Safety Information
Class 1 Laser Transceivers
The single mode interface modules use Class 1 laser transceivers.
Read the following safety information before installing or operating these modules.
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser transceivers comply with the following safety standards:
• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
• IEC Publication 825 (International Electrotechnical Commission).
• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered hazardous.
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 10‐6 watts.
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‐2 or 8 x 103 W m2 sr‐1. 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.

Secure Networks Policy Support
Switch Configuration Using CLI Commands
The CLI commands enable you to perform more complete switch configuration management tasks.
For CLI command set information and how to configure the module, refer to the Enterasys Matrix DFE‐Gold Series Configuration Guide.
Secure Networks Policy Support
Policy Enabled Networking manages the allocation of networking infrastructure resources in a secure and effective manner. Using Secure Networks Policy, an IT Administrator can predictably assign appropriate resources to the Users, Applications, and Services that use the network; while blocking or containing access for inappropriate or potentially dangerous network traffic. Using this technology it is possible, for the first time, to align IT services with the needs of specific users and applications, and to leverage the network as a key component of the organization’s security strategy.
The Secure Networks Policy Architecture consists of 3 components: Classification Rules, Network Services, and Behavioral Profiles. These are defined as follows:
•
Classification Rules determine how specific traffic flows (identified by Layer 2, Layer 3, and Layer 4 information in the data packet) are treated by each Switch or Router. In general, Classification Rules are applied to the networking infrastructure at the network edge/ingress point. •
Network Services are logical groups of Classification Rules that identify specific networked applications or services. Users may be permitted or denied access to these services based on their role within the organization. Priority and bandwidth rate limiting may also be controlled using Network Services. •
Behavioral Profiles (or roles) are used to assign Network Services to groups of users who share common needs–for example Executive Managers, Human Resources Personnel, or Guest Users. Access, resources, and security restrictions are applied as appropriate to each Behavioral Profile. A variety of authentication methods including 802.1X, EAP‐TLS, EAP‐TTLS, and PEAP may be used to classify and authorize each individual user; and the IT Administrator may also define a Behavioral Profile to apply in the absence of an authentication framework.
Standards Compatibility
The DFE modules are fully compliant with the IEEE 802.3‐2002, 802.3ae‐2002, 802.1D‐
1998, 802.3af‐2003, and 802.1Q‐1998 standards. The DFE modules provides IEEE 802.1D‐1998 Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions.

