New Features
Step 17
To verify that the Cisco Unified Wireless Network Controller Boot Software 4.2.112.0 ER.aes file is
installed on your controller, enter the show sysinfo command on the controller CLI and look at the
Bootloader Version field. “N/A” appears if the ER.aes file is installed successfully. “Error” appears if
the ER.aes file is not installed.

Bootloader Version field. “N/A” appears if the ER.aes file is installed successfully. “Error” appears if
the ER.aes file is not installed.
Note
You can use this command to verify the boot software version on all controllers except the 2106
because the bootloader is not upgradable on the 2106 controller.

New Features
The following new features are available in controller software release 4.2.112.0.
1250 Access Point PoE Enhancements
The dual-radio 1250 series access point can operate in four different modes when powered using Power
over Ethernet (PoE):
over Ethernet (PoE):
•
20.0 W (Full Power)—This mode is equivalent to using a power injector or an AC/DC adapter.
•
16.8 W—Both transmitters are used but at reduced power. Legacy data rates are not affected, but the
M0 to M15 data rates are reduced. Throughput should be minimally impacted because all data rates
are still enabled. The range is affected because of the lower transmit power. All receivers remain
enabled.

are still enabled. The range is affected because of the lower transmit power. All receivers remain
enabled.
•
15.4 W—Only a single transmitter is enabled. Legacy data rates and M0 to M7 rates are minimally
affected. M8 to M15 rates are disabled because they require both transmitters. Throughput is better
than the legacy rate but less than the 20 and 16.8 W power modes.

•
11.0 W (Low Power)—The access point runs, but both radios are disabled.

PoE.
The following changes have been made for 1250 series access points running at reduced power on older
switches. These changes allow the access points to send a notification of the reduced power mode that
is in effect (CSCsm08712).

The controller raises a trap if the access point is not operating at full power. If lower power is used,
the trap contains “PoE Status: degraded operation.”

The controller shows whether the access point is operating at lower power:
–
On the controller GUI, click Wireless > Access Points > All APs > access point name >
Advanced tab. The PoE Status field shows one of the following: High (20 W), Medium (16.8
W), or Medium (15.4 W).
