CHAPTER 1: WX SWITCH OVERVIEW

Management
Features

Serial console port—The serial console port provides a direct
management connection to a WX switch’s command-line interface
(CLI). The port has a DB-9 female connector and supports the
EIA-232D signaling standard.

10/100 out-of-band management port—The WX2200 switch features
an out-of-band management port, which allows you to connect the
switch to a network server and configure the switch to boot using a
software image downloaded from the server. The WXR100 also
supports booting with a software image downloaded from a server.

CAUTION: The Fn switch on the WXR100 performs two functions. If you
press the Fn switch for less than 5 seconds, it restarts the WXR100 and
reloads its configuration from the configuration file. However, if you
press the switch for 5 seconds or longer, the configuration file is deleted
and the switch restarts with its factory default settings. If you accidentally
press the Fn switch for too long and erase the configuration, you can use
the Web Quick Start to reconfigure the switch.

Power Features

Status LEDs—The Ethernet ports and power supplies have LEDs that
indicate their status. The management CPU on a WX4400 or WX2200
switch also has an LED. (For details, see “WX1200, WX4400, and
WX2200 Status LEDs” on page 16.)

Flash card slot (WX4400 only)—The flash card slot is not used for
normal WX operation.

Power supplies—A WX4400 switch comes with one 100-240 VAC
autosensing AC power supply. You can add a second supply for load
sharing and redundancy. The power supplies are hot-swappable.
A WX1200 switch contains one 100-120 VAC / 200-240 VAC
autosensing AC power supply. The WX1200 power supply is a
fixed-configuration supply and cannot be inserted or removed.
A WX2200 switch contains two 100-240V VAC autosensing AC
power supplies.
A WXR100 switch uses an external power supply, which comes with
the switch.

Hardware Features

Network Interfaces

10/100 Ethernet ports—A WXR100 switch has two 10/100BASE-TX
Ethernet ports. A WX1200 switch has eight 10/100BASE-TX Ethernet
ports. Each port has a standard RJ-45 connector and uses Category 5
(Cat 5) cable based on the EIA/TIA-586 standard.
On the WXR100, port 2 can be configured for MAP access points and
can support Power over Ethernet (PoE). Port 1 is an uplink port only
and does not support PoE.
On the WX1200, ports 1 through 6 can be configured for MAP access
points and can support PoE. Ports 7 and 8 on the WX1200 switch are
uplink ports only and do not support PoE.
The 10/100 Ethernet ports on the WX1200, WX2200, and WXR100
switches provide automatic MDI/MDX, which automatically crosses
over the send and receive signals if required.
The WX4400 and WX2200 switches provide high-bandwidth
centralized control of many indirectly connected MAP access points.
The WX4400 switch does not have 10/100 Ethernet ports and does
not provide PoE. The WX2200 has one 10/100 Ethernet port (port 3);
this port does not provide PoE.

Gigabit interface converter (GBIC) slots (WX4400 only)—A WX4400
switch has four ports. Each port has a slot for a 1000BASE-SX or
1000BASE-LX fiber-optic GBIC, and a built-in 1000BASE-TX copper
interface with an RJ-45 connector. Only one interface, copper or fiber,
can be active on a port. The GBIC interface is active by default.

Miniature Gigabit interface converter (mini-GBIC) slots (WX2200
only)—A WX2200 switch has two slots allowing insertion of small
form-factor pluggable (SFP) 1000Base-SX, 1000Base-LX, 1000Base-T,
or 1000Base-LH fiber-optic mini-GBICs to provide gigabit Ethernet
interfaces to the network.
The mini-GBICs have standard SC Duplex connectors and use either
single-mode fiber (SMF) for LX or multimode fiber (MMF) for SX.
Mini-GBICs are available separately and are not included with the
switch.
The gigabit Ethernet ports operate at 1000 Mbps only. They do not
change speed to match 10-Mbps or 100-Mbps links.

CHAPTER 1: WX SWITCH OVERVIEW

WX1200, WX4400,
and WX2200 Status

Software Features

Management
Features

Layer 2 Switching
Features

Mobility System Software (MSS) provides a combination of standard
wired LAN features and wireless LAN features that enable you to
integrate the switch into your wired network and provide network access
for wired or wireless users.

Serial and network command-line interface (CLI) access—You can
access the CLI through a direct serial connection or through the
network using Secure Shell (SSH) or Telnet.

