Perhaps, remove the module and verify if the AP is OK and then reinstall.
•
Module should show up as "slot-2".
•
If you suspect PoE (try AIR-PWRB or AIR-PWR-INJ4).
•
Module not designed to work with AIR-PWR-INJ5.
•
Some caveats regarding clients connecting to the module
802.11ac clients need same type of security as 802.11n to connect.
•
WPA/WPA2 with AES or Open.
–
CCKM is not supported in this release.
–
The module radio supports 50 clients in hardware.
•
• 8 keys for multicast traffic, one per SSID–8 keys for 8 SSIDs maximum on 11ac radio.
• 42 keys for the client unicast traffic.
• If more than 42 clients are associated, clients will be connected, but throughput for some clients will degrade because
encryption/decryption is done in software.
Features not supported in the module
MFP–Management Frame Protection
CCX–Cisco Compatible Extensions (Integrated 5 GHz radio handles these requests)
IAPP (used to connect WGBs and their clients)–no WGB support.
You can connect a WGB in WGBu (universal) mode, because it essentially behaves like a standard client,
Note
but no WGBC support. Also, not supported are SE-Connect, Mesh, and Monitor and Autonomous
modes.
Understanding 802.11ac and the AP 3700 (Wave-1)
The AP 3700 series is a dual band AP with integrated 802.11ac Wave-1 radio freeing up the feature module for more options
and flexibility. The AP 3700 contains the same industry leading architecture 4X4:3 found in the AP 3600. With additional
features and functionality such as ClientLink 3.0 as well as the option to use external antennas with 802.11ac applications, the
AP 3700 is indeed Cisco's best of breed AP.
The AP 3700 runs at 800 MHz w/512 MB of RAM running a purpose built Cisco Custom Application Specific Integrated
Circuit (ASIC). This custom chip incorporates Spectrum Intelligence, ClientLink 3.0 along with proprietary Cisco IP for data
plane hardware acceleration.
The AP 3700 is a robust AP with full metal shielding requiring no vent holes and is water resistant. This AP is suitable for
medical environments where cleaning chemicals may be used. Note that the feature module is also well shielded from the rest
of the AP with areas open on the sides for the feature module antennas to properly radiate. The AP 3700 is of course
upgradeable to the 802.11ac Wave-2 via option module.
Antennas on the AP 3700 radiate in much the same way as the AP 3600 patterns for both are in this guide
