M Switch” section on page 3-11.

Catalyst 4900M Switch Software Features

For up-to-date information on software features, refer to the release notes and software configuration guide for your software release.

Hardware System Features

The Catalyst 4900M switch is a high-performance dedicated Ethernet switch that fully integrates into the Catalyst family of switches using Catalyst 4500 series system software.

The following is an overview of the Catalyst 4900M hardware features:

•Eight 10 Gigabit Ethernet uplink ports using X2 interfaces

•Serial console management port using an RJ-45 interface

•A removable automatic variable speed fan tray for low-noise operation at room temperature

•Redundant and removable 1000 W AC or DC power supplies

Switch Components

•512-MB SDRAM (fixed)

•128-MB embedded Flash memory

•360-Gbps switching capacity, 250 million packets-per-second actual forwarding rate

•EtherChannel at 10/100/1000 Mbps, as well as 10 Gbps

•Host and device USB 2.0 ports

•Compact flash memory slot

Switch Components

This section describes the Catalyst 4900M hardware components.

Traffic Ports

There are eight 10-Gigabit Ethernet uplink ports using X2 interfaces and other traffic ports depending on the switching modules installed.

TwinGig Modules

On the WS-4908-10GE modules only, TwinGig converter modules may be used in place of X2 modules if you need to provide 1 GB SFP connections. When you insert the TwinGig into one port, its neighbor automatically converts to 1 GE interfaces whether it has a TwinGig installed or not, so you need to group your TwinGigs next to one another. The neighboring port to a TwinGig port cannot support an X2.

Installation documentation for Cisco TwinGig converter modules can be found at:

Switch Components

Rear Chassis Connections and Features

The Reset button is used to restart the switch. Use a paper clip or other small, pointed object to press the Reset button.

A console serial port (RJ-45) provides for switch management using standard console equipment. (See Figure 1-5.) A connector pinout table is provided in Appendix A, “Specifications,” for the console and management ports.

The Management port on the rear panel offers the same TCP/IP based management services available via inband access (telnet SNMP etc.). IP address configuration via BOOTP is supported on the Management port; it also supports image download to the switch.

A USB connector is provided for future expansion.

The Compact Flash port accepts both 64-MB and 128-MB Type 1 compact Flash cards. You can use it for file transfer tasks such as loading a new software image. The Flash card is optional and can be obtained from third-party suppliers.

For more information, refer to Using the Compact Flash on the Catalyst 4500 Series Supervisor Engines at the following URL:
