Compliances and Safety Warnings
FCC - Class A
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause interference to
radio communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Subpart B of Part 15 of FCC Rules, which are designed to
provide reasonable protection against such interference when operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause
interference, in which case the user, at his own expense, will be required to take whatever
measures may be required to correct the interference. 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.
Warnings: 1. Wear an anti-static wrist strap or take other suitable measures to prevent
electrostatic discharge when handling this equipment.
2. When connecting this hub to a power outlet, connect the field ground lead
on the tri-pole power plug to a valid earth ground line to prevent electrical
hazards.

Chapter 1: Introduction
Overview
The Gigabit Ethernet Switches are intelligent multilayer switches (Layer 2, 3) with
24 10/100/1000BASE-T ports, four of which are combination ports
with four SFP transceiver slots (see Figure 1-1, Ports 21-24). The rear panel
provides a slot for single-port 10 Gigabit Ethernet hot-swappable expansion module,
and two stacking ports. Units are stackable up to eight high through built-in stacking
ports that provide a 40 Gbps stack backplane.
The switch systems include an SNMP-based management agent embedded on the
main board, which supports both in-band and out-of-band access for managing the
switch stack.
This switch system can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. They bring order to
poorly performing networks by segregating them into separate broadcast domains
with IEEE 802.1Q compliant VLANs, empower multimedia applications with
multicast switching and CoS services, and eliminate conventional router
bottlenecks.
*
that are shared
These switches 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, these switches can
significantly improve the throughput between IP segments or VLANs.

Switch Architecture
The Gigabit Ethernet Switches employ a wire-speed, non-blocking switching fabric.
This permits simultaneous wire-speed transport of multiple packets at low latency on
all ports. These switches also feature full duplex capability on all ports, which
effectively doubles the bandwidth of each connection.
For communications between different VLANs, these switches 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.
These switches include built-in stacking ports that enable up to eight units to be
connected together through a 40 Gbps stack backplane. The switch stack can be
managed from a master unit using a single IP address.
These switches include a slot on the rear panel for slide-in single-port 10GBASE
modules with Xenpak transceivers.
Network Management Options
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 RS-232 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 description of both switches’ advanced features, refer to the Gigabit
Ethernet Switch Management Guide.

Description of Hardware
10/100/1000BASE-T Ports
The switches contain 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 B-3.)
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
auto-negotiation, the communication mode of that port can be configured manually.
SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the
RJ-45 ports (ports 21~24). 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 port is disabled and cannot be used. The switch can also be
configured to force the use of an RJ-45 port or SFP slot, as required.
Stacking Ports
Each unit includes two stacking ports that provide a 40 Gbps high-speed serial stack
backplane connection. Up to eight 24-port switches can be connected together
using optional stacking cables. The Stack Master button enables one switch in the
stack to be selected as the Master.

Port and System Status LEDs
These switches include a display panel for key system and port indications that
simplify installation and network troubleshooting. The LEDs, which are located on
the front panel for easy viewing, are shown below and described in the following
