CLASS 1 LASER TRANSCEIVERS

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

C1G124-24

The C1G124-24 (Figure 1-2) has several types of port connections, which include

• twenty-four front panel RJ45 ports (10BASE-T/100BASE-TX/1000BASE-T compliant), and

• four expansion slots for optional Mini-GBIC interface modules.

The 10/100/1000 Mbp s fixed front panel ports can operate in either half-du plex or full-duplex mode, as determined by Auto-Negotiation.

On the C1G124-24, there are four additional slots labeled 21 through 24 for 1-Gbps fiber-optic connections via optional Mini-GBICs. However, the C1G124-24 can only support 24 slots. Using any or all of the four additional Mini-GBIC slots (21 through 24) automatically disables the same number of fixed RJ45 ports on a first-come, first-served basis during the system initialization process.

For example, connections made to Mini-GBICs in Mini-GBIC slot 21 and 23 before initializing the system, disables the fixed RJ45 ports 21 and 23. However, if connections are made after initialization, the Mini-GBIC connections are ignored and the fixed RJ45 ports 21 and 23 remain enabled.

The 10/100/1000 Mbp s fixed front panel ports can operate in either half-du plex or full-duplex mode, as determined by Auto-Negotiation.

A single LED is provided for each port to i ndicate link status and activity . The LED is lit when there is a link, and flashes when there is traffic.

C1H124-48 and C1G124-24

The switch functions can be configured using the WebView™ application, CLI switching commands, or SNMP.

Each device can be installed as a tabletop unit or installed into a standard 19-inch rack using the mounting hardware supplied with the rack.

The devices have power supply redundancy capability when connected to an optional external supply. If the resident power supply fails, the external power supply assumes the entire load of the device without interruption to network traffic. Each power supply supports its own ac input connection, which enables each power supply to be connected to a different ac power circuit for power source redundancy.

1.1.1 Mini-Gigabit Interface Connectors (Mini-GBICs)

The Mini-GBIC installs into a slot to provide 1000BASE-SX or LX network connections. There are different Mini-GBICs that can provide va rious types of connectors, such as an MT-RJ connector, LC connector that supports single-mode fiber-optic cabling, or LC connector that supports single or multimode fiber-optic cabling. Refer to Table A-2 for a list of supported Mini-GBICs.

1.2 HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION

The devices can auto-negotiate the ports’ mode of operation (half-duplex or full-duplex) between two devices according to IEEE 802.3 standards. During Auto-Negotiation, two devices automatically exchange information about their current operating mode. The Auto-Negotiation feature targets the maximum capability that can be reached between the two devices. For e xample, the devices can adjust to full-duplex operation when the device on the other end of the connection can also adjust from half-duplex to full-duplex. If the de vice on the other end of the connection can only operate in half-duplex mode, then the devices adjust to operate in half-duplex mode.

Introduction 1-3

Port Trunking

1.3 PORT TRUNKING

Port Trunking is used for load balancing or load sharing. Port Trunking provides a mechanism to group, or aggregate, multiple links of any technology together to scale the backbone bandwidth beyond the limitations of a single link. All links are user-configurable so administrators can scale the backbone bandwidth by adding Port Trunking. The benefits of Port Trunking include the following:

• All purchased bandwidth is used.

• Distributed, resilient links increase reliability and performance.

• Multiple technologies are supported within a single trunk for maximum flexibility.

1.4 REMOTE MONITORING (RMON)

The devices support the 1, 2, 3, and 4 Eth ernet RMON groups. The Statistics, Alarms, Ev en ts, and History groups are enabled on all ports by default.

1.5 PORT REDIRECT FUNCTION

The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting to ol used to map traffic from multiple source ports to a single destination port within the module. This feature allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe. The analyzer or RMON probe will see the data as if it were directly connected to the LAN se gment of the source port.

1.6 FLOW CONTROL

Flow control is a method of managing the flow of frames between two devices. It ensures that a transmitting device does not overwhelm a receiving device with data. This is accomplished by the transmitting device pausing its transmission while the receiving device processes the frames already received.

The devices support frame-based 802.3x flow control. Frame-based 802.3x flow control is supported on all Ethernet ports operating in the full-duplex mode. Flow control can be enabled or disabled on a port-by-port basis.

Back pressure flow control is not supported on ports operating in the half-duplex mode.

1-4 Introduction

802.1p Port Priority

1.7 802.1p PORT PRIORITY

The 802.1p port priority is used to assign a default priority to the frames received without priority information in their tag header, map prioritized frames to the appropriate transmit queues, and prioritize frames according to protocol type. The 802.1p port priority is part of the IEEE 802.1D standard.

