Motorola Solutions AP-7131N-FGR Access Point Product Reference Guide
1-16
1.2.16 Power-over-Ethernet Support
When users purchase a Motorola Solutions WLAN solution, they often need to place access points
in obscure locations. In the past, a dedicated power source was required for each access point in
addition to the Ethernet infrastructure. This often required an electrical contractor to install power
drops at each access point location.
An approved Power Injector solution merges power and Ethernet into one cable, reducing the burden
of installation and allows optimal access point placement in respect to the intended radio coverage
area. The access point can only use a Power-over-Ethernet device when connected to the access
point’s LAN (GE1/POE) port. The access point can also support 3af/3at compliant products from other
vendors.
The Power Injector (Part No. AP-PSBIAS-1P3-AFR) is a single-port Power over Ethernet hub combining
low-voltage DC with Ethernet data in a single cable connecting to the access point. The Power
Injector’s single DC and Ethernet data cable creates a modified Ethernet cabling environment on the
access point’s LAN port eliminating the need for separate Ethernet and power cables. For detailed
information on using the Power Injector, see Power Injector System on page 2-6.
1.2.17 MU-MU Transmission Disallow
The access point’s MU-MU Disallow feature prohibits MUs from communicating with each other even
if on the same WLAN, assuming one of the WLAN’s is configured to disallow MU-MU
communication. Therefore, if an MU’s WLAN is configured for MU-MU disallow, it will not be able to
communicate with any other MUs connected to this access point.
For detailed information on configuring an WLAN to disallow MU to MU communications, see
Creating/Editing Individual WLANs on page 5-29.
1.2.18 Voice Prioritization
Each access point WLAN has the capability of having its QoS policy configured to prioritize the
network traffic requirements for associated MUs. A WLAN QoS page is available for each enabled
WLAN on either the 802.11a/n or 802.11b/g/n radio.
Use the QoS page to enable voice prioritization for devices to receive the transmission priority they
may not normally receive over other data traffic. Voice prioritization allows the access point to assign
priority to voice traffic over data traffic, and (if necessary) assign legacy voice supported devices (non
WMM supported voice devices) additional priority.
