Description

The AP 300 Access Port is an IEEE 802.11-compliant device containing one 802.11a radio and
one 802.11b/g radio. The unit contains internal 2.4-2.5GHz and 4.9-5.285GHz antennas and
supports UNII band 1, and it requires power from any UL-listed, 802.3af-compatible Power Over
Ethernet (PoE) power source.

Features

• One RJ-45 connector

• LED indicators

• Safety wire tie point

• Kensington-compatible lock port

• Slots for wall mounting

• Clips for mounting on a suspended ceiling T-bar

The AP 300 Access Port has one RJ-45 connector supporting an 10/100 Ethernet port and
requires 802.3af-compliant power from an external source.

The AP 300 Access Port comprises two 802.11 radios: an 802.11b/g radio operating in
the 2.4 to 2.5Ghz band and an 802.11a radio operating in the 4.9 to 5.875Ghz band. Each radio
has an embedded controller which runs local firmware used to perform the functions of the
lower 802.11 MAC. All upper MAC functions and MAC management are controlled by the
Wireless Switch.

Motherboard firmware enables the unit to boot after either a power up or a watchdog reset.
After self-boot, the motherboard sends an “I am alive” message into the network to be adopted
and loaded with the actual runtime code. The boot firmware on the motherboard and the

firmware downloaded from the switch can be updated via the Ethernet interface from the
Wireless Switch.

Lock Port

The lock port, compatible with Kensington-style security cables, is on the side of the case.

LED Indicators

The unit has LED activity indicators on the front of the case provide a status display indicating
error conditions, transmission, and network activity for the 802.11a (amber) radio or the

802.11b/g (green) radio.

Task 802.11a Activity LED Amber 802.11b/g Activity LED Green

Booting The amber LED flashes three times per second

until firmware is loaded. During boot, 802.11a
mobiles cannot associate.

Normal After adoption, the amber LED is steady or

flashes with 802.11a radio traffic.

Error The amber LED flashes once per second

if an error prevents the 802.11a radio from
operating normally.

The green LED flashes three times per second
until firmware is loaded. During boot,

802.11b/g mobiles cannot associate.
After adoption, the green LED is steady or

flashes with 802.11b/g radio traffic.
The green LED flashes once per second

if an error prevents the 802.11b/g radio from
operating normally.

Installation Instructions

The AP 300 Access Port mounts either on a wall with wide-shoulder screws or on a suspended
ceiling T-bar. This unit is not designed for mounting on a desk.

To prepare for installation, perform the following steps:

1. Match the model number on the purchase order with the model numbers in the packing
list and on the case of the device shipped.

2. Verify that the contents of the box include the intended AP 300 Access Port and
mounting hardware:

Item Notes

WSAP-5110-100-WW 802.11a/b/g configuration.

3. Review site survey and network analysis reports to determine the location and
mounting position for the AP 300 Access Port.

4. Connect a CAT-5 cable to a compatible 802.3af power source and run the cable to the
installation site. Ensure that there is sufficient slack on the cable to perform the
installation steps.

Wall Mount

This mounting requires hanging the AP 300 Access Port along its width or length using the two
slots on the bottom of the unit. The AP 300 can be mounted onto any plaster, wood, or cement
wall surface using the provided wall anchors when necessary. The illustration shows a
lengthwise mount.

Mounting Hardware: Two wide-shoulder Phillips pan head self-tapping
screws.

(7) (9) (11) (13)

9. Verify the unit has power by observing that the LEDs are lit or flashing.

Suspended Ceiling T-Bar Mount

Ceiling mount requires holding the AP 300 Access Port up a gainst a T-bar of a suspended ceiling
grid and twisting the case onto the T-bar.

Ceiling Mount Hardware