Link Aggregation
Link Aggregation
Link Aggregation is a method of grouping multiple physical ports on a network device into one logical link according to the IEEE 802.3ad‐2002 standard. Because Link Aggregation is standards based, it allows for automatic configuration with manual overrides (if applicable), and can operate on 10 Mbps, 100 Mbps, or 1000 Mbps Ethernet full duplex ports. Thus the network administrator can combine a group of five 100 Mbps ports into a logical link (trunk) that functions as a single 500 Mbps port. As long as the DFE modules agree on which ports are in the trunk, there are no problems with looping, and the Spanning Tree can treat this trunk as a single port.
In normal usage (and typical implementations) there is no need to enable/disable ports for Link Aggregation. The default values will result in the maximum number of aggregations possible. If the switch is placed in a configuration with its peers not running the protocol, no aggregations will be formed and the DFE modules will function normally (that is, Spanning Tree will block redundant paths).
For details about the commands involved with configuring the Link Aggregation function, refer to the Enterasys Matrix DFE‐Gold Series Configuration Guide.
Module Placement in a Matrix E7 Chassis
If you want to mix 6x1xxx, 6x2xxx, 6x3xxx, and 7H43xx‐xx series modules in the same Matrix E7 chassis, it is necessary to have a DFE module installed such as the 4G4285‐49, and also follow the module placement rules described in “DFE Module Placement and Installation Rules” on page 3‐3 to successfully bridge data traffic to some or all modules in the Matrix E7 chassis.
FTM Bridge Function and Optional NEM
The 4G4285‐49 DFE module does not support both the FTM bridging function and an optional network expansion module at the same time. With an optional network expansion module installed, the FTM bridging function is disabled. In either of these cases, all ports of the 4G4285‐49 remain active.
2-2
Network Requirements
10BASE-T Network
10BASE-T Network
When connecting a 10BASE‐T segment to any of the RJ45 fixed front‐panel ports of the 4G4285‐49 or 4G4205‐72, ensure that the network meets the Ethernet network requirements of the IEEE 802.3‐2002 standard for 10BASE‐T and 802.3af‐2003 standard for Power over Ethernet (PoE) power sourcing applications over Ethernet cabling. For more information about PoE, refer to Appendix C.
Note: If a port is to operate at 100 or 1000 Mbps, Category 5 cabling must be used.
Category 3 cabling does not meet 100 Mbps specifications. For 10 Mbps operation only,
Category 3 or Category 5 cabling can be used. Refer to the “100BASE-TX Network” on
page 2-3 for information about 100BASE-TX networks and cabling.
100BASE-TX Network
The fixed front panel ports of the 4G4285‐49 and 4G4205‐72 provide a connection that supports Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 100BASE‐TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. The fixed front‐panel ports also support the 802.3af‐2003 standard for Power over Ethernet (PoE) power sourcing applications over existing cabling. For more information about PoE, refer to Appendix C.
Note: The fixed ports of the modules support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 Mbps operation.
The modules are capable of operating at either 10, 100, or 1000 Mbps. The module
automatically senses the speed of the other device and adjusts its speed accordingly.
1000BASE-T Network
The 4G4285‐49 and 4G4205‐72 support 10/100/1000 Mbps via fixed RJ45 front panel connectors. These connectors support copper wire connections that can operate up to 1000 Mbps. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 network requirements for the devices to operate at Gigabit speed.
Note: The fixed ports of each module support Category 5 UTP cabling with an
impedance between 85 and 111 ohms for 100 and 1000 Mbps operation and can
automatically sense the port speed of the other device and adjusts its speed accordingly.

To ensure proper operation of the system, consider the following examples and rules for module placement in either chassis.
Example 1 (Figure 3-1, A)
Shows one module installed in the chassis. If the chassis is populated with only one 4xxxxx, it must be installed in slot 1. Rule: If only one 4xxxxx is installed in the chassis, it must be in slot 1. Always install a 4xxxxx in slot 1 of the chassis.
Example 2 (Figure 3-1, B)
Shows the chassis fully populated with 4xxxxx modules. All modules may be hot swapped, except the module in slot 1. If the module in slot 2 is designated as a redundant management module, the module in slot 1 may be hot swapped without shutting down the system. The module in slot 2 can be designated using the CLI command set license <license key>.
For information on how to use this command, refer to the Enterasys Matrix DFE‐Gold Series Configuration Guide. To access this guide on the web, refer to “Related Documents” on page xvi. Without a designated redundant management module in slot 2, removing the module in slot 1 will shut down the system.
Rule: Any module in a 4xxxxx system, including the management module in slot 1, may be hot swapped when there is a 4xxxxx module designated as a redundant management module in slot 2.

Installation
Installing the DFE Module into a Chassis
Example 3 (Figure 3-1, C)
Shows the primary management module missing from slot 1. As long as the module installed in slot 2 is designated as a redundant management module, the module in slot 1 can be removed without affecting system operation. However, if there is no module in slot 1, and the system is powered down, it cannot be restarted without a module in slot 1.
Caution: When installing a module into slot 1 of a non-operating chassis, it is strongly
recommended that the module have the desired version of firmware. Installation of a
replacement module into slot 1 of a non-operating chassis requires reconfiguration of the
system settings.
Precaución: Para instalar un módulo en la ranura 1 del chasis apagado, lo mejor es que
el módulo corresponda a la versión de firmware solicitada. Para instalar un módulo de
reemplazo en la ranura 1 del chasis apagado será necesario reconfigurar el sistema.
Rule: You cannot power up the system completely without a module in slot 1.
Example 4 (Figure 3-1, D)
Shows a chassis populated with 4xxxxx and 7xxxxx modules. DO NOT install 4xxxxx and 7xxxxx modules in the same chassis. In a 4xxxxx system, the chassis must be dedicated to DFE modules only. The chassis will be rendered inoperable if any other type of module (DFE‐Platinum or legacy modules, for example) are installed in the same chassis with DFE‐Gold modules.
Rule: In a 4xxxxx system, the chassis must be populated with only 4xxxxx boards to operate.
Installing the DFE Module into a Chassis

