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.

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 Features 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 15

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.

Software Features 19

Software 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.

Management

Features

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).

Layer 2 Switching

Features

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.

20 CHAPTER 1: WX SWITCH OVERVIEW

IP Services 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.

Authentication,

Authorization, and

Accounting

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.

Roaming 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 21

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.

verify a network plan for the entire 3Com network installation before

installing WX switches or MAP access points. A network plan provides the

following information:

Number of WX switches required at your site, and where to install

them

Number of MAP access points required for adequate WLAN capacity

in each coverage area, and where to install them

Configuration settings for all the WX switches and MAP access points

in the WLAN, which can be automatically deployed to the devices by

3Com Wireless Switch Manager.

(For information about installing 3Com Wireless Switch Manager and

creating and verifying a network plan, see the Wireless Switch Manager

Reference Manual.)

Installation Location WX4400 switch fans and air inlets are located on the sides of the switch.

WX1200 and WX2200 switch fans are located in the rear of the switch and

air inlets are located on the sides of the switch. In the WX4400 switches,

separate power supply fans are located on the front. Make sure these areas

have adequate ventilation after installation. Do not block air vents.

WARNING: The WX switch has been designed and tested to be installed

in an operating ambient temperature of 0° C to +50° C (32° F to 122° F).

To reduce the risk of equipment damage, install equipment with

consideration to these ambient conditions.

WARNING: Do not stack WXR100 switches. Stacked WXR100 switches can

overheat and cause loss of equipment functionality or permanent damage.

WARNING: Ensure adequate airflow around WXR100 switches. The

WXR100 switch uses natural convection cooling and requires free entry

of air. Airflow blockage can cause the system to overheat and result in a

loss of equipment functionality or permanent damage.

Installation Requirements and Recommendations 27

The WX1200 supports 10/100 Ethernet connections. Table 8 lists the link

type and properties of the supported connections.

10/100 Ethernet Cable Wiring Connections on the 10/100 ports

require Category 5 (Cat 5) cable based on the EIA/TIA-586 standard. For

direct connection to a MAP access point, a router, or an end station such

as a PC, printer, or server, use a straight-through cable. For direct

connection to another switch, use a crossover cable. (The 10/100

Ethernet ports on the WX1200 switch provide automatic MDI/MDX,

which automatically crosses over the send and receive signals if required.)

Table 9 on page 28 lists the pin signals for 10/100 Ethernet

straight-through wiring. Pins 4, 5, 7, and 8 are used only when Power

Installing a WX

Switch

You can mount a WX1200, WX4400, or WX2200 switch in a standard

48.26-cm (19-inch) equipment rack or on a tabletop. Each switch is

shipped with two brackets for rack mounting and four adhesive rubber

feet for tabletop mounting. The WX4400 mounting brackets support

either front or center mounting. The WX1200 and WX2200 mounting

brackets support front mounting only.

The WXR100 switch does not have rack mounting brackets but can be

installed on a tabletop.

To install a WX switch, use one of the following procedures.

WARNING: Earth grounding is required for a WX switch installed in a

rack. If you are relying on the rack to provide ground, the rack itself must

be grounded with a ground strap to the earth ground. Metal screws

attaching the switch to the rack provide ground attachment to the rack.

WARNING: In the U.S., overcurrent protection must be provided by the

installation. Branch circuit protection in accordance with National Fire

Protection Association (NFPA) 70, National Electrical Code (NEC) is

required. Consideration must be given to the electrical ratings on the WX

switch and branch circuit protection. Do not install equipment such that

the branch circuit current and voltage protection is exceeded. Pay

particular attention to the earthing connection for the supply

connections. When using an extension cord or power strip, pay attention

to the grounding type.

CAUTION: Do not stack WXR100 switches. Stacked WXR100 switches can

overheat and cause loss of equipment functionality or permanent damage.

CAUTION: Ensure adequate airflow around WXR100 switches. The

WXR100 switch uses natural convection cooling and requires free entry

of air. Airflow blockage can cause the system to overheat and result in a

loss of equipment functionality or permanent damage.

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.

BWX TROUBLESHOOTING

Table 15 contains remedies for some common problems that can occur

during basic installation and setup of a WX switch.

Tabl e 15 WX Setup Problems and Remedies

Symptom Diagnosis Remedy

3Com Wireless

Switch Manager or

a web browser (if

you are using Web

View) warns that

the WX switch’s

certificate date is

invalid.

The switch’s time and date

are currently incorrect, or

were incorrect when you

generated the self-signed

certificate or certificate

request.

1Use set timezone to set the

time zone in which you are

operating the switch. (See

“Setting the Time Zone” in

the Wireless LAN Switch and

Controller Configuration

Guide.)

2Use set timedate to

configure the current time

and date in that time zone.

(See “Statically Configuring

the System Time and Date”

in the Wireless LAN Switch

and Controller Configuration

Guide.)

3Reconfigure the

administrative certificate(s).

(See “Creating Keys and

Certificates” in the Wireless

LAN Switch and Controller

Configuration Guide.)

4If you have already

configured a certificate on

the switch for authentication

by network users, you must

recreate this certificate, too.

54 CHAPTER B: WX TROUBLESHOOTING

WX switch does not

accept

configuration

information for an

MAP access point or

a radio.

The country code might

not be set or might be set

for another country.

1Type the display system

command to display the

country code configured on

the switch.

2If the value in the System

Countrycode field is NONE or

is for a country other than

the one in which you are

operating the switch, use the

set system countrycode

command to configure the

correct country code. (See

“Specifying the Country of

Operation” in the Wireless

LAN Switch and Controller

Configuration Guide.)

Client cannot access

the network.

This symptom has more

than one possible cause:

The client might be

failing authentication or

might not be

authorized for a VLAN.

1Type the display aaa

command to check the

authentication rules on the

WX switch, to ensure that

the client can be

authenticated.

2Check the authorization rules

in the switch’s local database

(display aaa) or on the

RADIUS servers to ensure the

client is authorized to join a

VLAN that is configured on at

least one of the WX switches

in the Mobility Domain.

If the client and switch

configurations are

correct, a VLAN might

be disconnected. A

client connected to a

VLAN that is

disconnected is unable

to access the network.

1Type the display vlan

config command to check

the status of each VLAN.

2If a VLAN is disconnected

(VLAN state is Down), check

the network cables for the

VLAN’s ports. At least one of

the ports in a VLAN must

have a physical link to the

network for the VLAN to be

connected.

Table 15 WX Setup Problems and Remedies (continued)

Symptom Diagnosis Remedy

55

Configuration

information

disappears after a

software reload.

The configuration changes

were not saved.

1Retype the commands for the

missing configuration

information.

2Type the save config

command to save the

changes.

Mgmt LED is quickly

blinking amber.

CLI stops at boot

prompt (boot>).

The WX switch was unable

to load the system image

file.

Type the boot command at the

boot prompt.
