Trapeze Networks Mobility System

The Trapeze Networks Mobility System is a system for planning and deploying a
secure WLAN in an existing wired enterprise network. The Trapeze system
provides authenticated connectivity to both wireless and wired users in large
environments such as office buildings, hospitals, and university campuses.

The Trapeze Mobility System fulfills the three fundamental requirements of an
enterprise WLAN: It eliminates the distinction between wired and wireless
networks, allows users to work safely from anywhere (secure mobility), and
provides a comprehensive suite of intuitive tools for planning and managing the
network before and after deployment.

Cable Ports

MP access point models MP-241, MP-252, and MP-262 have two RJ-45 ports.
(See Figure 2.) Each port provides a 10/100BASE-TX Ethernet connection to an
MX switch. The connection can be direct to an MX-switch or indirect through an
intermediate Layer 2 or Layer network.

The MP receives power and data through the ports. Use a Category 5 (Cat 5) cable
with straight-through signaling and standard RJ-45 connectors to connect the MP
access point to an MX switch or other device in the network.

The two RJ-45 ports support dual-homed configurations for redundancy. An MP
uses only one link for booting, configuration, and data transfer. If the link
becomes unavailable, the MP can reboot using the other link.

The ports are identical except for logical numbering (1 or 2). You can use either
port to connect an MP access point to an MX switch. However, an MP always
attempts to boot on MP port 1 first. Only if the boot attempt on port 1 fails does
the MP attempt to boot on port 2.

If both ports are directly connected to MX switch ports supplying Power over
Ethernet (PoE), the ports load-share. If one port becomes unavailable, the other
port can provide full power to the MP.

MP model MP-52 has one RJ-45 port for direct or indirect connection to an MX
switch.

Note. MP access points do not support daisy-chain configurations. Do not

connect the MP access point to another MP access point.

External Antenna Connector

Model MP-262 has a connector for attaching an external sectorized antenna for
the 802.11b/g radio. (See Figure 2.) An external antenna is required for the

802.11b/g radio. The radio does not have an internal antenna. Table 2 lists the
MP-262 external antennas.

Connection Options

You can connect an MP access port directly to an MX switch port or indirectly to
MX switches through an intermediate Layer 2 or Layer 3 network. In either case,
use Category 5 (CAT 5) cable with straight-through signaling for each MP
connection.

For MP models with two Ethernet ports, you can provide data link redundancy by
connecting both of its ports directly to MX switch ports or indirectly to MX
switches through the network.

For all MP models, you can provide MX management redundancy even on a
single MP Ethernet port by connecting the MP indirectly to multiple MX switches
through an intermediate Layer 2 or Layer 3 network.

Note. Install the Cat 5 cables for the MP access point at the installation site

before installing the access point itself. During installation, you will insert the
Cat 5 cable(s) into the MP port(s) before attaching the access point to the
bracket.

Installation Requirements and
Recommendations

For best results, follow these requirements and recommendations before installing
an MP access point.

RingMaster Network Plan and Work Orders

If you are using RingMaster to plan your Trapeze Networks Mobility System
installation, you might want to create and verify a network plan for the entire
Trapeze network installation and generate an MP work order, before installing MP
access points. A network plan and the MP work orders generated from it provide
the following information about MP access point installation and configuration:

Chapter 3

● Number of MP access points required for adequate WLAN capacity in each

coverage area

● Detailed installation location for each MP access point

● Settings for all MP access points in the WLAN

(For information about installing RingMaster, creating and verifying a network
plan, and generating an MP work order, see the Trapeze RingMaster

Administrator’s Guide.)

Installation Requirements and Recommendations

Chapter 3

MX Switch Recommendation

Trapeze Networks recommends that you install and configure the MX switch
before installing an MP access point. If the switch is already installed and
configured for the MP access point(s), you can immediately verify the cable
connection(s) when you plug the cable(s) into the MP access point.

Caution! The MP access point is designed to receive power only from a

Trapeze Networks Mobility Exchange (MX) switch or Trapeze-approved power
injector. Connecting an MP access point to a Power over Ethernet (PoE) device
that is not approved by Trapeze Networks can damage the equipment.

(For information about connecting an MP access point to an MX switch port, see
“Connecting an MP to an MX Switch” on page 48.)

