Black Box L2 Managed Gigabit Ethernet Switches w/(2) Dual-Media SFP Ports

Highlights
* Include 24 10-/100-/1000-Mbps copper ports and Small Form-Factor Pluggable (SFP) slots for adding the fiber SFP modules of your choice.

Further Details
- Support all IEEE 802.3/u/x/z Ethernet, Fast Ethernet, and Gigabit Ethernet specifications. Great for mixed-speed environments!
- 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. Support SNMP and Web-based management.
- Spanning Tree (802.1w) algorithms prevent network switching loops.
RoHS compliant.

For flexible and manageable port switching and bandwidth aggregation, order a BLACK BOX(r) L2 Managed Gigabit Ethernet Switch with Dual-Media SFP Ports.

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 16-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 24- or 48-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.
