Cost-effective solution for the small and medium business
The DES-1228P Web Smart Switch from D-Link is a cost-effective solution for the small and medium business that requires basic management features like VLAN segmentation, QoS prioritization, and secure 802.1x login and authentication, showcased in a low-cost, easy-to-configure, and GUI managed smart business solution. The DES-1228P comes with 24 10/100BASE-TX Fast Ethernet ports, 4 1000Base-T ports and 2 combo ports for flexible copper/fiber Gigabit connections to storage area network devices, servers, or core switching solutions. It supports 24 ports of PoE up to 15.4 watts to power PD devices such as APs, phones, and cameras. The Graphical User Interface allows you to implement Quality of Service (QoS), VLANs and security without having to go through complex command line management usually found in other managed switches. Features and Benefits: D-Link Safeguard Engine: The DES-1228P incorporates advanced mechanisms to detect an attack against the central processing unit of the switch and to take corrective action on the attacking interface. When a Denial of Service (DoS) attack is waged against the DES1228P, the D-Link Safeguard Engine detects the threat and prevents overload of the central processor thus insuring network integrity and helping to maintain open network bandwidth channels. IEEE 802.3af PoE: The DES-1228P features 24 10/100BASE-TX ports that support IEEE 802.3af PoE protocol. Each of the 24 PoE ports can supply up to 15.4 Watts, a total PoEbudget of 170 Watts, allowing users to attach any IEEE 802.3af compliant device to the DES-1228P without needing additional power. This eliminates the need of having to place networking devices within close proximity of a power outlet and minimizes cable clutter in awkward places such as ceilings or walls. For devices that are not IEEE 802.3af compliant, a PoE adapter, such as D-Links DWL-P50 can be used to enable the non-compliant device to receive power through theDES-1228P. Port Trunking: The DES-1228P supports static port trunking of up to 6 groups of 8 ports per device. Ports can be combined together to create multi-link loadsharing aggregated trunks to a server or a network backbone. To expand the network, you can also make use of link aggregation to eliminate bottlenecks between the cascaded switches.
FEATURES AND BENEFITS
802.1Q VLANs: The DES-1228P provides support for 802.1Q VLANs for improved security and bandwidth utilization. VLANs work by segmenting broadcast domains thus reducing network congestion due to constant network broadcasting. In addition VLANs provide a means of securing each broadcast domain from all others. This in turn prevents users on one VLAN from gaining access to resources on other network segments. VLANs can be configured to segment departmental resources. For example, VLANs can be implemented on an SMB network to prevent the Marketing department from gaining access to secure resources in the Accounting department. SNMP Management: The DES-1228P supports SNMP v1. SNMP is a useful tool in managing and controlling SNMP supported network devices. SNMP enables the DES-1228P to be polled to provide valuable information about the status of the unit and send traps on abnormal events. This sharing of vital management information saves time and money. 802.1p Priority Tagging: Like 802.1Q VLAN tagging, 802.1p places a tag in a frame to indicate the priority of the frame. A tag will represent a priority of 0-7 and an 802.1Q compliant switch can read this tag and prioritize traffic accordingly. This differs from port based QoS in that in Port-Based QoS all traffic entering a specific port is prioritized the same way with the same value. In 802.1P a port can receive frames with varying priority tags and classify them based on these tags. A VoIP phone that supports 802.1P can assign a priority to its VoIP traffic and when it enters the switch the switch can give it a higher priority so that voice traffic is always clear and jitter-free. 802.1D Spanning Tree: Spanning Tree provides protection from unintentional cabling loops forming within a network infrastructure. Loops are dangerous in that they create an unending circle where broadcast and multicast traffic propagate across the network in an endless loop. This creates a storm of traffic that overwhelms the network and brings traffic to a crawl. 802.1D Spanning tree detects and breaks these loops ensuring network uptime. IGMP Snooping:
IGMP Snooping allows for the forwarding of multicast packets such as streaming audio, video, without increasing network broadcast congestion. By snooping IGMP registration information within a frame, a list of workstations who have joined the multicast group is created. This list then allows the switch to intelligently forward packets to only the appropriate member workstations. 802.1x Authentication: 802.1x Authentication provides a secure means to allow users to log onto your network. When used in conjunction with a RADIUS server, 802.1x requires each user workstation attached to the DES-1228P to provide a username and password before gaining access to the local area network. Operational Simplicity: The DES-1228P supports a wide array of plug-inplay features: 10/100Mbps auto-negotiation Universal UTP cable recognition for auto straightthrough or crossover cable detection Full/Half duplex support IEEE standards support Managing the DES-1228P has never been easier. Using its built in browser-based management interface, configuring the switch takes only minutes. With full color graphic pictures, diagrams and easy to understand navigation menus, configuring the DES1228P with the features you require is as easy as surfing the net. The DES-1228P supports many of todays most sought after features like 802.1P priority queuing, 802.1Q VLANs, port trunking, 802.1x authentication, port mirroring, SNMP, spanning tree, link aggregation, IGMP Snooping, broadcast storm control, and more.

Web Smart PoE Thin Access Point, 802.3af, 802.11g
Flexible Wireless LAN Connectivity
The small form factor DWL-3140AP provides secure client access that supports the new wireless functionality of the DES-1228P Web Smart Switch. Installation of multiple DWL-3140APs increases client mobility within a network. Each DWL-3140AP continually tunes itself for optimal RF channel and transmit power to provide all mobile clients with the best wireless signal.
Continuous Channel Scanning To Prevent Rogue APs2
DWL-3140APs play a key role in rogue detection they continuously scan their associated wireless channels to root out rogues while simultaneously providing wireless connectivity to mobile clients. If a rogue AP is detected, the closest DWL-3140AP can launch RF countermeasures by spoofing 802.11 control messages. This prevents clients from communicating, associating, and authenticating with a rogue AP.
High Performance Connectivity
+ IEEE 802.11g Wireless + Up to 108Mbps1 + Self-Tuning Features to Adjust and Optimize RF Settings + Multiple SSID2 + WLAN Partition2
Sensitive Information Not Stored Locally
Individual DWL-3140APs do not store data locally so they can be safely installed in unsecured areas without fear of hacking or theft. The DES-1228P Web Smart Switch is the hardware that stores vital network and user information and is typically stored in a secure location. DWL-3140APs can link to DES-1228Ps directly or through the existing wired network - even across Layer 3 boundaries2 and receive Power-over-Ethernet (PoE) from directly connected DES-1228Ps or third-party PoE injectors.
Increases User Productivity
For important wireless transmissions such as VoIP related applications, DWL-3140APs also deliver critical user-based services, such as prioritized delivery of voice traffic. Supporting multiple queues per user, DWL-3140APs always prioritize expedited traffic such as voice calls, before servicing three other levels of traffic in priority order.
Trusted Security Features
+ 64/128/152-bit WEP + WPA + WPA-PSK + WPA2 + WPA2-PSK + Rogue AP Detection2
Thin Client AP
+ Minimizes Risk by Not Storing Data Locally
Self-Configuration and Easy Installation
The DES-1228P Web Smart Switch automatically configures every connected DWL-3140AP so that no configuration is necessary during installation. If a DWL-3140AP needs to be replaced, the replacement DWL-3140AP automatically inherits the same configuration, making the replacement process analogous to changing a light bulb. These DWL-3140APs intentionally resemble smoke detectors to minimize visibility. With no protruding antennas and no obvious hallmarks of an AP, DWL-3140APs are less likely to be tampered with.
