The AP-4000, AP-4000M, and AP-4900M are tri-mode APs that simultaneously support 802.11b, 802.11g, or 802.11a 
clients.

The AP-4000/4000M/4900M contains two embedded radios: one 802.11b/g radio and one 802.11a only radio. The 
802.11a radio supports operation in 802.11a only mode in the AP-4000, and operation in either 802.11a only or 4.9 GHz 
Public Safety mode in the AP-4900M. 4.9 GHz Public Safety mode is for use in the licensed 4.9 GHz band; only users 
with licenses to operate in this band should access it. 

The 802.11b/g radio supports the following operational modes:

• 802.11b only mode
• 802.11g only mode

The AP-4000/4000M/4900M can be powered through either Active Ethernet (802.3af Power over Ethernet) or through 
an external DC power source using the power cord.
