SI 24-Port Top-of-Rack Managed Switch
D-Link Logo
24-Port 10 Gigabit SFP+ Layer 2+ Stackable Managed Switch (Standard Image) with Expansion Slot

24-Port Layer 3 Stackable 10G Fiber Managed Switch

Compact, high-performance switch for very low latency wire speed 10G fiber switching and routing

D-Link’s DXS-3600 10GbE L2/L3 Switch family consist of new compact, high-peformance switches that feature wired-speed 10-Gigabit Ethernet switching, routing, and very low latency. The 1U height and selectable front-to-back or back-to-front air flow make the DXS-3600 series suitable for top-of-rack (ToR) deployment in data centers or enterprise and campus aggregation network environments. The DXS-3600 switches have 24 fixed 10 GbE SFP+ ports and can feature more ports with the addition of an expansion module. The expansion modules not only provide extra 10G SFP+ ports, but also increase the flexibility of 120G stacking, 40G uplinks or low cost inter-rack 10G Base-T connections for different applications. The DXS-3600 switches deliver high-performance 10-Gigabit Ethernet switching capacity of up to 960 Gbps and forwarding rates of up to 595.2 Mpps. The switches feature hot-swappable power supplies and fan trays, which enable the switches to be a redundant, high availability architecture. The modular power design allows users to select AC or DC power according to where the switch is deployed. When inserting two power modules, the two power modules share the loading and help to extend the lifetime of the other. The DXS-3600 series also features a modular fan design. Three fans can back up each other, providing N+1 redundancy for the system. If one of the fans fails, the other fans will increase their speed by automatically detecting the system temperature. Both power and fan modules are hot-swappable, which minimizes the downtime of the DXS-3600 series. Standard and Enhanced Images The DXS-3600 switches provides two different software images. The Standard Image (SI) features a wide range of Layer 2, VLAN, multicasting, Quality of Service (QoS), security, data center, and static routing functions. The Enhanced Image (EI) features comprehensive IPv4/v6 routing including RIP, VRRP, OSPF, BGP, and L3 multicasting like IGMP, MLD, PIM-DM, SM, SDM, SSM, and DVMRP. The EI also supports L2/L3 MPLS VPN that enables the DXS-3600 series switches to also be deployed as the core router of an enterprise environment or an edge router of a MPLS environment. Data Center Features Data Center Bridging (DCB) is an essential set of enhancements to Ethernet for networking in data center environments. The DXS-3600 switches support several core components of Data Center Bridging (DCB) such as IEEE 802.1Qbb1, IEEE 802.1Qaz1, and IEEE 802.1Qau.1 IEEE 802.1Qbb (Priority Based Flow Control) provides flow control to ensure there is no data loss during network congestion. IEEE 802.1Qaz (Enhanced Transmission Selection) manages the allocation of bandwidth amongst different traffic classes. IEEE 802.1Qau (Congestion Notification) provides congestion management for data flows within network domains to avoid congestion. The DXS-3600 switches also support cut-through switching, which reduces latency in transmitting data in a network. Energy Efficient The DXS-3600 switches allow users to change the airflow by using different power and fan module sets. Selectable front-to-back or back-to-front airflow maximizes air cooling to provide more effective cooling throughout rack systems in data centers, where the switches are used, compared to side-to-side airflow. The switches also feature built-in smart fans; internal heat sensors monitor and detect temperature change, and react accordingly by utilizing different fan speeds for different temperatures. At lower temperatures, the fans will run slower and reduce the switch’s power consumption and noise.









Product features: 24 fixed SFP+ 10G ports with one expansion slot
Two AC/DC hot-swappable power modules for 1+1 power redundancy and load sharing
Three hot-swappable fan trays with front-to-back air?ow and N+1 cooling redundancy
