Chapter 1: Introduction
Overview
The GSW-2692 switch is a stackable Fast Ethernet switch with 24 10BASE-T/
100BASE-TX ports and two 1000BASE-T ports*that operate in combination with two
Small Form Factor Pluggable (SFP) transceiver slots. The switch also provides two
1 Gbps built-in stacking ports for connecting up to eight units in a stack. The stacking
ports can also be used as normal Ethernet ports in standalone mode. The switch
also includes an SNMP-based management agent, which provides both in-band and
out-of-band access for managing the switch.
The GSW-2692 provides a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. It brings
order to poorly performing networks by segregating them into separate broadcast
domains with IEEE 802.3Q compliant VLANs, and empowers multimedia
applications with multicast switching and CoS services.**

Switch Architecture
The GSW-2692 employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all ports.
The switch also features full-duplex capability on all ports, which effectively doubles
the bandwidth of each connection.
The switch uses store-and-forward switching to ensure maximum data integrity. With
store-and-forward switching, the entire packet must be received into a buffer and
checked for validity before being forwarded. This prevents errors from being
propagated throughout the network.
The switch includes built-in stacking ports that enable up to eight units to be
connected together through a 4 Gbps stack backplane. The switch stack can be
managed from a master unit using a single IP address.
Network Management Options
With a comprehensive array of LEDs, the GSW-2692 switch provides “at a glance”
monitoring of network and port status. The switch can be managed over the network
with a web browser or Telnet application, or via a direct connection to the console
port. The switch includes a built-in network management agent that allows it to be
managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an
RS-232 serial port (DB-9 connector) on the front panel for out-of-band management.
A PC may be connected to this port
for configuration and monitoring out-of-band via a
null-modem serial cable. (See Appendix B for wiring options.)
For a detailed description of the advanced features, refer to the Management Guide.
Description of Hardware
10BASE-T/100BASE-TX Ports
The GSW-2692 switch base unit contains 24 10BASE-T/100BASE-TX RJ-45 ports.
All ports support automatic MDI/MDI-X operation, so you can use straight-through
cables for all network connections to PCs or servers, or to other switches or hubs.
(See “10BASE-T/100BASE-TX Pin Assignments” on page B-1.)
Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If
a device connected to one of these ports does not support auto-negotiation, the
communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.

1000BASE-T/SFP Ports
These are combination Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots (See Figure 1-1, Ports 25-26). If an SFP
transceiver (purchased separately) is installed in a slot and has a valid link on the
port, the associated RJ-45 port is disabled.
The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation, so 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 B-3.)
Stacking Ports
The unit provides two stacking ports that provide a 4 Gbps stack backplane
connection. Up to eight switches can be connected together using Category 5
Ethernet cables (purchased separately). The Master button enables one switch in
the stack to be selected as the master. This is the unit through which you manage
the entire stack.
The stacking ports can also be used as normal Ethernet ports in standalone mode
by pressing the Uplink button.