Connecting 48 Vdc Power for PoE Operation
The Matrix N5 (7C105‐P) chassis provides 48 Vdc to connected PDs (powered devices) by way of its backplane connection to a PoE‐compliant DFE module such as the 4G4285‐49 or 4G4205‐72.
For a Matrix E7 (6C107), Matrix N3 (7C103), and Matrix N7 (7C107) chassis, an optional external Enterasys Matrix N‐POE Power System is required to support PD connections to the 4G4285‐49. The power from the Matrix N‐POE Power System is supplied through a DC power cable connection to the front‐panel 48 Vdc Optional Power connector on the 4G4285‐49.
Warning: The 48 V wire harness contains two fuses, F11 and F29. If a fuse needs to be
replaced, it must be done by service personnel only. The fuse must be replaced with the
same Type and Rated fuse 20 A, 400 VDC.
Advertencia: E arnes del cable de 48V contiene dos fusibles, F11 y F29. Si un fusible
requiere ser reemplazado, debe ser hecho por personal de servicio unicamente. El fusible
debe ser reemplazado por uno del mismo tipo y clasificado como fusible de 20 A,
400 VDC.
Warnhinweis: Im Kabelbaum der 48V Zuleitung befinden sich 2 Sicherungen, F11 und
F29. Die Sicherung darf nur duch Fachpersonal getauscht werden und darf auch nur
durch den gleichen Typ ersetzt werden ( 20A / 400VDC ).
Note: If you are planning to install a PoE-compliant DFE module such as the 4G4285-49 in
a Matrix N3 (7C103) or Matrix N7 (7C107) chassis, install and connect the Matrix N-POE
Power System before connecting to PDs.
Refer to the Matrix N‐Series N‐POE Power System Installation Guide to install and connect a Matrix N‐POE Power System to the 4G4285‐49.
Note: When you install the 7H4385-49 in a Matrix N5 chassis, the 7H4385-49 48 Vdc
Optional Power Input does not support a connection from an external N-POE Power
System. The 48 Vdc power is supplied through the backplane of the N5 chassis from its
own 48 Vdc power modules. If none of these power modules are installed, then there is no
PoE support.

This section provides the procedures for connecting unshielded twisted pair (UTP) segments from the network or other devices to the 4G4285‐49 and 4G4205‐72 (“Connecting UTP Cables to DFE Modules” on page 3‐14).
Note: If the module is being installed in a network using Link Aggregation, there are rules
concerning the network cable and port configurations that must be followed for Link
Aggregation to operate properly. Before connecting the cables, refer to the Enterasys
Matrix DFE-Gold Series Configuration Guide for the configuration information. For details
on how to obtain manuals, refer to the “Related Documents” in About This Guide.
Connecting UTP Cables to DFE Modules
The fixed RJ45 front panel connections of the 4G4285‐49 and 4G4205‐72 are 10/100/
1000 Mbps ports. These ports have internal crossovers, and support automatic‐polarity sensing when configured for automatic‐negotiation.
If automatic‐negotiation is not activated on a port, use a straight‐through cable when connecting a workstation to the port. When connecting a networking device to the port, such as a bridge, repeater, or router, use a crossover cable.
If a port is set for auto‐negotiation, automatic‐polarity sensing is also activated. Automatic‐polarity sensing eliminates the need for a crossover cable, regardless if the connection is to another network device or a workstation.
Note: All RJ45 front panel ports on these DFE module support Category 5 Unshielded
Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. Category 3
cable may be used if the connection is going to be used only for 10 Mbps.
3-14
Installation
Connecting to the Network
The RJ45 fixed front panel connectors of the 4G4285‐49 and 4G4205‐72 also support PoE‐compliant connections to PDs (powered devices) that require 48 Vdc through the UTP cable to operate. When the 48 Vdc is available through the backplane of an N5 chassis or externally from an N‐POE Power System, you can verify if there is power at each port as described later in this procedure. Making the UTP Connections
Caution: To prevent damage to the equipment, do not connect the PoE supported ports
(1 through 48 or 72) to segments running between buildings. Keep connections to
equipment within the building.
Precaución: Para evitar que el equipo se dañe, no conecte los puertos PoE
(1 a 48 o 72) a segmentos que vayan de un edificio a otro. Mantenga las conexiones de
los equipos dentro del edificio.
To connect and verify UTP cable connections to RJ45 ports (1 through 48 or 72), refer to Figure 3‐4 and proceed as follows:
1.
Ensure that the device connected to the other end of the segment is powered ON.
2.
Insert the RJ45 connector on the twisted pair segment into the appropriate RJ45 port connector.

