2. Introduction

CHAPTER 2: Introduction

2.1 Description

The Two-Port 10/100 Ethernet Switches are standalone, dual-port Ethernetto-Fast-Ethernet switches. In addition to enabling 10/100-Mbps and 100/100-

Mbps switching, the Switches can also extend the diameter of Fast Ethernet networks up to 100 km.

The Two-Port 10/100 Ethernet Switch is available in both a UTP and a fiberoptic version. Each copper port on the Two-Port 10/100 Ethernet Switch offers IEEE standard NWay auto-negotiation and is configurable for either half-duplex (for a 100-Mbps shared connection) or full-duplex (for a 200-

Mbps point-to-point collision-free connection). Each fiber port is configurable for only a 100-Mbps half-/full-duplex connection.

The Two-Port 10/100 Ethernet Switch uses self-learning of network addresses, and filters local traffic, collisions and error packets.

2.2 Features

• Complies with IEEE 802.3 and IEEE 802.3u standards.

• Uses UTP, multimode, or single-mode DSC connectors.

• Up to 110 km over single-mode fiber.

• Full-/half-duplex operation on all ports and speeds.

• NWay auto-negotiation for automatic speed and duplex configuration

(UTP only).

• Plug-and-play installation and support for all network operating systems and protocols.

• Status LEDs indicate switch operations for easy maintenance.

3. Applications

Figures 3-1 and 3-2 illustrate some of the Switch’s application possibilities.

Connections can include 10-Mbps and 100-Mbps servers, a Fast Ethernet backbone, 10/100-Mbps hubs or individual stations, all functioning in half-

/full-duplex mode. The medium can be either 10BASE-T/100BASE-TX UTP or 100BASE-FX fiber. The various fiber modules offer distance extensions in a 2-km to 110-km range (1.2 to 68.4 miles).

CHAPTER 4: Installation and Setup

4. Installation and Setup

Two-Port 10/100 Ethernet Switches are standalone units designed for 19" rack mounting. LED indicators help with installation and maintenance.

4.2 LEDs

Group 1 Right of UTP port (2); 10/100BASE-TX port LEDs

RX Data is being received from a connected hub or NIC card.

LINK Indicates connection to another switch, a hub, or a NIC.

COL/FD Bi-color LED. Yellow: port is in collision state. Green: port is configured for full-duplex communication.

100 Port is configured for 100 Mbps (UTP connection only).

Group 4 Right of fiberoptic port (5); 100BASE-FX port LEDs

These LEDs have the same functions as the Group 1 LEDs with the same names.

4.3 DIP Switches

The DIP switches change port configuration only during power-up.

In order to work in a fixed-rate mode, A/M (auto-negotiation/manual) must be set to UP. Then set H/F (Duplex) and 10/100 (Rate) to 10 half-, 10 full-,

100 half-, or 100 full-duplex modes.

To work in auto-negotiation mode, A/M must be set to DOWN. Then H/F can be set to the desired duplex mode (half/full).

CHAPTER 5: Troubleshooting

5. Troubleshooting

The Two-Port 10/100 Ethernet Switches are highly reliable. However, if a problem occurs, follow the steps below.

5.1 Problems

1) Symptom: None of the LEDs light or blink.

Cause:

Action:

The Switch isn’t getting power or isn’t working properly.

First, make sure the power cord is plugged in firmly.

Make sure the outlet works. If the cord and outlet are fine, call Black Box about getting a replacement Switch.

2) Symptom: The LINK LED does not light when…

Copper Port a) …the port is configured through DIP switches for 10 Mbps, no auto-negotiation, with a connection to a 10-Mbps PC adapter.

b) …the port is configured through DIP switches for 100 Mbps, no auto-negotiation, with a connection to a 100-Mbps PC adapter.

Cause:

Action: c) …the port is configured through DIP switches for 10 Mbps, no auto-negotiation, with a connection to a 10-Mbps hub.

d) …the port is configured through DIP switches for 100 Mbps, no auto-negotiation, with a connection to a 100-Mbps hub.

For a) and b), cable is not crossed or not connected securely.

For c) and d), cable is crossed or not connected securely.

Check cable connections in all four cases.

Fiber Port

…the Two-Port 10/100 Ethernet Switch’s port is connected to the fiberoptic port of any 100-Mbps hub or switch.

Cause:

Action: a) Fiberoptic cable is not connected securely.

b) The Two-Port 10/100 Ethernet Switch is defective.

a) Check cable connections.

b) Replace the Two-Port 10/100 Ethernet Switch.

3) Symptom: Copper port is configured through DIP switches to

100 Mbps, half-/full-duplex; 100 LED does not light.

Cause:

Action:

LED isn’t working properly.

Call Black Box about getting a replacement Switch.

15

TWO-PORT 10/100 ETHERNET SWITCHES

4) Symptom: COL/FD LED does not light Green when the copper/fiber port is configured through DIP switches to full-duplex

(with/without auto-negotiation).

Cause:

Action:

LED isn’t working properly.

Call Black Box about getting a replacement Switch.
