Migrate to copper and fiber Gigabit Ethernet with these managed switches.
OVERVIEW
L2 Managed Gigabit Etheret Switches with (2) Dual-Media
SFP Ports and Web Smart Gigabit Switches provide a path for
migrating your network to Gigabit Ethernet. Manage both
types of switches through a Web interface or via SNMP. You
can also manage the L2 managed switches via a command-
line interface (CLI).
L2 Managed Gigabit Ethernet Switches
with (2) Dual-Media SFP Ports
Give important traffic priority and bandwidth when
switching Gigabit copper—and fiber!
Include 8, 16, 24, or 48 10-/100-/1000-Mbps copper ports
and two Small Form-Factor Pluggable (SFP) slots for adding
the fiber SFP modules of your choice.
For flexible and manageable port switching and
bandwidth aggregation, order a BLACK BOX® L2 Managed
Gigabit Ethernet Switch with (2) Dual-Media SFP Ports.
Available with 8, 16, 24, or 48 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’
dual SFP slots.
The 8-port version is an excellent choice for connecting
branch office machines to a larger MAN or WAN. What’s
more, because the 8-port version has a noise-free, fanless
design, it’s tailor-made for cramped SOHOs where you don’t
want a noisy network switch as a distraction. The larger
models are ideal 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
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.

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 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 (2) Dual-
Media SFP Ports also feature extensive error-tracking
capabilities. Port mirroring, for instance, helps you track errors
or abnormal packet transmission—all without interruping 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 Switch with (2) Dual-Media SFP
Ports use an 802.1w Rapid Spanning Tree (RST) algorithm for
creating a loop-free Layer 2 topology.
Web Smart Gigabit Switches
Web Smart Switches make migrating to Gigabit Ethernet
easy and affordable.
Setup is easy. Just use any Web browser to log onto the
built-in CLI interface to configure or monitor the switch.
All 10-/100-/1000-Mbps copper ports are autosensing for
speed and auto?negotiating for duplex. The switches also
feature Auto MDI/MDI-X, which means you never need a
crossover cable. Plus, you can populate the SFP slot with a
wide range of Gigabit and WDM uplink modules.
Tagged and port-based VLAN provides precise control over
network traffic segmentation and broadcast domains with up
to four trunk groups. You also get support for IEEE 802.x flow
control for full-duplex mode and collision-based backpressure
for half-duplex mode, plus Quality of Service (QoS) with a
two-level priority queue.
SNMP trap management alerts you instantly when
something goes wrong. Port mirroring helps to track network
errors or abnormal packet transmission.