Using LANVIEW
DFE modules use a built‐in visual diagnostic and status monitoring system called LANVIEW. The LANVIEW LEDs (Figure 4‐1) allow quick observation of the network status to aid in diagnosing network problems. About the Management (MGMT) LED
The MGMT LED (shown in Figure 4‐1) indicates when the module is serving as the Management Module to control the management functions for all DFE modules in the chassis. The Management Module handles all IP requests to the chassis IP address, such as, but not limited to, PING, Telnet, SNMP, HTTP. The Management Module also handles the CLI configuration sessions through the console port. So, when you plug into a DFE module COM port to configure a DFE module in the chassis, it is handled by the Management Module regardless of the DFE module COM port that you use.

Overview of DFE Module Shutdown Procedure
Caution: Do not remove a DFE module from an operating chassis system before reading
the following information and instructions.
Precaución: Antes de retirar los módulos DFE del chasis en funcionamiento, lea las
siguientes instrucciones y la información suministrada.
The DFE modules installed in a Matrix E7, Matrix N3, Matrix N5, or Matrix N7 chassis are interdependent and operate under a single IP address as a single, distributed switch system (hardware, databases, and persistent storage). In this operating environment, the DFE module must shut down in an orderly fashion to ensure that the other modules in the system and other devices on the network are notified of the impending change. The device(s) can then make intelligent decisions and stabilize the network before the change is made; thereby increasing network availability.
You can shut down a DFE module in an operating system using the OFFLINE/RESET switch shown in Figure 4‐3. There are two procedures to shut down a DFE module.

Recommended Shutdown Procedure Using OFFLINE/RESET
Switch
Caution: Do not pull any DFE module out of an operating chassis before it has completed
its shutdown routine.
Precaución: No retire los módulos DFE del chasis en funcionamiento hasta que no se
haya terminado con la rutina de apagado.
Before pulling a DFE module out of a chassis, press or tap on its OFFLINE/RESET switch for less than 1 second. Its CPU LED changes from solid green to blinking between green and amber, indicating that the DFE module is shutting down. At the end of the DFE module shutdown routine, the CPU LED changes to a 67%/33% sequence of amber/off, respectively, indicating the module is in a halt state. In this time it is safe to restart or remove the DFE module from the chassis.
When a controlled shutdown is initiated from the OFFLINE/RESET switch, you have 60 seconds from the time the CPU starts flashing amber/off until the time the device is automatically restarted.
Note: The only safe time to pull a DFE module out of the chassis is when the CPU LED is
blinking amber. Otherwise, system operation will be interrupted.