3Com Wireless Switch Manager management application—3Com
Wireless Switch Manager is an extensive GUI application for planning,
configuring, deploying, and managing a 3Com network and its users.
3Com Wireless Switch Manager uses Secure Sockets Layer protocol
(SSL) to interact with MSS.

Software and configuration management—You can store multiple
software images and configuration files in the WX switch’s nonvolatile
storage.

Web View—Web View is a Web-based application for configuring and
managing a single WX switch through a Web browser. Web View
creates a secure connection by using Hypertext Transfer Protocol over
Secure Sockets Layer (HTTPS).

Spanning Tree Protocol (STP)—MSS is 802.1D-compatible and
supports Per-VLAN Spanning Tree (PVST+). PVST+ allows a separate
spanning tree in each virtual LAN (VLAN). Optional fast convergence
features allow you to quickly resume traffic forwarding after a
topology change.

Load-sharing port groups—You can configure multiple physical ports
into a single logical link for traffic load sharing and physical link
redundancy.

Virtual LANs (VLANs)—MSS supports logical segmentation of a
switch’s ports into separate Layer 2 collision domains. A port can be a
member of one or more VLANs. Each VLAN can have its own IP
interface. MSS supports the 802.1Q tag format.

Internet Group Management Protocol (IGMP) snooping for multicast
containment—The WX switch can learn about the multicast sources
and receivers in the network and restrict forwarding for a multicast
group to the users for that group. IGMPv1 and IGMPv2 are supported.

CHAPTER 1: WX SWITCH OVERVIEW

IP Services

Authentication,
Authorization, and
Accounting

Roaming

IP interfaces—You can configure an IP interface for each VLAN.

IP ping and traceroute—You can test IP connectivity between the WX
switch and other devices.

Domain Name Service (DNS)—You can configure the switch to use
DNS servers for name resolution. You also can configure a default
domain name to append to hostnames.

Network Time Protocol (NTP)—A WX switch can sets its time and date
by polling an NTP server.

System log—A WX generates log messages to log system events. The log
messages are stored locally and also can be exported to syslog servers.

Simple Network Management Protocol (SNMP)—A WX switch can be
configured to generate SNMP traps for major system events.

802.1X—A WX switch can authenticate users based on 802.1X
protocols. Based on authentication, users are assigned VLAN
membership, access control, and roaming boundaries.

MAC authentication—If a device does not support 802.1X, you can
configure authentication based on the source MAC address to assign
VLAN membership, access control, and roaming boundaries.

Guest authentication—Guests can be authenticated by a shared set of
authorization attributes that assign VLAN membership, access control,
and roaming boundaries.

Local and remote authentication—You can authenticate users locally using
information configured on the WX switch, or use a Remote Authentication
Dial-In User Service (RADIUS) server. When you use a remote server, the WX
switch can enhance performance by performing some of the AAA tasks
locally or distributing the load across multiple servers.

MAP access point roaming—You can configure the WX switch to
allow users to roam from one MAP access point to another on the
same WX switch.

Mobility Domain™ roaming—You also can configure a group of WX
switches to allow users to roam from one switch to another.
Regardless of the wired subnet connections, each user maintains the
same IP address and session across the network.

Session management—You can display session information and
statistics for users.

Software Features

RF Management

RF Auto-Tuning—MSS can automatically assign channels and power
settings to MAP access points based on RF information collected from
the network.

Radio frequency (RF) topology—With 3Com Wireless Switch Manager,
you can verify site coverage and capacity.

Rogue detection and countermeasures—MAPs can be used to gather
RF information for validating an RF deployment plan, and for
detecting and combatting rogue access points.

User-based RF—You can gather statistics on a per-user basis as users
roam across the network.

Installing a Power
Supply in a WX4400
Switch

A WX4400 switch is shipped with a single 100-240 VAC autosensing AC
power supply. One power supply provides enough power for a fully
configured system. You can add a second power supply for load sharing
and redundancy. A WX4400 switch containing one power supply can
have the supply installed in either slot. If the switch contains two power
supplies and one supply fails, the other supply automatically takes over to
provide uninterrupted operation.
The power supplies are hot-swappable. You can remove or insert a power
supply while the other power supply is running.
Use the following procedures to install a second power supply or replace
a failed power supply.
To attach the power supply to an WXR100, see “Powering On a WX
Switch” on page 37.
