Power-Over-Ethernet Support - Symbol AP-51xx Product Reference Manual

is defined by a set of managed objects called object identifiers (OIDs). An object identifier (OID) is
used to uniquely identify each object variable of a MIB.
SNMP allows a network administrator to configure the access point, manage network performance,
find and solve network problems, and plan for network growth. The access point supports SNMP
management functions for gathering information from its network components. The access point
downloads site contains the following 2 MIB files:
• Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
• Symbol-AP-5131-MIB (both the AP-5131 and AP-5181 use the same MIB, there is no specific
MIB for an AP-5181)
The access point SNMP agent functions as a command responder and is a multilingual agent
responding to SNMPv1, v2c and v3 managers (command generators). The factory default
configuration maintains SNMPv1/2c support of the community names, hence providing backward
compatibility.

1.2.13 Power-over-Ethernet Support

When users purchase a Symbol 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. An AP-5131 or AP-5181 can only use a Power-over-Ethernet device when connected to the LAN
port.
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
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 Symbol Power Injector, see
Injector and Power Tap Systems on page
The Symbol Power Tap (Part No. AP-PSBIAS-5181-01R) is also a single-port, 802.3af compliant Power
over Ethernet hub combining low-voltage DC with Ethernet data in a single cable connecting to the
access point. However, the Power Tap is designed and ruggedized for use with an AP-5181's outdoor
