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.

Features

The switches are stackable 10/100 Ethernet switches to which you can connect workstations, Cisco IP Phones, and other network devices such as servers, routers, and other switches. The 2900 XL LRE switches employ Long-Reach Ethernet (LRE), a very-high-data-rate digital subscriber line (VDSL)-based technology that allows an Ethernet network to reach distances up to 4921 feet (1500 meters). The switches can be deployed as backbone switches, aggregating 10/100 and Gigabit Ethernet traffic from other network devices.

The Catalyst 2900 XL switches have these features:

•Autonegotiates speed and duplex operation on all 10/100 ports

•Operates in full-duplex mode on all 100BASE-FX ports

Management Interface Options

The Catalyst 2900 XL and Catalyst 3500 XL switches are designed for plug-and-play operation: you only need to assign basic IP information to the switch and connect it to the other devices in your network. If you have specific network needs, you can configure and monitor the switch—on an individual basis or as part of a switch cluster—through its various management interfaces.

You can configure and monitor individual switches and switch clusters by using the following interfaces:

•Cluster Management Suite (CMS)—CMS is a graphical user interface that can be launched from anywhere in your network through a web browser such as Netscape Communicator or Microsoft Internet Explorer. CMS is already installed on the switch, and no additional installation is required. Using CMS, you can fully configure and monitor a standalone switch, a specific cluster member, or an entire switch cluster. You can also display network topologies to gather link information, and display switch images to modify switchand port-level settings.

•Command-line Interface (CLI)—The switch CLI Cisco IOS software and is enhanced to support desktop-switching features. You can fully configure and monitor the switch and switch cluster members from the CLI. You can access the CLI either by connecting your management station directly to the switch console port or by using Telnet from a remote management station.

•Simple network management protocol (SNMP)—SNMP provides a means to monitor and control the switch and switch cluster members. You can manage switch configuration settings, performance, security, and collect statistics by using SNMP management applications such as CiscoWorks2000 LAN Management Suite (LMS) and HP OpenView.

You can manage the switch from an SNMP-compatible management station that is running platforms such as HP OpenView or SunNet Manager. The switch supports a comprehensive set of MIB extensions and four Remote Monitoring (RMON) groups.

For more information about CMS, the CLI, and SNMP refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

The 10/100 switch ports (see Figure 1-2 and Figure 1-4) can connect to any compatible network device up to 328 feet (100 meters) away:

•10BASE-T-compatible devices, such as workstations, Cisco IP Phones, and hubs through standard RJ-45 connectors and Category 3, 4, or 5 cabling

•100BASE-TX-compatible devices, such as high-speed workstations,

Cisco IP Phones, servers, hubs, routers, and other switches through standard RJ-45 connectors and Category 5 cabling

Note A Category 5 cable is required for 100BASE-TX traffic. A port operating at 10BASE-T can use Category 3 and 4 cables.

When connecting the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the cable is a straight-through, twisted-pair cable. When connecting the switch to switches or hubs, use a crossover cable. Pinouts for the cables are described in Appendix B, “Connectors and Cable Specifications.”

The 10/100 switch ports can be explicitly set to operate in any combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. These ports also can be set for speed and duplex autonegotiation, compliant with IEEE 802.3u. When set for autonegotiation, the port senses the speed and duplex settings of the attached device and advertises its own capabilities. If the connected device also supports autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that both devices support and full-duplex transmission if the attached device supports it) and configures itself accordingly.

Chapter 1 Product Overview

100BASE-FX Ports

The 10/100 ports on the Catalyst 2900 XL switches provide protocol support for Cisco IP Phones and per-port priority override. Refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide for more information about these features.

Cisco IP Phones—connected to the 10/100 port—must be connected to an AC power source. Unlike the 3524-PWR XL switch, the Catalyst 2900 XL switches do not provide inline power.

For more info on the Catalyst 3524-PWR XL switch, refer to the

Catalyst 3500 Series XL Hardware Installation Guide.

100BASE-FX Ports

The 100BASE-FX ports use 10/125or 62.5/125-micron multimode fiber-optic cabling. The connection distances between the switch and the attached device can be as follows:

•If the switch port and the port on the attached device are configured for half-duplex operation, the connection can be up to 1352 feet (412 meters).

•If the switch port and the port on the attached device are configured for full-duplex operation, the connection can be over distances of up to 6562 feet (2 kilometers).

Long-Reach Ethernet Ports

The Long-Reach Ethernet (LRE) ports (Figure 1-4) use one RJ-21 connector to connect up to 24 Cisco 575 LRE customer premises equipment (CPE) devices though unstructured wiring, such as existing telephone lines. The link between the LRE switch port and each CPE device can reach speeds of up to 15 Mbps (full duplex) and distances of up to 4921 feet (1500 meters).

The default mode for each LRE port is speed autonegotiation, half duplex operation. For information about configuring the LRE ports, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

For more information about the Cisco 575 LRE CPE, refer to the Cisco 575 LRE CPE Hardware Installation Guide.

Chapter 1 Product Overview

100BASE-FX Ports

If telephone services, such as voice or integrated services digital network (ISDN), use the same cabling as LRE traffic, the LRE port must be connected to the patch panel through a basic telephone service, also known as plain old telephone service (POTS) splitter. The splitter routes LRE data (high-frequency) and voice (low-frequency) traffic from the telephone line to the switch and private branch exchange (PBX) switch or public-switched telephone network (PSTN)

If the other telephone services are connected through a private branch exchange (PBX) switch, a Cisco LRE 48 POTS Splitter can be used. The PBX routes voice traffic to private telephone networks and the public system telephone network (PSTN). For more information about the Cisco LRE 48 POTS Splitter (PS-1M-LRE-48), refer to the Installation Notes for the Cisco LRE 48 POTS Splitter.

If the installation does not have a PBX, a homologated POTS splitter is required to directly connect to the PSTN. For more information about homologated POTS splitters, contact your Cisco sales representative.

Note If a connection to a phone network is not required at all, a splitter is not needed, and the switch can connect directly to the patch panel.

Expansion Slots

The expansion slots (see Figure 1-2) are for the Catalyst 2900 XL hot-swappable modules. Each module port is internally switched to other switch ports and is managed through the switch management interfaces.

Table 1-1 lists the modules that the expansion slots support.

These modules automatically configure themselves when you insert them in expansion slots and tighten the thumb screws. A power-on self-test (POST) verifies that the module is working properly before it starts forwarding packets.

Modules WS-X2914-XL and WS-X2922-XL support 2048 MAC addresses. If you install one of these modules in a 2924M XL or Catalyst 2912MF XL switch (both supporting 8192 MAC addresses), the module fails POST. You can start the module by restarting the switch with the module installed. After the restart, the switch address capacity is reduced to 2048 MAC addresses.

See the Catalyst 2900 Series XL Modules Installation Guide and the

Catalyst 2900 Series XL ATM Modules Installation and Configuration Guide for detailed information on expansion modules for Catalyst 2900 series XL switches.

LEDs

You can use the switch LEDs to monitor switch activity and its performance. Figure 1-5, Figure 1-6, and Figure 1-7 show the location of the LEDs and the Mode button that you use to select a port mode. Changing a port mode changes the information provided by each port LED.

All of the LEDs described in this section except the utilization meter (UTL) are visible on the Cluster Management Suite (CMS) window and, if the switch is a cluster member, on the CMS Cluster Manager window. The Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide describes how to use CMS to manage standalone or individual switches and how to use cluster management software to manage switch clusters].
