Release Notes for Cisco Aironet Access Points for Cisco IOS Release 12.3(8)JEC1
OL-16115-01
New Features
Operating 5-GHz Radio Requires Power Injector, Power Module, or Catalyst 3550-24 PWR Switch
The 1200 series power injector and the 1200 series power module support operation of the 5-GHz radio
in the access point. The Catalyst 3550-24 PWR switch supports power for both the 2.4-GHz radio and
the 5-GHz radio. Other switches and power patch panels might not provide enough power for the 5-GHz
radio.

radio.
Access Point Requires 1200 Series Universal Power Supply and Power Injector
If you use a power injector or a power module to provide power to a 1200 series access point, you must
use a 1200 series universal power supply. If you need to use a power injector to inject power into the
access point’s Ethernet port, you must use a 1200 series power injector.

Unpowered 1100 Series Access Points Cause Loopback When Connected to Switches Without
Loopback Detection
Loopback Detection
When you connect an unpowered 1100 series access point to a switch without loopback detection, the
access point causes a loopback. To avoid this problem, make sure loopback detection is enabled on the
switch to which the access point is connected. If your switch does not have loopback detection,
disconnect the access point from the switch when the access point power is off.

Antenna Installation
For instructions on the proper installation and grounding of external antennas for 1200 series access
points, refer to the National Fire Protection Association’s NFPA 70, National Electrical Code, Article
810, and the Canadian Standards Association’s Canadian Electrical Code, Section 54.

Warning
Do not install the antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, as they may cause serious injury or death.

System log messages
System Log Messages
With this release, the IOS command logging facility is available that allows users to customize the
severity level of system error messages by determining the severity levels of system error messages that
are reported or discarded. The command is supported on 1100, 1130, 1200, 1240, 1250, and 1300 series
access points and 1400 series bridges. The events covered by this command are:
