16/24-Port 10/100Mbps Unmanaged Ethernet Switch With Priority Queue QoS 16 or 24 10/100Mbps Ethernet Ports Ideal for SOHO and Workgroup Deployment IEEE 802.1p QoS Support Solid Desk Metal Case FEATURES 16 or 24 10/100BASE-TX Ethernet Ports 16-Port Switch With 3.2Gbps Switch Capacity 24-Port Switch With 4.8Gbps Switch Capacity 802.1p QoS Support (2 Queues) Auto MDI/MDIX for Each Port Full/Half-Duplex Support for Each Port 802.3x Flow Control Per Port for Data Loss Protection Secure Store-and-Forward Switching Scheme Solid Desk Metal Case Brackets Provided for Mounting in Standard 19-Inch Equipment Rack The DES-1016D and DES-1024D are unmanaged 10/100Mbps Ethernet switches designed for cost-effective SOHO and workgroup connection. Equipped with 16 and 24 10/100Mbps ports in a solid metal desktop case, these switches provide low-cost connections for workstations on the twisted-pair network cables. 16/24 Plug-and-Play Desktop Connections. With 16 and 24 10/100BASE-TX ports supporting auto-sensing speeds and auto MDI/MDIX plug-and-play, these switches provide easy, low-cost connection for desktop computers. Flow Control for Secure Transmission. The switch provides 802.3x standard flow control to minimize dropped packets. It does this by sending out collision signals when the port's receiving buffer is full. This function support allows you to safely deploy servers operating at 200Mbps full duplex mode for simultaneous access from workstations with minimal risk of data loss. Quality of Service (QoS). The switches provide 802.1P priority queues for QoS, allowing users to run bandwidth-sensitive applications such as multi-media and VoIP Internet telephone without data flow bottlenecks that can degrade the quality of the network connection. 1 DES-1016D/DES-1024D Technical Specifications General Standards IEEE 802.3 10BASE-T Ethernet IEEE 802.3u 100BASE-TX Fast Ethernet ANSI/IEEE 802.3 NWay auto-negotiation IEEE 802.3x Flow Control IEEE 802.1p Number of Ports DES-1016D: 16 10/100BASE-TX ports with auto MDI/MDIX DES-1024D: 24 10/100BASE-TX ports with auto MDI/MDIX Full/Half Duplex Support Ethernet/Fast Ethernet: full/half duplex Flow Control Half duplex mode: back pressure Full duplex mode: 802.3x flow control LED Report Per device: Power Per port: Link/Act 10/100Mbps Speed Full Duplex/Collision (for DES-1016D only) Performance Switch Fabric DES-1016D: 3.2Gbps DES-1024D: 4.8Gbps Transmission Method Store-and-forward MAC Address Table DES-1016D: 8K entries per device DES-1024D: 8K entries per device MAC Address Learning Automatic update RAM Buffer DES-1016D: 160KBytes DES-1024D: 160KBytes Packet Filtering/Forwarding Rate 10BASE-T: 14,880 pps per port 100BASE-TX: 148,809 pps per port QoS IEEE 802.1p QoS support (2 queues) Physical & Environmental Power Input 100 to 240 VAC, 50/60 Hz Internal universal power supply Dimensions (W x D x H) 280 x 180 x 44 mm (11 x 7.09 x 1.73 inches) Operating Temperature 0O to 40OC(32 O to 104OF) Storage Temperature -10O to 70OC(14 O to 158OF) Operating Humidity 10% to 90% non-condensing Storage Humidity 5% to 90% non-condensing Emission (EMI) FCC Class A ICES-003 Class A CE Class A VCCI Class A C-Tick Class A MTBF DES-1016D: 47,220 hours DES-1024D: 32,274 hours Safety CUL Power consumption 6.8 Watts I C US D-Link Worldwide Offices U.S.A Canada Europe, UK & Ireland Germany France Netherlands Belgium & Luxemburg Switzerland Sweden Denmark Norway Finland Italy Spain Portugal Greece Czech Republic Hungary Poland TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: 1-800-326-1688 1-905-8295033 44-20-8955-9000 49-6196-77990 33 1 30 23 86 88 31-10-282-1445 32(0)2 517 7111 41 (0) 1 832 11 00 46-(0)8564-61900 45-43-969040 47 99 300 100 358-10 309 8840 39-02-2900-0676 34 93 409 0770 351 21 8688493 30 210 9914 512 420 224 247 500 36 (0) 1 461 30 00 48 (0) 22 583 92 7 FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: 1-866-743-4905 1-905-8295223 44-20-8955-9002 49-6196-7799300 33 1 30 23 86 89 31-10-282-1331 32(0)2 517 6500 41 (0) 1 832 11 01 46-(0)8564-61901 45-43-424347 47 22 30 95 80 358-10 309 8841 39-02-2900-1723 34 93 491 0795 Singapore Australia India Middle East (Dubai) Egypt Turkey Iran Pakistan Israel Latin America Brazil South Africa Russia Japan Korea China Taiwan Headquarters TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: TEL: 65-6774-6233 61-2-8899-1800 91-22-2652 6696 971-4-391-6480 202-291-9035 90-212-289-5659 90-212-289-5659 92-21-454-8158 972-9-9715700 56-2-5838-950 55-11-2185-9300 27-12-665-2165 7-495-744-0099 81-3-5781-0963 82-2-890-5491 86-10-58635800 886-2-6600-0123 886-2-6600-0123 FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: FAX: 65-6774-63225 61-2-8899-1868 91-22-2652 8914 971-4-390-8881 202-291-9051 90-212-289-7606 90-212-289-7606 92-21-453-5103 972-9-9715601 56-2-5838953 55-11-2185-9322 27-12-665-2186 7-495-744-0099 81-3-5781-0965 82-2-890-549 86-10-58635799 886-2-6600-3939 886-2-6600-9898 FAX: 30 210 9916902 FAX: 36 (0) 1 461 30 09 FAX: 48 (0) 22 583 92 76 2 Rev. 03 (Apr. 2007) DES-1016D/DES-1024D Specifications subject to change without prior notice.
