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.

Switch Components

This section describes the hardware components.

Traffic Ports on the Catalyst 4948

There are 48 10/100/1000BASE-T Ethernet ports using RJ-45 interfaces and four 1000BASE-X Ethernet ports using SFP interfaces. These SFP ports share MAC addresses with the last four 10/100/1000BASE-T ports. The interface configuration mode command media-type sfp | rj45 can be used to configure the media type for these ports in the switch software and to determine whether the SFP connector or the RJ-45 connector is used. The default is SFP.

Traffic Ports on the Catalyst 4948-10GE

There are 48 10/100/1000BASE-T Ethernet ports using RJ-45 interfaces and two 10-Gigabit Ethernet uplink ports using X2 interfaces.

Switch Components

Traffic Ports on the Catalyst 4928-10GE

There are 28 1000BASE-X Ethernet ports using SFP interfaces.

Console Port

A console serial port (RJ-45) provides for switch management using standard console equipment. (See

Appendix A, “Specifications,” for the console and management ports.

The Management port on the front panel is only operational when the switch is in rommon mode. When in use, it offers the same TCP/IP based management services available using inband access (Telnet, SNMP, etc.). IP address configuration using BOOTP is supported on the Management port; it also supports image download to the switch.

Figure 1-4 and Figure 1-5 show the location of the management and console ports

on the switches.
