2.3.1 AP 300 Access Port Radio Characteristics
The Symbol Branch Office Wireless Switch Solution is an IEEE 802.11-compliant device containing
two 802.11 radios: an 802.11g radio operating in the 2.4 to 2.5 GHz band and an 802.11a radio
operating in the 4.9 to 5.875 GHz band. The following table lists radio characteristics for each radio's
compliance. The three supported 802.11g modes are simultaneous CCK and ODFM, CCK only, or
ODFM only.
Device Mbps Data Rate Support
802.11a 6, 9, 12, 18, 24, 36, 48, 54
802.11g 1, 2, 5.5, 11 CCK
6, 9, 12, 18, 24, 36, 48, 54 ODFM
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.

2.3.2 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
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.

802.11b/g Activity LED Green
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.
