DWL-8220AP User's Manual
The DWL-8220AP access point (AP) provides IEEE 802.11 wireless access to the network.
It is designed for use with the D-Link DWS-1008 wireless switch. The access point requires
hardware installation only. All configuration for the access point takes place on the switch.
The DWL-8220AP has one 802.11a radio and one 802.11b/g radio. Both radios have
internal diversity omnidirectional antennas. In addition, both radios have separate jacks for
attachment of optional external sectorized or directional antennas. The antennas must be
ordered separately.
Note: Installation must be performed by qualified service personnel only. Read and follow all
warning notices and instructions marked on the product or included in the documentation.
The access point radios are disabled by default and can be enabled only by a system
administrator using the DWS-1008 wireless switch.
The DWL-8220AP has two RJ-45 ports. Each port provides a 10/100BASE-TX Ethernet
connection to a DWS-1008 switch. The connection can be direct to a DWS-1008 switch or
indirect through an intermediate Layer 2 or Layer 3 network.
The access point receives power and data through the RJ-45 ports. Use a straight-through
Category 5 (CAT5) Ethernet cable to connect an AP to a DWS-1008 switch or other device
in the network. The DWL-8220AP supports 802.3af, and also can receive PoE from D-Link
switches and D-Link-approved power injectors.
The two RJ-45 ports support dual-homed configurations for redundancy. The DWL-8220AP
uses only one link for booting, configuration, and data transfer. If the link becomes unavailable,
the AP can reboot using the other link. The ports are identical except for logical numbering (1
or 2).You can use either port to connect an AP access point to a DWS-1008 switch. However,
an AP always attempts to boot on port 1 first. Only if the boot attempt on port 1 fails does the
AP attempt to boot on port 2. If one port becomes unavailable, the other port can provide full
power to the AP.
Note: Access points do not support daisy-chain configurations. Do not connect the access
point to another access point.
