D-Link DXS-3250E - xStack Switch Specifications

provide aggregation for servers in data centers with an emphasis on security, performance, and resiliency. With a hot-swappable power supply and removable fan tray in a 2U case, the xStack DXS-3250E can be used to optimize switching performance in a rack server configuration. It provides 48 built-in copper Gigabit ports, including four combo SFP ports for easy, flexible connection to fiber-based Gigabit media. It is also equipped with one module slot that supports optional 10-Gigabit Ethernet for two XFP fiber connections. Load-Sharing Power Supply For Non-Stop Redundancy The xStack DXS-3250E supports two power supply trays for redundancy and continuous support. Each switch contains one internal power supply tray with one slot for an optional additional power supply tray, which can be installed for redundancy and load sharing. Both trays are located in the front of the switch for convenient access. In the event of a failure of one tray, power will immediately be supplied by the other tray without interrupting or affecting the system. The failed power supply tray can be removed and replaced by a new power supply tray without powering down the switch, thus maximizing the uptime of the network. The DXS-3250E also has a removable fan tray that can easily be accessed and replaced. Comprehensive Security The DXS-3250E handles many security vulnerabilities previously delegated to standalone firewalls. It supports Access Control Lists (ACLs) based on MAC address, switch port, IP address, and/or TCP/UDP port numbers. The DXS-3250E also features 802.1X Authentication, Guest VLAN, and RADIUS and TACACS+ for strict access control over the network. Additionally, port-based security can help to protect network integrity. Port numbers can be pre-programmed for specific applications, allowing these applications to provide faster service and reducing load on the CPU. Voice and Video Requirements The DXS-3250E provides a robust and consistent set of QoS/CoS, supporting eight priority queues for 802.1p/ToS/DiffServ, with classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP. The DXS-3250E also supports IEEE 802.3ad Link Aggregation for bandwidth management. Other traffic management features include: Layer 3 Static Routing, Bandwidth Control, Broadcast Storm Control, and Private VLAN Edge. For multicast traffic, IGMP Snooping v1/2/v3 and IGMP query are supported. Besides multicast forwarding, the DXS-3250E also supports Multicast TV. In today’s deployment of IPTV, this feature is crucial for bandwidth management. Multicast TV allows subscribers to join the same multicast stream, even if the subscribers are not members of the same VLAN, eliminating television traffic duplication. Network Management The DXS-3250E features a variety of network management options: Industry standard console CLI, Telnet, easy-to-use Web Graphic Interface, and SNMPv1/2c/3. Administrative access can be secured through SSH2/SSLv3. It also features 802.1w Rapid Spanning Tree to increase network reliability and availability. For larger networks, 802.1s Multiple Spanning Tree is supported to provide up to 15 instances per switch. To monitor traffic, the DXS-3250E supports RMON and port mirroring. It also allows dual firmware image and configurations to be stored to ease deployments. Furthermore, cable diagnostics is included to minimize deployment issues that may be associated with bad cables. xStack® Managed 48-Port Gigabit L2+ Switch, 2U Form Factor with 4 Combo SFP and 1 Slot for Optional 2-Port XFP Module DXS-3250E High Performance Switching + Optional Dual 10-Gig XFP Uplink Ports + Hot Swappable Power Supply + Up to 32 Static IP Routes + Virtual Cable Diagnostics + Removable Fan Module Advanced Enterprise Features + 802.1X (Port & MAC Authentication) + 4K VLANs + TACACS+ & RADIUS + RADIUS Accounting + QoS (8 Queues) + 802.1D/w/s Spanning Tree + SSH2/SSL + Private VLAN Edge + Guest VLANs + IGMPv1/2/3 + IGMP Querier + Multicast TV VLANs + Rate Limiting + SNMPv1/v2c/v3 + RMON + Rapid Spanning Tree 802.1w + Port Mirroring + Protocol-based VLANs + Multiple Spanning Tree 802.1s (Shown with optional DEM-412X 10-Gig Module)
