Troubleshooting Radio Port Installation
Startup Error Checklist
Startup errors occur when the Radio Port is unable to communicate with a
compatible wireless services-enable switch, or when the Radio Port success-
fully communicates to a compatible switch but the switch is not able to adopt
and manage the Radio Port. The following steps can be used to determine the
different circumstances that may be preventing the Radio Port from being
adopted by the switch and operating normally.
1.
The network connection between the Radio Port and the wireless ser-
vices-enabled switch has been disrupted. Verify that network connectivity
between the Ethernet cable and the wireless services-enabled switch by
connecting another device, such as a laptop, to the Ethernet cable and
confirming network connectivity to the switch. Verify that the Ethernet
port to which the Radio Port is connected has not been disabled, and if
802.1x port security is turned on, that the 802.1x Port security is compat-
ible with the Radio Port's 802.1x settings.
2.
The network between the Radio Port and the wireless services-enabled
switch has a Layer 3compatibility issue (e.g. the two devices are on
different subnets.)

Diagnostic Tips
Off steadily while Ethernet cable is
linked to a PoE source. Remains off
even when Radio Port is disconnected
from Ethernet cable and reconnected.

Radio Port is not receiving PoE power. Verify that the Ethernet
cable is connected directly to an IEEE 802.3af-compatible PoE
source, and that all cable connections are tight and secure.
Verify that the PoE source device is powered on, and that the
PoE function has been administratively enabled on the source
port connected to the Radio Port. Verify that the network cable
is functioning properly, or try a different cable. Try plugging
the Radio Port into another PoE power source, or connect
another PoE device to the port to confirm if the PoE source is
functioning appropriately.
Both GREEN and AMBER LED Indicators light steadily for several seconds,
followed by the AMBER LED flashing steadily on and off three times a second for
several seconds, then this cycle repeats itself continuously.
The Radio Port is encountering a Startup Error, and is unable to
successfully communicate with or be adopted by a compatible
wireless services-enabled switch. See the Startup Error
checklist below for further diagnostic tips.
Flashes on and off steadily once per
second
*
The Radio Port has encountered an error that prevents the
802.11b/g radio from operating normally.
*
Flashes on and off steadily once per
second
(Radio Port 230 only) The Radio Port has encountered an error
that prevents the 802.11a radio from operating normally.
