C H A PT E R 1 Overview The Catalyst 3500 series XL switches are workgroup Ethernet switches that supply Gigabit Ethernet and autosensing 10BaseT or 100BaseTX connections in individual switches and in clustered configurations. These switches—also referred to as 3500 XL switches—can be deployed as backbone switches aggregating 10/100 and Gigabit Ethernet traffic from other switches and hubs or in mixed configurations connecting hubs, switches, servers, and desktop computers or servers.

Front-Panel Description Front-Panel Description The switch front panel contains the ports and the LEDs. This section describes these features. 10/100 Ports Figure 1-2 shows the 10/100 Ethernet ports on the switches. The switch 10/100 Ethernet ports are internally switched to all other switch ports and use RJ-45 connectors and Category 5 cabling. They operate at either 10 or 100 Mbps in full or half duplex. For autonegotiation with other devices, the ports are IEEE 802.3u-compliant.

1000BaseX Ports 1000BaseX Ports The Catalyst 3508G XL switch has eight 1000BaseX Gigabit Ethernet slots, and the Catalyst 3512, 3524, and 3548 XL switches have two1000BaseX Gigabit Ethernet slots. Figure 1-2 and Figure 1-3 show the GBIC slots for the switches.

1000BaseX Ports The GigaStack GBIC supports one full-duplex link (in a point-to-point configuration) or up to nine half-duplex links (in a stack configuration) to other Gigabit Ethernet devices. Using the required Cisco proprietary signaling and cabling, it operates within distances of less than 1 meter. The GigaStack GBICs can be installed in any of the GBIC slots on the 3500 XL switches.
Front-Panel Description LEDs You can use the switch LEDs described in this section to monitor switch activity and its performance. Figure 1-6, Figure 1-7, and Figure 1-8 show the location of the LEDs and the Mode button that you use to select one of the port modes. Changing a port mode changes the information provided by each port status LED. All of the LEDs described in this section except the utilization meter (UTL) are visible on the CVSM home page and Cluster Manager page.

Table 1-3 lists the LED colors and their meanings.
LEDs RPS LED The Redundant Power System (RPS) LED shows the RPS status. Table 1-4 lists the LED colors and their meanings. Table 1-4 RPS LED Color RPS Status Off RPS is off or is not installed. Green RPS is operational. Blinking green The RPS and the switch AC power supply are both powered up. If the switch power supply fails, the switch powers down and after 15 seconds restarts, using power from the RPS. The switch goes through its normal boot sequence when it restarts.
Front-Panel Description LED modes provide the following information: STATUS The port status. This is the default mode. UTL The current bandwidth in use by the switch. DUPLEX The port duplex mode: full duplex or half duplex. SPEED The port operating speed: 10, 100, or 1000 Mbps. See Table 1-5 for a description of the LED colors and their meanings for the different modes.
LEDs Interpreting LEDs after a Mode Change When you change port modes, the meaning of LED colors also changes. Table 1-5 explains how to interpret the LED colors after you change the mode. Table 1-5 Meaning of LED Colors in Different Modes Port Mode LED Color Meaning STATUS (port status) Off No link. Solid green Link present. Flashing green Activity; port is transmitting or receiving data. Alternating green-amber Link fault.

Rear-Panel Description Note Do not connect the switch power cord to an AC outlet if the switch is also connected to a powered-up RPS. The switches do not support the fully-redundant configuration described in the RPS Documentation. The redundant-with-reboot configuration is not recommended. Warning Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS connector. The Cisco RPS provides a quasi-redundant power source for four external devices that use up to 150W DC each.
