Power & Value\n The D-Link DGS-1250 Series Smart Managed Switches deliver real value as an Enterprise Access & Small-to-Medium Business (SMB) Access/ Aggregation solution. They provide a range of physical interfaces (including a Console Port w/full CLI), multiple management interfaces, 11 Web languages, Qo S enablement, & Advanced Layer-2 w/ Lite Layer-3 features.\n \n The DGS-1250 Series switches support 24 or 48 x 10/100/1000BASE-T ports, with each switch also supporting an additional 4 x 10G SFP+ ports for optical connections using multimode or single-mode SFP transceivers " enabling real network horsepower at a value price.\n \n Easy Maintenance, Less Downtime\n The DGS-1250 Series supports Dual Image & Dual Configuration functionality, as well as a Console Port, all of which make it easier to configure, troubleshoot, & make other changes without interfering with network operation, while full Command Line Interface (CLI) functionality enables remote configuration, without the need for the Internet. & if a network issue ever does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep things running without interruptions or downtime.\n \n Automatic Configuration\n The DGS-1250 Series supports Auto Voice VLAN & Surveillance Mode, which allow Voice & Video traffic to be automatically identified & handled differently from regular network traffic. Auto Voice VLAN detects Voice over IP (Vo IP) traffic & automatically segments it from the rest of the network, increasing security & allowing Quality of Service (Qo S) to be applied.\n \n Extensive Management & Advanced Features\n The DGS-1250 Series comes equipped with IGMP snooping, Port Mirroring, Spanning Tree Protocol (STP), & Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfers.\n \n The series also supports advanced features such as Static Routing, which allows for communication between different user groups in different VLAN segments in a network. &, because the switches can manage internal routing, the network router can be assigned to handle external traffic.\n \n Management Versatility\n The DGS-1250 Series comes with the D-Link Network Assistant (DNA) utility so admins can remotely control their network to the port level. DNA allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment & display them onscreen for instant access.\n\n class="generic"> Management features Multicast support Yes ARP inspection Yes Switch type Managed Web-based management Yes System event log Yes Quality of Service (Qo S) support Yes MIB support RFC2893, RFC4213, RFC4291, RFC2464, RFC2462, RFC4862, RFC2461, RFC4861, RFC2573, RFC1321, RFC2284, RFC2865, RFC2716, RFC3580, RFC826, RFC2463, RFC4443, RFC792, RFC793, RFC768, RFC791, RFC2389, RFC4113, RFC4022, RFC2618, RFC2674, RFC1398, RFC1643, RFC1650, RFC2358, RFC2665, RFC2021, RFC271, RFC1757, RFC2819, RFC1442, RFC1901, RFC1902, RFC1903, RFC1904, RFC1905, RFC1906, RFC1907, RFC1908, RFC2578, RFC3418, RFC2573, RFC2575, RFC2576, RFC1212, RFC1213, RFC1215, RFC1493, RFC1157, RFC2620, Switch layer L3 Configuring Location Settings (CLI) Yes Networking IGMP snooping Yes Networking standards IEEE 802.1D, IEEE 802.1Q, IEEE 802.1p, IEEE 802.1s, IEEE 802.1w, IEEE 802.3, IEEE 802.3ab, IEEE 802.3ad, IEEE 802.3ae, IEEE 802.3az, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z Head-of-line (HOL) blocking Yes VLAN support Yes Spanning tree protocol Yes Number of VLANs 4094 Link aggregation Yes Flow control support Yes Broadcast storm control Yes Auto MDI/MDI-XYes 10G support Yes Virtual LAN features Voice VLANVirtual LAN features VLAN support Yes Number of VLANs 4094 Virtual LAN features Voice VLANData transmission Number of VLANs 4094 Jumbo frames 12000 Number of static routes 124 Packet buffer memory 16 MBMAC address table 32000 entries Switching capacity 176 Gbit/s Jumbo frames support Yes Static route Yes Forwarding rate 130.95 Mpps Performance Packet buffer memory 16 MBNoise level 50.7 d B Memory type DDR3-SDRAMMean time between failures (MTBF)589984.72 h Internal memory 2048 MBFlash memory 64 MBTechnical details Product colour Black Noise level 50.7 d B Mean time between failures (MTBF)589984.72 h Shipping (inner) case width 47.8 cm Shipping (inner) case net weight 18.3kg Shipping (inner) case length 58.5 cm Shipping (inner) case height 38.4 cm Quantity per shipping (inner) case 5 pc (s) Shipping (inner) case gross weight 22.8kg Quantity per pallet (sea)80 pc (s) Quantity per pallet (air)80 pc (s) Pallet width 120 cm Pallet length 110 cm Pallet height (sea)167.1 cm Pallet height (air)167.1 cm Pallet gross weight (sea)382.7kg Pallet gross weight (air)382.7kg Number of cartons per pallet (sea)16 Number of cartons per pallet (air)16 Ports & interfaces SFP+ module slots quantity 4 Basic switching RJ-45 Ethernet ports quantity 48 Basic switching RJ-45 Ethernet ports type Gigabit Ethernet (10/100/1000) Console port RJ-45 Optical fiber Fiber ethernet cabling technology 100BASE-FX, 1000BASE-LHX, 1000BASE-X, 1000BASE'LX, 1000BASE'SX, 1000BASE'ZXSecurity Loop protection Yes IP-MAC-Port binding Yes Access Control List (ACL) rules 768 Security algorithms EAP, LEAP, MD5, PEAP, SSH, SSL/TLS, TTLSIGMP snooping Yes Access Control List (ACL) Yes Queue scheduling algorithms Weighted Round Robin (WRR)DHCP features DHCP client, DHCP server, DHCP snooping Multicast features Multicast support Yes Certificates Electromagnetic compatibility CE A, VCCI A, FCC A, IC, BSMICertification CB, UL, BSMI, CCCMemory Packet buffer memory 16 MBMemory type DDR3-SDRAMInternal memory 2048 MBFlash memory 64 MBDesign Product colour Black LED indicators Activity, Link, Power, Speed Electromagnetic compatibility CE A, VCCI A, FCC A, IC, BSMICertification CB, UL, BSMI, CCCIndication LED indicators Activity, Link, Power, Speed Power Power consumption (max)51.2 WPower supply included Yes AC input voltage 100
