Compliances and Safety Warnings
FCC - Class A
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
You are cautioned that changes or modifications not expressly approved by the party
responsible for compliance could void your authority to operate the equipment.
You may use unshielded twisted-pair (UTP) for RJ-45 connections - Category 3 or better
for 10 Mbps connections, Category 5 or better for 100 Mbps connections, Category 5, 5e,
or 6 for 1000 Mbps connections. For fiber optic connections, you may use 50/125 or 62.5/
125 micron multimode fiber or 9/125 micron single-mode fiber.

Power Cord Safety
Please read the following safety information carefully before
installing the switch:
WARNING: Installation and removal of the unit must be carried out by qualified personnel
only.
• The unit must be connected to an earthed (grounded) outlet to comply with international
safety standards.
• Do not connect the unit to an A.C. outlet (power supply) without an earth (ground)
connection.
• The appliance coupler (the connector to the unit and not the wall plug) must have a
configuration for mating with an EN 60320/IEC 320 appliance inlet.
• The socket outlet must be near to the unit and easily accessible. You can only remove
power from the unit by disconnecting the power cord from the outlet.

secondary connection point labelled Neutral, connected directly to earth (ground).
†Impédance à la terre
When using a fiber optic port, never look at the transmit laser while it is
powered on. Also, never look directly at the fiber TX port and fiber cable
ends when they are powered on.

Chapter 1: Introduction
Overview
The Gigabit Ethernet Switch is intelligent multilayer switch (Layer 2, 3) with 24 10/
100/1000BASE-T ports, four of which are combination ports*that are shared with
four SFP transceiver slots (see Figure 1-1, Ports 21-24). The rear panel provides
two slots for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and
two stacking ports. Units can be stacked up to eight high through the built-in stacking
ports that provide a 48 Gbps stack backplane.
The switch includes an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access for managing the stack.
The switch can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly
performing networks by segregating them into separate broadcast domains with
IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast
switching and CoS services, and eliminates conventional router bottlenecks.
The switch can be used to augment or completely replace slow legacy routers,
off-loading local IP traffic to release valuable resources for non-IP routing or WAN
access. With wire-speed performance for Layer 2 and Layer 3, the switch can
significantly improve the throughput between IP segments or VLANs.

Switch Architecture
The Gigabit Ethernet switch 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.
For communications between different VLANs, the switch use IP routing. For
communications within the same VLAN, they use 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 48 Gbps stack backplane. The switch stack can be
managed from a master unit using a single IP address.
The switch also includes two slots on the rear panel for slide-in single-port
10GBASE modules with XFP transceivers.
Network Management Options
The switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of
network and port status. It also includes 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 switch through a network
connection (in-band) using Telnet, the on-board web agent, or SNMP-based network
management software.
For a detailed description of GTL-2690’s advanced features, refer to the Gigabit
Ethernet Switch Management Guide.
