D-Link DAP-2590 PoE Access Point Description:

D-Link, an industry pioneer in wireless networking, introduces a solution for businesses seeking to deploy next generation 802.11n LANs. D-Link unveils its new AirPremier N Dual Band PoE Access Point (DAP-2590), designed specifically for business-class environments such as large or enterprise corporations to provide secure and manageable dual band wireless LAN options for network administrators.


Versatile Access Point

The DAP-2590 allows network administrators to deploy a highly manageable and extremely robust dual band wireless network. All three dual band antennas are detachable and can provide optimal wireless coverage in either 2.4GHz (802.11g and 802.11n) or 5GHz (802.11a and 802.11n) bands. Enclosed in a plenum-rated metal chassis, the DAP-2590 adheres to strict fire codes for placement in air passageways. For advanced installations, this new high-speed Access Point has integrated 802.3af Power over Ethernet (PoE) support, allowing installation of this device in areas where power outlets are not readily available.

Enhanced Performance

The DAP-2590 delivers reliable wireless performance with maximum wireless signal rates of up to 300Mbps** in either the 2.4GHz or 5GHz wireless band. This, coupled with support for Wi-Fi Multimedia™ (WMM) Quality of Service features, makes it an ideal access point for audio, video, and voice applications. Additionally, the DAP-2590 supports load balancing features to ensure maximum performance by limiting the maximum number of users per Access Point.

Multiple Operation Modes

To maximize total return on investment, the DAP-2590 can be configured to optimize network performance based on any one of its multiple operation modes: Access Point, Wireless Distribution System (WDS) with Access Point, WDS/Bridge (No AP Broadcasting) and Wireless Client. With WDS support, network administrators can set up multiple DAP-2590s throughout a facility and configure them to bridge with one another while also providing network access to individual clients. Also included are advanced features such as Load Balancing, which optimizes high network traffic volume, and redundancy for fail-safe wireless connectivity. Additionally, the DAP-2590 offers Spanning Tree Protocol support for greater efficiency and to avoid broadcast storms when used in WDS mode.

D-Link Smart-III series is the latest generation of Web Smart switches. D-Link Smart III series offers a complete suite of features, including simple management, advanced security and QoS features. The pre-set default configuration allows plug-and-play, this eases the effort of setting up the switch. D-Links Smart III switching family (DES-1210&DGS-1210) offers a solution that comes with key managed switch features without the hefty price tag.

D-Link Brings its Web Smart Switch DES-1210

The D-Link® Web Smart switch has six types: DES Series DES-1210-28,DES-1210-28p and DES-1210-52,DGS Series DGS-1210-28,DGS-1210-28p and DGS-1210-52. 28p has POE Features. DES Series has 10/100M Port and 2 10/100M/1000M port,DGS Series

Seamless Integration

The Web Smart switch DES-1210 is designed to provide SMB users complete control over the network. With Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables, this switch eliminates the need for a complex reconfiguration process. The DES-1210 allows for a flexible connection to a backbone or servers. Additionally, all ports support auto-negotiation of MDI/MDI-X crossover, or configurable auto MDI, and therefore do away with crossover cables or uplink ports. This brings inexpensive and easy connectivity to your desktop.

QoS, Bandwidth Control

The switch is perfect for deployment in a VoIP environment, as it supports Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service.

Secure Your Network

The innovative D-Link Safeguard Engine function protects the switch against traffic flooding caused by virus attacks. The DES-1210-28 switch supports 802.1X port-based authentication, allowing the network to be authenticated through external RADIUS servers. In addition, the Access Control List (ACL) feature enhances network security and helps to protect the internal IT network by allowing an administrator to restrict the access of a network through a variety of means including MAC address, IP, UDP/TCP, and even VLAN ID.

With wide variety of manageability functions such as an intuitive SmartConsle Utility, easy-to-use Web browser, SNMP-based management, compact command lines, and integration with D-Link D-View 6.0. Thus Smart III Series makes it easy for small-and mid-sized organization to implement and manage the switch and networks. Flexible uplink ports design helps for SMBs to deploy network connection between switches and servers or core network backbones.

1.What D-Link products support the 802.3af(POE) protocol?

802.3af, also known as Power over Ethernet(POE), defines the standard for building Ethernet power-sourcing equipment and powered terminals.

The following D-Link products support the 802.3af protocol:

DWL-2700AP revA3

2.Does the D-Link PoE switch or adapter support PoE device?

When using a D-Link PoE adapter or Switch please ensure the device you are using is compliant with IEEE 802.3af standard.

D-Link can not support any device used with a PoE switch or adapter that is not 802.3af compliant, using the switch or adapter with a device that is not 802.3af compliant may cause damange to your device and it is strongly reccommended that you disconnect the device and discontinue use of your PoE device with the D-Link PoE adapter or switch.

3.Why does TeraTerm SSH lock up my DES-3828/DES-3828P?

This only happens when using an older version of TeraTerm.

Please ensure that your computer is running TeraTerm SSH version 3.1.3 or higher.

You can download a free copy of TeraTerm SSH at
