1.1.11 Updatable Firmware
Symbol periodically releases updated versions of the AP-5131 device firmware to the Symbol Web
site. If the AP-5131 firmware version displayed on the System Settings page (see Configuring System
Settings on page 4-2) is older than the version on the Web site, Symbol recommends updating the
AP-5131 to the latest firmware version for full feature functionality. For instructions on updating the
AP-5131 firmware using FTP or TFTP, see Updating Device Firmware on page 4-34.
1.1.12 Programmable SNMP v1/v2/v3 Trap Support
Simple Network Management Protocol (SNMP) facilitates the exchange of management information
between network devices. SNMP uses Management Information Bases (MIBs) to manage the device
configuration and monitor Internet devices in remote locations. MIB information accessed via SNMP
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 AP-5131, manage network performance, find
and solve network problems, and plan for network growth. The AP-5131 supports SNMP management
functions for gathering information from its network components. The AP-5131 CDROM and the (AP-
5131 downloads site) contains the following 2 MIB files:
• Symbol-CC-WS2000-MIB-2.0 (standard Symbol MIB file)
• Symbol-AP-5131-MIB (AP-5131 specific MIB file)
The AP-5131 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. For
information on configuring SNMP traps, see Configuring SNMP Settings on page 4-11.
1.1.13 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 AP-5131 placement in respect to the
intended radio coverage area. The AP-5131 can only use a Power-over-Ethernet device when
connected to the LAN port.
