Features
Management Interface Options
The Catalyst 2900 XL and Catalyst 3500 XL switches are designed for
plug-and-play o per ation : you only ne ed to assign bas ic IP informatio n t o the
switch and connect it to the other devices in your network. If you have specific
network needs, you c an 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 m onitor individual switches and switch clusters by using
the following interfaces:
• Cluster Management Suite (CMS)—CMS is a graphical user interface that
canbelaunchedfromanywhereinyournetworkthroughawebbrowsersuch
as Netscape Communicator or Microsoft Internet Explorer. CMS is already
installedontheswitch,andnoadditionalinstallationis required.UsingCMS,
you can fully configure and monitor a standalone switch, a sp ecific cluster
member,or an entire switch cluster.You can also display network topologies
to gather link information, and display switch images to modify switch- and
port-level settings.
• Command-line Interface (CLI)—TheswitchCLICiscoIOSsoftwareandis
enhanced to sup port desktop- switc hing feature s. You can fully configure and
monitor th e switch a nd switch cluster m embe rs 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 manage ment station.
Chapter1 Product Overview
1-4
• Simple network managem en t protoco l (SNMP) —SNMP provides a means to
monitor and control the s witch and switch cluster members. You can manage
switch configuration settings, performance, security, and collect statistics by
using SNMP m anage men t applications such as CiscoWorks2000 LAN
Management Suite (LMS) and H P OpenView.
You can manage the switch from an SNMP-compatible management station
that is runn ing platforms such as HP Op enView or SunNet Manager. Th e
switch supports a comprehensive set of M IB extensions and f our Remote
Monitoring (RMO N) groups.
For more inform ation about CMS, the CLI, and SNMP refer to the Catalyst
2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

10/100 Ports
The 10/100 switch ports (see Figure 1-2 an d Figure 1-4) can connect to any
compatible ne twork device up to 328 feet (100 meters) away:
• 10BASE-T-compa tibl e devices, such as workstat ions, Cisco IP Phon es, and
hubs through standard RJ-45 connectors an d Category 3, 4, or 5 cablin g
• 100BASE-TX-compatible devices, such as high-speed workstations,
Cisco IP Phones, servers, hubs, router s, and oth er switch es throug h standar d
RJ-45 connectors and Category 5 cabling

Note A Category 5 cable is requir ed for 100BASE-TX traffic. A port operating at
10BASE-TcanuseCategory3and4cables.
When connecting the switch to workstations, servers, routers, and Cisco IP
Phones, be sure t hat the cable is a straight-through, t wiste d-pa ir ca ble . W hen
connecting the switch to switch es or hubs, use a crossover cable. Pinou ts fo r
the cables are described in Appendix B, “Connect ors and Cable
Specifications.”
The 10/100 switch ports c an be explicitly set to operate in any combinat ion of
half duplex, fu ll duplex, 10 Mbps, or 100 Mbps. These ports also can be set for
speed and dupl ex aut onegotia tio n, compliant with IEEE 802.3u. W he n s et f or
autonegotiation, the port senses the speed a nd duplex settings of the atta ch ed
device and advertises its own capabilities. If the connected device also supports
autonegotiation, the switch port negotiates the best con nection (that is, the fastest
line speed that both devices support and full-duplex transmission if the attached
device supports it) and configures itself accor dingly.

Chapter 1 Product Overview
The 10/100 ports on the Catalyst 2900 XL switches provide proto col sup port f or
Cisco IP Phones and per-port priority override. Refer to the Catalyst 2900 Se ries
XL and Catal yst 3500 Series XL Software Configuration Guide for more
information a bout these feature s.
Cisco IP Phones—connected to the 10/100 port—must be connected to an AC
power source. Unlike the 3524-PWR X L switch, the C atal yst 2900 XL switch es
do not provide inline power.
For more info on the Catalyst 352 4-PW R X L switch, refer to the
Catalyst 3 500 Series XL Hardware I nstallation Guide.
100BASE-FX Ports
The 100BASE-FX ports use 10/125- or 62.5/125-micron multimode fiber-optic
cabling. The connection distances between the switch and the attached device can
be as follows:
• If the swit ch port and th e port on the attached device are configured for
half-duplex ope ratio n, the connectio n can be up t o 1352 feet (4 12 meters).
100BASE-FX Ports
• If the swit ch port and th e port on the attached device are configured for
full-duplex op er ati on , the conn ec ti on can be over dis ta nces of u p to 65 62 feet
(2 kilometers).
Long-Reach Ethernet Ports
The Long-Reach Ethernet (LRE) ports (Figure 1-4) use one RJ-21 connec tor to
connect up to 24 Cisco 575 LRE customer premises equipm en t (CPE ) devices
though unstructured w iring , su ch as existing telephone lines. The link between t he
LREswitchportandeachCPEdevicecanreachspeedsofupto15Mbps(full
duplex) and dist ances of up to 4921 feet ( 1500 meters).
The default mo de for each L RE port is speed autonegotiation, half duplex
operation. For i nfor matio n about configuring the LRE ports, refer to the Catalyst
2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

Chapter1 Product Overview
If telephone services, suc h as voice or integrated serv ices digital ne twork (ISDN),
use the same cabling as LRE traffic, the L RE port must be connected to the patch
panel through a b asic telephone service, also known as plain old te lephone service
(POTS) splitter. The splitter routes LRE data (high-frequency) and voice
(low-frequency) traffic from the telephone line to t he switch and private branch
exchange (PBX) swi tch or public-switched telephone net work ( PSTN)
If the other telephone services are connected thr oug h a private branch exchan ge
(PBX) switch, a Cisco LRE 48 POTS Splitter can be used. The PBX routes voice
traffic to private tel ephon e networks and the public system t elepho ne network
(PSTN). For more information about the Cisco LRE 48 POTS Splitter
(PS-1M-LRE-48), re fer 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 d irectly con nect to the PSTN. For more information about homol ogated POTS
splitters, contact y our Cisco sales representative.

Expansion Slots
The expansion slots (see Figure 1-2) are for the Catalyst 2900 XL hot-swappable
modules. Each module port is in ternally switched to other switch ports and is
managed throu gh the switch m an agem en t 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-X29 14-XL and WS-X2922-XL support 2048 M AC addresses. If
you install one of these modul es in a 2924M XL or Catalyst 2912M F X L switch
(both su pport ing 8192 MAC addresses ), the module fails PO ST. 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.
