Cisco Catalyst 9120AX Series Access Points
•Dual 5 GHz Mode—Serving clients on both 5 GHz Radios
•Wireless Security Monitoring—Scanning both 2.4 GHz and 5 GHz for security threats while also serving 5 GHz clients
What is a Smart Antenna connector?
The 9120AXE and 9120AXP models have a Smart antenna connector (see Figure 10), which is connected directly to the
flexible radio. Without a supported external antenna connected to the Smart Antenna connector, the flexible radio can
stay only in 2.4 GHz mode. If an external antenna is connected, the flexible radio can be used in the full Flexible Radio
Assignment mode, allowing dual 5 GHz and Wireless Security Monitoring modes.
To connect to any supported RP-TNC connector-type external antenna to the Smart antenna connector, use the DART
cable connector AIR-CAB002-DART-R= (see Figure 10), which is to be procured separately from Cisco.

What is Cisco Multigigabit Ethernet?
Cisco Multigigabit Ethernet (mGig) is a unique Cisco innovation also available in the Cisco Catalyst 9120AX series access
point. With the increasing popularity of 802.11ax and new wireless applications, wireless devices now require more
network bandwidth. Hence, there is a need for a technology that supports speeds higher than 1 Gbps on all cabling
infrastructure. Cisco Multigigabit technology allows you to achieve bandwidth speeds from 1 to 10 Gbps over traditional
Cat 5e cabling or newer. The 9120AX AP supports up to 2.5 Gbps using mGig.
