Details

  • Copper ports are autosensing for 10BASE-T/100BASE-TX/1000BASE-T.
  • Dual-media ports support SFPs or function as copper ports.
  • Also use in workgroups, office LANs, and larger metropolitan networks that carry higher-priority traffic for powerful applications.
  • Bundle multiple ports to create a single high-bandwidth port using 802.3ad Link Aggregate Control Protocol (LACP) aggregation.
  • Programmable higher layer classification and prioritization for reliable Quality of Service (QoS).
  • Ideal for use in VoIP real-time applications where info moves from Layer 2 to Layer 4.
  • Robust security with VLAN capabilities, as well as port security and IGMP snooping.
  • Easy to manage and configure. Supports SNMP and Web-based management.
  • Spanning Tree (802.1w) algorithms prevent network switching loops.
  • RoHS compliant.
  • Includes a 19" rackmount kit.

  • This fully manageable switch enables you to allocate bandwidth where you need it. Plus you can use the QoS features to switch packets efficiently for real-time applications.

    For flexible and manageable port switching and bandwidth aggregation, order a Black Box® L2 Managed Gigabit Ethernet Switch with Dual-Media SFP Ports.

    Available with 8, 12, 20, or 44 10-/100-/1000-Mbps copper ports, these Layer 2 manageable switches offer particular advantages in mixed-speed and legacy-integration environments. You can connect twisted-pair Ethernet, Fast Ethernet, and Gigabit Ethernet segments to devices on other ports or to a fiber optic backbone plugged into the switches' SFP slots.

    This 44-port version is an excellent choice for use in workgroups or WANs.

    For the SFP slots, just order the fiber SFP modules that best suit your application. We offer the 850-nm Multimode Gigabit SFP Module (LGB200C-MLC) and 1310-nm Single-mode Gigabit SFP Module (LGB200C-SLC10). (NOTE: For information on SFP module compatibility, including other modules from Black Box, contact our FREE Tech Support.)

    You can also provide more bandwidth to a specific application or segment with the switches. That's because they feature 802.3ad Link Aggregate Control Protocol (LACP) bandwidth aggregation, which enables you to combine Gigabit ports to create a multilink trunk for load sharing. It's especially beneficial in switch-to-switch cascading applications where you require higher full-duplex speeds.

    The size of the multilink load-sharing trunk depends on the switch you order. The 8-port model supports up to four Gigabit ports per a trunk for a bandwidth up to 8 Gbps. The 12-port model can be set up with up to eight Gigabit ports per a trunk for a bandwidth of up to 16 Gbps. For more LACP bandwidth, order the 20- or 44-port models, which each support up to 12 Gigabit ports per trunk.

    LACP not only increases link capacity, it also creates higher availability. And because the switches aggregate all traffic based on MAC addresses, they balance traffic loads efficiently.

    Along with Layer 2 802.1p Priority Queue control, the switches offer a much higher level of Quality of Service (QoS) support, so you can program a higher layer classification and ensure that traffic in real-time applications, such as Voice over IP (VoIP), receives higher priority.

    Broadcast/multicast storm suppression enables you to restrict excess traffic on your network. You can also control the rate limit for each switch port and set threshold values for the size of discarded packets. Jumbo frame support helps to ensure reliable data transmission, too. With this, you can set the switches to forward packets up to 9K in size before discarding them.

    The L2 Managed Gigabit Ethernet Switch with (2) Dual-Media SFP Ports also contain a number of security capabilities, including a Q-in-Q VLAN feature that's used to isolate traffic between different users, and 802.1x user authentication, which prevents unauthorized access via a network.

    In addition, with VLAN support for advanced 802.1Q (in the .1Q VLAN protocol), the switch enables you to limit broadcast traffic to within the same VLAN broadcast domain. And because the switches support Generic Attribute Registration Protocol (GARP) and Generic VLAN Registration Protocol (GVRP), they allow for a more efficient exchange of VLAN configuration data with other users and devices.

    You can also limit the number of MAC addresses assigned to each port, which, in turn, enables you to control the number of access stations for each port. This way, you not only establish an access mechanism by user and machine, you also control the number of access stations on your network.

    Monitor, configure, and control ports with ease. The switches support SNMP, Web-based management, and CLI management interfaces. You can also physically stack up to 16 of the switches and, using Virtual Stacking Management (VSM), manage them all via one IP address. In this configuration, the switches are seen as part of a logically segmented VLAN—an expanded network that doesn't require the expense or configuration of additional hardware to implement.

    The L2 Managed Gigabit Ethernet Switch with Dual-Media SFP Ports also feature extensive error-tracking capabilities. Port mirroring, for instance, helps you track errors or abnormal packet transmission—all without interrupting data flow in your networked switched environment.

    For mission-critical applications, use multiple switches and configure each with a redundant backup bridge path. Then, if a failure occurs on one switch, you'll still be able to guarantee the transmission and reception of packets via a secondary link on your network. For proper load balancing in VLAN applications, L2 Managed Gigabit Ethernet Switches with Dual-Media SFP Ports use an 802.1w Rapid Spanning Tree (RST) algorithm for creating a loop-free Layer 2 topology.

    For the SFP slots, just order the 1250-Mbps fiber SFP modules that best suit your application. (NOTE: For information on SFP module compatibility, including other modules from Black Box, contact our FREE Tech Support.)