1.8 MANAGEMENT

Management of the module can be either in-band or out-of-band. In-band remote management is possible through any SNMP-compliant Network Management Software, such as the Enterasys Networks’ NetSight™ management product. In-band management using Telnet and Enterasys Networks’ Webview™ is also provided. Out-of-band Local Management is provided through the RJ45 COM port on the front panel using a VT100 terminal or a VT100 terminal emulator.

Local Management provides the ability to manage the devices. Refer to the Matrix C Series Configuration Guide for more information.

1.9 SWITCHING OPTIONS

The devices provide 802.1Q switching between all of the front panel interfaces. In the 802.1Q mode (the default mode of operation), the device functions as an 802.1D switch until you configure VLANs. Up to 4094 VLANs can be configured. When VLANs are configured, the backplane ports are automatically configured as Q-trunk ports.

IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the replacement of existing equipment.

1.10 STANDARDS COMPATIBILITY

The C1H124-48 and C1G124-24 devices are fully compliant with the IEEE 802. 3, 802.3u, 802.3x,

802.1D, and 802.1Q standards. The devices provide IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The devices support a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), and RFC 1493 (Bridge MIB). A full suite of Enterasys Networks Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting. F o r information on how to extract and compile indi vidual MIBs, contact Enterasys Netw orks. Refer to the Release Notes for a complete list of supported MIBs.

Introduction 1-5

UPN Support

1.11 UPN SUPPORT

User Personalized Networks (UPN) is an architecture that allows network administrators to map network services to identified users, machines, peripherals and other network entities. UPN consists of three tiers:

• Classification rules make up the first or bottom tier. The rules apply to devices in the UPN

environment, su ch as switches and routers. The rules are designed to be implemented at or n ear the user’s point of entry to the network. The rules are typically at Layer 2, 3, or 4 of the OSI network model.

• The middle tier is Services, which allows multiple classif ication rules to be aggregated. Services

can include e-mail and Internet access.

• Roles, or Behavioral Prof iles make up the top tier. The roles assign services to various business

functions or departments, such as executive, sales, and engineering.

To implement most roles, UPN requires authentication such as 802.1x using EAP-TLS, EAP-TTLS, or EAP-PEAP. Authorization information, attached to the authentication response, determines the application of the UPN policy. One way to communicate the authorization information is to include the Policy Name in a RADIUS Filter-ID attribute. A UPN administrator can also define a role to be implemented in the absence of an authentication and authorization.

Refer to the release notes shipped with the module for details. The rules can only be implemented on the Matrix system by the Enterasys NetSight Policy

Manager, which is described on the web site at www.enterasys.com/netsight

3.5.2 Connecting Fiber-Optic Cables to MT-RJ Ports

WARNING: Mini-GBICs use Class 1 lasers. Do not use optical instruments to view the

laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the out put opt ical port, powe r m ust be remo ved from the network adapter.

This section contains the procedures for connecting a 1000BASE-SX multimode fiber-optic segment from the network or other devices to an MT-RJ port connector of a Mini-GBIC (MGBIC-MT01) in front panel port 50 or 52.

Each fiber-optic link consists of two fiber-optic strands within the cable:

• Transmit (TX)

• Receive (RX)

The transmit strand from a device port connects to the receive port of a fiber-optic Fast Ethernet device at the other end of the segment. The recei ve strand of the applicable MT-RJ port connects to the transmit port of the fiber-optic Fast Ethernet device.

Enterasys Networks recommends labeling fiber-optic cables to indicate receive and transmit ends. Many cables are pre-labeled, providing matching labels or tapes at both ends of each strand of cable.

3-12 Hardware Installation

Connecting to the Network

To connect an MT-RJ cable to a fixed MT-RJ connector of a Mini-GBIC, refer to Figure 3-12 and proceed as follows:

1. Remove the protective covers (not shown) from the front panel MT-RJ fiber-optic port

52 in this example) and from the connectors

NOTE: Leave the protective co vers in place when the connectors are not in use to prevent contamination.

CAUTION: Do not touch the ends of the fiber-optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data transmissions. If the ends of the fiber-optic strands become contaminated, use a canned duster to bl ow the surfaces clean. A fiber-port cleaning swab saturated with optical-grade isopropyl alcohol may also be used to clean the ends.

2. Insert the MT-RJ cable connector

NOTE: To remove the MT-RJ cable connector , press on its release tab and pull out the cable connector.
