C H A P T E R 1 Overview The Catalyst 2900 series XL modules add port density and high-performance connectivity to a Catalyst 2900 series network. When installed in the appropriate Catalyst 2900 series switch, these modules support a full range of cabling types, port connectors, and 10, 100, and 1000 megabit-per-second (Mbps) transmission speeds. All the Catalyst 2900 series modules autonegotiate the duplex mode of each port to match that of the attached device.

The port supports the IEEE 802.3z 1000BaseX standard.
Chapter 1 Overview Key Features GBICs for the 1000BaseX Module You can install either a short-wavelength (SX) or a long-wavelength/long-haul (LX/LH) GBIC into the 1000BaseX module. Figure 1-5 shows a GBIC, and the GBIC types are listed in Table 1-2.

The 1000BaseT module port supports the IEEE 802.3ab standard.
Chapter 1 Overview LEDs LEDs An LED above or next to each port reflects the port status, as described in Table 1-3. Table 1-3 Port LEDs Color Meaning Off No link. Green Link present. Flashing green Activity; port is transmitting or receiving data. Alternating green-amber The port is experiencing error frames that can affect connectivity. The port monitors errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment errors.
Chapter 1 Overview Cabling Guidelines The 10/100 ports are numbered 1X through 4X. The X indicates that the pins on the port connector are internally crossed. If you are connecting to a device with ports marked with an X, such as another switch or hub, use a crossover cable. If you are connecting to devices with ports not marked with an X, such as a PC, workstation, or server, use a straight-through cable.

Catalyst 2900 series switches with 10/100, 1000BaseX, and 1000BaseT modules installed connect the PCs and create a gigabit Ethernet or gigabit EtherChannel link to an ultra-high-performance server supporting the Fast EtherChannel feature.
Chapter 1 Overview Deployment Examples Wiring Closet Aggregator Figure 1-9 shows a Catalyst 2924M XL switch aggregating traffic from shared 10BaseT, switched 100BaseTX, and switched 10BaseT networks. A 100BaseFX module passes the traffic to a backbone switch or router, and a 10/100 module links the switch through a Fast EtherChannel link to a high-performance server.
Chapter 1 Overview Deployment Examples Fast or Gigabit EtherChannel Backbone Figure 1-10 shows three Catalyst 2924M XL switches creating a high-speed backbone for 10/100 PCs, Catalyst 2820 or Catalyst 1900 series switches, and stacked FastHub 100BaseTX repeaters.
