AP-5131 Introduction
1-11
The Symbol Power Injector (Part No. AP-PSBIAS-T-1P-AF) is a single-port, 802.3af compliant Power
over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the
AP-5131. The Power Injector’s single DC and Ethernet data cable creates a modified Ethernet cabling
environment on the AP-5131’s LAN port eliminating the need for separate Ethernet and power cables.
For more information on the Symbol Power Injector, see Symbol Power Injector System on page 2-7.
1.1.14 MU-MU Transmission Disallow
The AP-5131’s MU-MU Disallow feature prohibits MUs from communicating with each other even if
they are on different WLANs, 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 AP-5131.
For information on configuring an AP-5131 WLAN to disallow MU to MU communications, see
Creating/Editing Individual WLANs on page 5-24.
1.1.15 Voice Prioritization
Each AP-5131 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 AP-5131 802.11a or 802.11b/g 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 AP-5131 to assign
priority to voice traffic over data traffic, and (if necessary) assign legacy voice supported devices (non
WMM supported voice devices) additional priority. For information on configuring voice prioritization
over other voice enabled devices, see Setting the WLAN Quality of Service (QoS) Policy on page 5-31.
