Release Notes for Cisco Wireless LAN Controllers and Mesh Access Points for Release 4.1.192.35M
OL-31336-01
Important Notes
Battery Charge Information is not Available for AP1510s with Power Supply 1.01d Firmware
An AP1510 with an Alpha FlexNet MPS30-48C-SL power supply must have firmware version 1.02d or
greater to supply information about its remaining charge to the controller and Cisco WCS. Otherwise,
the controller and WCS display incorrect battery information.

the controller and WCS display incorrect battery information.
To upgrade your power supply to 1.02d (or greater) firmware, return the power supply to an Alpha
service center (Argus).

Probing of Battery Charge Levels for 1510 Requires Allowance for Cycles
After detaching and reattaching a probe to a backup battery on a 1510 mesh access point, the battery
status remains at a 0% charge reading for up to 30 minutes. This is in keeping with the design of the
battery. The battery estimates its charge on 30 minute cycles (CSCsi83272).

Monitoring Port LED Status on an Cisco Aironet 1520 Series Access Point
When physically disconnecting a cable from an 1520 series access point, the port LED associated with
that connection might remain lit for up to 3 seconds.

Data Rate Considerations in Short Link Deployments of 1520s
For DFS bands, the Hammer 5-GHz radio does not meet the receiver saturation specification of -30 dBm
for some of the higher data rate modes due to a transceiver chipset optimization made to lower the DFS
false detect probability. The typical receiver saturation input level is -37 dBm at 24 and 36 Mb/s. Future
releases of the 1522 will contain an improvement to this parameter by way of further chipset register
setting optimization. The receiver saturation performance impact can be mitigated by reducing transmit
power and antenna gain where possible. For typical deployments where radios are separated by
reasonable distances there is no impact to high data rate support.

Warning Message Added for AP Bridging Disable Requests
When a request is made to disable access point bridging using either the controller GUI (All APs >
AP_Name > Mesh) or CLI (config ap bridging disable), the following message is displayed
(CSCsi88127,CSCsm16458):
AP_Name > Mesh) or CLI (config ap bridging disable), the following message is displayed
(CSCsi88127,CSCsm16458):
Disabling ethernet bridging will affect servicing of ethernet bridged clients.
Are you sure you want to continue?
Warning Message Added When Changing Antenna Gain
The following warning message appears when a change to the antenna gain is made on either the 1522
or 1524 radio. This message appears for both the controller CLI (config 802.11a antenna extAntGain)
and GUI (Wireless > Access Points > Radios). (CSCsl75327)

and GUI (Wireless > Access Points > Radios). (CSCsl75327)
Changing antenna gain can make current channel unusable. The AP will be rebooted. A new channel
must be chosen once the AP rejoins. If no channel is available with the new antenna gain, it will return
back to the original value. Are you sure you want to continue?
