that are shared with four SFP transceiver slots (see Figure 1, Ports 21­24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet
hot-swappable expansion modules (LGB6001C), and two stacking ports. Units
can be stacked up to eigh t h i gh
48 Gbps stack backplane.

The switches include an SNMP-based management agent embedded on the m ain

These Gigabit E t hernet s w it c hes employ a wire-speed, non -bloc kin g s w i tchi ng
fabric. This permits simultaneous wire-speed transport of multiple packets at low
latency on all ports. The switches also feature full-duplex capability on all ports,
which effectively doubles the bandwidth of each connection.

For
communications within the same VLAN, they use store-and-forward switching to
ensure maximum data integrity. With store-and-forward s witching, t he entire
packet must be r ec ei ved into a buffer and checked for validit y before being
forwarded. T h is pr even ts errors from being propagated t hr o ughout t h e netwo rk.

These switches include built-in stack ing ports that enable up to eight units to be
connected toget her thr ou gh a 48 Gbps stack backplane. T h e switch stac k can be
managed from a mast er u ni t usin g a sin gle I P a ddr ess.

NETWORK MANAGEMENT

These switches contain a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. They also include a management agent
that allows you to configure or monitor the switch using its embedded
management software, or via SNMP applications. To manage each switch, you
can make a direct connection to the console port (out-of-band), or you can
manage the switches through a network connection (in-band) using Telnet, the
on-board web agent, or SNMP-based network management software.

For a detailed desc ription of the management fea tures, refer to the Management
Guide.

10/100/1000BASE-T

The switches contain 24/48 RJ-45 ports that operate at 10 Mbps or 100 Mbps,
half or full duplex, or at 1000 Mbps, full duplex. Because all ports on these
switches support automatic MDI/MDI-X operation, you can use straight-through
cables for all network connections to PCs or servers, or to other switches or
hubs. (See “1000BASE- T Pin Assignments” on page 74.)

Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10, 100, or 1000 Mbps) can be
selected automatically. If a device connected to one of these ports does not
support aut o -negot ia tion , the communication m o de of that port can be
configured manually.

SFP TRANSCEIVER

The Small Form F acto r Pl uggabl e ( SFP ) transceiver slots are shared with fo ur of
the RJ-45 ports (ports 21–24 for the LGB6026A and ports 45–48 for the
LGB6050A). In its default configuration, if an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on its port, the associated
RJ-45 por t i s di s abl ed and cann ot be us ed. T h e s witch c an al so be c o nfi gu red to

These switches include two slots on the rear panel for hot-swappable single-port
10GBASE module s wit h SFP+ transcei vers. Refer to “Optional

Modules” on page 2 9 for more information on this module and the supported

10G transceivers.

STACKING

Each unit includes t w o sta c king po r ts t ha t pr o vi de a 48 Gbps hi gh- s peed serial
stack backplane connection. Up to eight 24-port or 48-port switches can be
connected together using optional stacking cables (LGB6000SC-001 or
LGB6000SC-004). Not e t hat th e 24 - por t and 48-port swi tches can be mixed in
the same stack. The Stack Master button enables one switch in the stack to
