COMPLIANCES

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) cable for RJ-45

connections—Category 3 or greater for 10 Mbps connections, Category 5 for 100

Mbps connections and Category 5 or 5e for 1000 Mbps connections. Use 50/125 or

62.5/125 micron multimode fiber optic cable, or 9/125 micron single-mode cable,

for SFP transceiver connections.

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 switch 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.

ABOUT THE SWITCH

Overview

This switch is an ideal solution for delivering Internet access to

individual users in multi-dwelling or multi-tenant units (MDUs/

MTUs), such as apartment housing blocks, commercial buildings

or hotels. This switch provides rate-limitable connections to

individual users with secure port-to-port isolation between users

– all with conventional Ethernet cabling and adapters. At an

MDU/MTU site, up to 24 other switches can be cascaded from

one switch, providing broadband Internet access for up to 24

individual users on each switch.

Switch Architecture

The switch contains 24 10/100 Mbps Fast Ethernet ports on the

front panel. Each port can provide a dedicated link directly to an

end-user PC, or be attached to another Ethernet switch/hub at

the end-user’s premises and used as a shared link. The switch

completely eliminates the bottlenecks of dial-up internet access

by offering a configurable bandwidth of up to 100 Mbps full

duplex for each end-user connection. For all port connections, the

switch’s 8.8 Gbps bandwidth capacity is more than enough to

handle even the most demanding environments.

Auto-negotiation is used to select the optimal transmission speed

and communication mode for each connection. With

store-and-forward switching and flow control, maximum data

integrity is always maintained, even under heavy loading.

This switch includes two port: 1000BASE-SX and RJ-45. These

ports allow users the flexibility to use either fiber or copper

media.

The switch also supports a stacking module that can be installed

into slot M1. The stacking module allows up to eight units to be

linked together and managed from one unit using one IP address.

Management Options

This 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 the switch, you can make a

direct connection to the RS-232 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 Windows-based

network management software.

O

VER VI E W

The management agent provides a wide range of advanced

performance-enhancing features. Port-based VLANs provide

traffic security and efficient use of network bandwidth. QoS

priority queueing ensures the minimum delay for

mo v in g

real-time multimedia data through the switch. Flow control

eliminates the loss of packets due to bottlenecks caused by port

saturation. Port security is provided to filter unwanted traffic

from the switch.

Some of the switch’s advanced features are described below. For

a detailed description, refer to the Foundry EdgeIron User Guide.

VLANs

This switch supports up to 255 VLANs. A Virtual LAN is a

collection of network nodes that share the same collision domain

regardless of their physical location or connection point in the

network. By segmenting your network into VLANs, you can:

• Eliminate broadcast storms which severely degrade

performance in a flat network.

• Simplify network management for node changes/moves by

remotely configuring VLAN membership for any port, rather

than having to manually change the node’s physical

connection.

• Provide data security by restricting all traffic to the

originating VLAN, except where a connection is explicitly

defined via the switch’s routing service.

This switch supports Private VLANs as an extension of the

common VLAN. Private VLANs can be used to provide

port-based security and isolation between ports within a VLAN.

Private VLANs deliver per port security, requiring only one

VLAN on every switch, not every port. This feature greatly

A

BOUT

THE

S

WI TCH

minimizes the total number of VLANs required. Private VLANs

and normal VLANs can exist simultaneously in the same switch.

Multicast Switching

Specific multicast traffic can be assigned to its own VLAN to

ensure that it does not interfere with normal network traffic and

to guarantee real-time delivery by setting the required priority

level for the designated VLAN. The switch uses IGMP Snooping.

Traffic Priority

This switch provides Quality of Service (QoS) by prioritizing

each packet based on the required level of service, using four

distinct categories with Weighted Round Robin queuing. It uses

IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based

on input from the end-station application. These functions can be

used to provide independent priorities for delay-sensitive data

and best-effort data.

Description of Hardware

RJ-45 Ports

The switch base unit contains 24 10BASE-T/100BASE-TX RJ-45

ports. All of these 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 -2.)

Each of these ports support IEEE 802.3x auto-negotiation, so the

optimum transmission mode (half or full duplex), and data rate

(10 or 100 Mbps) can be selected automatically, if this feature is

also supported by the attached device. If a device connected to

one of these ports does not support auto-negotiation, the correct

speed will be sensed by the port, but the transmission mode will

default to half duplex.

D

ESCRI PTI ON

OF

H

ARDWARE

Each port also supports auto-negotiation of flow control, so the

switch can automatically prevent port buffers from becoming

saturated.

Port Status LEDs

The base unit also includes 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 tables.
