Cisco Systems AIRRM3000ACAK9 manual Things to look for if the module is not found

Understanding 802.11ac and the option module

•Not understanding SSID’s for both 5 GHz need to be the same and all .11ac clients are sent to the

.11ac module

Figure 74 Both thumbscrews need to be tight or power is not applied

Things to look for if the module is not found

•Console will report “module radio found and ok”

•Also console CDP message for Power “Power ok – HIGH POWER inline power source”

•Perhaps remove module – verify AP ok 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 on this release

•The module radio supports 50 clients in hardware

•8 keys for multicast traffic one per SSID – 8 keys for 8 SSIDs max 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 since 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. Note: You can connect a WGB in WGBu (universal) mode, because it essentially behaves like a standard client, but no WGBC support. Also not supported are SE-Connect, Mesh, Monitor and Autonomous modes
