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.
This chapter is a functional overview of the 3500 XL switches. The following topics briefly

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.
When connected to another device, a 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. Ports can also be explicitly set to operate in any
combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. In all cases, the attached
device must be within 100 meters of the switch.

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.
Note This is not a recommended configuration.
Amber
RPS is connected but not functioning properly. One of the power supplies
in the RPS could be powered down, or a fan on the RPS could have failed.
Note If you are using an RPS with a revision level lower than Z3 with a
Catalyst 3508G or a Catalyst 3548 XL switch, the switch RPS LED might
display amber (normally indicating an RPS malfunction) even when the
RPS is functioning properly. The LEDs display correctly for RPS revision
level Z3 or later. The label on the bottom of the RPS shows the revision level.
Port Mode and Port Status LEDs
Catalyst 3500 XL switches have four LED modes, each providing different information
about a particular port or about the switch itself. The Mode button (shown in Figure 1-6 and
Figure 1-7) and the Mode label (shown in Figure 1-8) highlights each mode in sequence.
Overview 1-13
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.

Flashing green
Activity; port is transmitting or receiving data.
Alternating green-amber
Link fault. Error frames can affect connectivity, and errors
such as excessive collisions, CRC errors, and alignment and
jabber errors are monitored for a link-fault indication.
Solid amber
Port is not forwarding. Port was disabled by management or an
address violation or was blocked by Spanning-Tree Protocol
(STP).
Note After a port is reconfigured, the port status LED can
remain amber for up to 30 seconds as STP checks the switch for
possible loops.
UTL (utilization)
Green
The LEDs display backplane utilization on a logarithmic scale.
If all port status LEDs are green, the switch is using 50% or
more of its total bandwidth capacity. If the right-most LED is
amber, the switch is using less than 50% of its total bandwidth.
If the LED to the left of the right-most LED is amber, the
switch is using less than 25% of its total capacity, and so on.
See Figure 1-10, Figure 1-11, and Figure 1-12 for details.

If all port status LEDs on the Catalyst 3548 XL are green, the switch is using 50% or more
of its total bandwidth capacity. If all 10/100 port status LEDs are green and the lower GBIC
LED is amber, the switch is using between 25% and 50% of its total bandwidth. If all
10/100 port status LEDs are green and if both the GBIC LEDs are amber, the switch is
using less than 25% of its total capacity, and so on.
Rear-Panel Description
Switch rear panels have an AC power connector, an RPS connector, and an RJ-45 console
port (see Figure 1-13, Figure 1-14, and Figure 1-15). These components are described in
this section.
Power Connectors
You can provide power to the switch either by using the internal power supply or by
connecting the Cisco RPS to the switch RPS connector. The internal power supply is an
autoranging unit that supports input voltages between 100 and 240 VAC. If you plan to use
the internal power supply, use the supplied AC power cord to connect the AC power
connector to an AC power outlet.
Overview 1-17
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. Use a one-to-one cable (one connector at each cable end) to connect
four external devices to the four DC output power modules. The power source is
quasi-redundant because there are two AC input power modules for the Cisco RPS and one
DC output power module for each external device. The AC input to the Cisco RPS is fully
redundant, but the DC output to the external devices is not.
For more information on the Cisco RPS, refer to the Cisco RPS documentation.
Console Port
You can connect a 3500 XL switch to a PC or terminal by means of the console port and
the supplied rollover cable. For the data characteristics of the console port, see the
“Connecting a Terminal or PC to the Console Port” section on page 2-20.

Management Options
Catalyst 3500 XL switches offer several management options:
•
Cisco Visual Switch Manager (CVSM) application
Using CVSM, you can use a Web browser to manage a switch, to display network maps,
and to monitor the network. See the Cisco IOS Desktop Switching Software
Configuration Guide and the online help in the CVSM application for more information.
•
Cluster Management application
Switches using Cisco IOS Release 12.0(5)XP software are command-capable and can
also be cluster member switches. If your switch is a cluster member or a command
switch, you can use cluster management software. See the Cisco IOS Desktop Switching
Software Configuration Guide and the online help in the cluster management
application for more information.
•
Cisco IOS command-line interface (CLI)
You can access the CLI by connecting a PC or terminal directly to the console port on
the rear panel of the switch. If the switch is connected to your network, you can use a
Telnet connection to manage the switch from a remote location. See the Cisco IOS
1-20
Catalyst 3500 Series XL Installation Guide
Deployment Strategies
Desktop Switching Command Reference for more information.
•
CiscoView application
The CiscoView device-management application displays the switch image that you can
use to set configuration parameters and to view switch status and performance
information. The CiscoView application, which you purchase separately, can be a
standalone application or part of an SNMP network-management platform. See the
CiscoView documentation for more information.
•
Simple Network Management Protocol (SNMP) network management
You can manage switches by using an SNMP-compatible management station running
platforms such as HP OpenView or SunNet Manager. The switch supports a
comprehensive set of MIB extensions and MIB II, the IEEE 802.1D bridge MIB, and
four Remote Monitoring (RMON) groups. See the documentation that came with your
SNMP application for more information.
Deployment Strategies
This section provides examples of how you could deploy the 3500 XL switches in your
network.

enterprise switch (such as the Catalyst 8500). The two Catalyst 2900 XL or 3500 XL
switches are daisy-chained together using GigaStack GBICs in half-duplex mode, creating
an 1-Gbps independent stacking backplane. In this deployment, the uplink from the
Catalyst 3508G XL is either a Gigabit EtherChannel or a 1000BaseX connection.

Figure 1-17 shows a Catalyst 3508G XL aggregating traffic from two 2900 XL or 3500 XL
switches to an enterprise switch (such as a Catalyst 8500). In this deployment, the
full-duplex connection is either a GigaStack GBIC or a 1000BaseX connection, and the
uplink is either a 1000BaseX or a Gigabit EtherChannel connection.