Wall Installation Recommendations

If you plan to install MP model MP-241 or MP-252 on a partial wall or other
vertical surface, orient the top of the access point (the side with the LEDs) toward
the intended coverage area. The radio antennas transmit through the top of the
access point but not through the bottom (where the bracket is). This
recommendation also applies to model MP-262 if you plan to use the 802.11a
radio.

The MP-52 and the 802.11b/g radio in the MP-262 use external antennas, which
you can orient independently of the MP itself:

● Orient an MP-262 external antenna to face the intended coverage area.

MP Radio Safety Advisories

When you enable the MP radio(s) as part of MX switch configuration, the radios
are able to receive and transmit radio frequency energy as soon as you connect the
MP access point(s) to the MX switch, either directly or through the network.

Installation Requirements and Recommendations

Radio Frequency Exposure

Federal Communications Commission (FCC) Docket 96-8 for Spread Spectrum
Transmitters specifies a safety standard for human exposure to radio frequency
electromagnetic energy emitted by FCC-certified equipment. When used with the
proper antennas (shipped in the product), Trapeze Networks MP access point
products meet the uncontrolled environmental limits found in OET-65 and
ANSI C95.1-1991. Proper installation of the MP access point according to the
instructions in this manual will result in user exposure that is substantially below
the FCC recommended limits.

Additional Radio Safety Advisories

(For translations of these warnings, see “Radio Safety Warnings” on page 68.)

Warning! In the U.S., locate the MP access point a minimum of 20 cm

(7.9 inches) away from people. This safety warning conforms with FCC radio
frequency exposure limits for dipole antennas such as those used in the MP
access point.

Warning! Do not operate the MP access point near unshielded blasting caps

or in an otherwise explosive environment unless the device has been modified
for such use by qualified personnel.

Warning! Do not touch or move the MP access point when the antennas are

transmitting or receiving.

Warning! Do not hold any radio device so that the antenna is very close to or

touching the face, eyes, or other exposed body part while the device's radio
antenna is transmitting.

Warning! Before using a wireless device in a hazardous location, consult the

local codes, national codes, and safety directors of the location for usage
constraints.

Cable Requirements

Warning! Do not connect or disconnect cables or otherwise work with the MP

access point hardware during periods of lightning activity. (For translations of
this warning, see “Lightning Warning” on page 71.)

Note. The MP access point is intended for indoor use only. Do not install the

device outdoors, unless you install it in a properly installed Trapeze Networks
outdoor MP enclosure.

Note. To reduce the possibility of connection interference caused by dust,

clean the Cat 5 connector pins before inserting a cable into an MP access point.

Cat 5 cable with straight-through signaling must be installed at the site before you
install an MP access point. A single connection requires one cable. A dual-homed
connection requires two cables.

Table 4 lists the pin signals for 10/100 Ethernet straight-through wiring. Pins 4, 5,
7, and 8 are used only when Power over Ethernet (PoE) is enabled on the port. RD
means Receive Data and TD means Transmit Data.

2 When the link is activated, observe the MP LED for the port on the MX

switch:

MP LED Appearance Meaning

Solid green For an MP access point’s active link, all the

following are true:

• MP access point has booted.

• MP access point has received a valid
configuration from the MX switch.

• Management link with an MP access point is
operational.

• At least one radio is enabled or is in sentry
mode.

For an MP access point’s secondary link, the
link is present.

Alternating green and
amber

MP access point is booting with an image
received from the MX switch. After the access
point boots and receives its configuration, this
LED appearance persists until a radio is enabled
or is placed in sentry mode.

Solid amber PoE is on.

Blinking amber MP is unresponsive or there is a PoE problem.

Unlit PoE is off.

Note. An MX switch’s 10/100 Ethernet ports are configured as wired network

ports by default. You or the system administrator must change the port type for
an MX port directly connected to an MP to activate the link. (See the Trapeze

Mobility Exchange Installation and Basic Configuration Guide.)

Verifying MP Health

After you install the MP access point and enable PoE on the Ethernet cable
connected to the MP, you can easily verify the MP’s status by observing the LEDs,
particularly the health LED. (For the location of the health LED, see Figure 5 on
page 11.)

The health LED indicates whether the MP access point is ready for operation.

● If the health LED is green and glowing steadily, the MP has been booted

successfully by the MX switch and is ready for operation.

● If the health LED is not steadily glowing green, contact the system

administrator for the MX switch or, if you are the system administrator, see
Appendix A, “MP Troubleshooting,” on page 53.