Overview of DFE Module Shutdown Procedure
Last Resort Shutdown Procedure Using OFFLINE/RESET Switch
Caution: This method of shutting down a DFE module is not recommended except as a
last resort, because all processes currently running on the module will be interrupted
resulting in loss of frames.
Precaución: No se recomienda utilizar este método para apagar los módulos DFE- Gold.
Recurra a él sólo como último recurso, puesto que interrumpe todos los procesos del
módulo en funcionamiento, lo que podría resultar pérdidas de frames.
To reset a DFE module without it performing an orderly shutdown routine, press and hold the OFFLINE/RESET switch for approximately 6 seconds. Pulling any DFE module out of the chassis before it has been shut down is not recommended. The only safe time to pull a module out of the chassis is after the completion of a shutdown and the management LED is flashing amber/off.

About PoE (Power over Ethernet)
This appendix provides an overview of Power over Ethernet Technology and how it is implemented in relation to the 4G4285‐49 and 4G4205‐72 DFE modules.
Overview
Power over Ethernet (PoE) refers to the ability to provide operational power through the same Ethernet cabling to a PD (powered device) connected to a data network. Modern Ethernet implementations employ differential signals over twisted pair cables. This requires a minimum of two twisted pairs for a single physical link. Both ends of the cable are isolated with transformers blocking any DC or common mode voltage on the signal pair. PoE exploits this fact by using two twisted pairs as the two conductors to supply a direct current. One pair carries the power supply current and the other pair provides a path for the return current. While several proprietary legacy implementations of PoE have been deployed by LAN equipment vendors, in 2003 the IEEE published the IEEE 802.3af‐2003 specification, which is part of the 802.3 suite of standards.
The 4G4285‐49 and 4G4205‐72 are fully compliant with the IEEE 802.3af standard. They support the standard resistor based detection method, as well as AC disconnect capability. The 4G4285‐49 and 4G4205‐72 are also capable of supplying the maximum specified current to all ports simultaneously.
Each PD has a PDC (Powered Device Classification) that is transmitted to the DFE module for power management purposes. Table C‐1 lists the classifications and the associated power ranges.

Overview
Proprietary PD Detection
The 4G4285‐49 and 4G4205‐72 support a subset of the currently deployed proprietary PoE methods. This includes support for Cisco PDs, including a proprietary capacitor based detection scheme. Power Interface
The 4G4285‐49 and 4G4205‐72 can interface with an external 48V power supply that resides in a Matrix N5 chassis.
Matrix N5 Backplane 48 Vdc Interface
The 4G4285‐49 and 4G4205‐72 have a connector that interfaces with the backplane of the N5 chassis for 48 Vdc power. This power connection on the DFE modules is fused, has EMI suppression components for this interface, and can support a sustained output current of 20 A.
Front Panel 48 Vdc Interface
The 48 Vdc Optional Power Input connector on the 4G4285‐49 front panel provides a power interface connection for an Enterasys Matrix N‐POE Power System, which provides the 48 Vdc, 20 Amperes of power and return as well as the power supply status signals. The status signals indicate the presence and operating state of each Matrix N‐POE Power System power supplies. This 48 Vdc Optional Power Input interface is not fused as the N‐PoE Power System has a circuit breaker for each PoE switch module power feed.
Warning: The DFE module is shipped with a cover over its 48 Vdc Optional Power Input
connector. Do not remove this cover when the DFE module is installed in an N5 chassis.
This cover is removed only when you connect a 48 Vdc power cable from the Enterasys
N-POE Power System.
Advertencia: El modulo DFE es embarcado con una cubierta sobre su conector de poder
opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un
chassis N5. Esta cubierta debe removerse unicamente cuando se conecta el cable de
poder de 48 Vdc hacia el Sistema de Enterasys de Energia por Cable (Enterasys N-POE
Power System).
Warnhinweis: Im Auslieferungszustand der DFE Module stülpt eine Schutzkappe über
dem 48V Gleichspannungs-Anschluss, die nur dann abgezogen werden darf, wenn ein
Enterasys N-POE Power System angeschlossen wird. Keinesfalls darf diese Schutzkappe
abgezogen werden, wenn das DFE Modul in einem N5 Chassis installiert wird.
