VCCI Notice
This is a class A product based on the standard of the Voluntary Control Council for Interference by Information 
Technology Equipment (VCCI). If this equipment is used in a domestic environment, radio disturbance may arise. 
When such trouble occurs, the user may be required to take corrective actions.

BSMI EMC Statement — Taiwan
This is a class A product. In a domestic environment this product may cause radio interference in which case the user 
may be required to take adequate measures.

Safety Information
Class 1 Laser Transceivers
The single mode network expansion 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.

DFE-Platinum 7H4385-49 PoE Module

DFE-Platinum 7H4385-49 PoE Module
This section provides an overview of the 7H4385‐49 (Figure 1‐1). For information about 
the DFE module features and how to configure them, refer to the Enterasys Matrix 
DFE‐Platinum Series Configuration Guide.
The 7H4385‐49 has 48, 10BASE‐T/100BASE‐TX, PoE‐compliant ports that are accessed 
through the fixed front panel RJ45 connectors. There is also an slot for an optional 
network expansion module (NEM). The DFE module can be installed in a Matrix E7, 
Matrix N1, Matrix N3, Matrix N5, or Matrix N7 chassis.
The 7H4385‐49 DFE‐Platinum module also supports bridging between the Frame Transfer 
Matrix FTM1 and FTM2 backplanes in a Matrix E7 chassis. When mixing 6x1xxx, 6x2xxx, 
6x3xxx, and 7H43xx‐xx series modules in a Matrix E7 chassis, certain hardware 
installation configuration rules must be followed to ensure proper operation. These rules 
are covered in “Module Placement and Installation Rules” on page 3‐4.
Each of the fixed front panel ports can operate in either half‐duplex or full‐duplex mode 
of operation. The duplex mode can be determined by either auto‐negotiation or manual 
configuration. 
The DFE module ports can be configured to provide a high level of security, control traffic 
by limiting the rate of traffic accepted into the module and prioritizing traffic to expedite 
the flow of higher priority traffic through the module. For a complete list of capabilities, 
refer to the Enterasys Matrix DFE‐Platinum Series Configuration Guide.
The DFE module receives power and backplane connectivity when it is inserted into the 
Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1 chassis. The power to support 
the DFE module connections to 802.3af PoE‐compliant 48 Vdc PDs (powered devices) can 
be from the backplane of a Matrix N5 chassis or from an optional external Matrix N‐POE 
Power System.
The Matrix N‐POE Power System can provide 48 Vdc to support up to eight 
PoE‐compliant DFE modules. The connection from the N‐POE Power System is by way of 
the 48 Vdc ~ 20 A Maximum, optional Power Input connector on the front panel of the 
DFE module.
Note: Only an N-POE Power System can be connected to the 48 Vdc ~ 20 A Maximum
Optional Power Input connector of a series PoE-compliant DFE module such as the
7H4385-49.

The 7H4385‐49 DFE module supports up to 48, 10BASE‐T/100BASE‐TX switched ports 
connected through 48 fixed front panel connectors, and the bridge function between 
FTM1 and FTM2 connections on the chassis backplane. This enables bridging between 
6x1xxx, 6x2xxx, 6x3xxx, and 7x4xxx series modules installed in the same Matrix E7 
chassis. If a NEM is installed, additional connections are also available, depending on the 
NEM model.
Note: The 7H4385-49 does not support both the FTM bridge function and an optional
network expansion module at the same time. With a NEM installed, the FTM bridging
function is disabled. All ports remain active in either case.

The fixed front panel ports can also support connections to PoE‐compliant PDs when the 
module is connected to an external N‐PoE Power system. 

Management
Management of the module can be either in‐band or out‐of‐band. In‐band remote 
management is possible using Telnet, Enterasys Networks’ NetSight® management 
application, or WebView™ application. Out‐of‐band management is provided through 
the RJ45 COM (Communication) port on the front panel using a VT100 terminal or a 
VT100 terminal emulator.

Switch Configuration Using WebView
Enterasys Networks’ HTTP‐based Web management application (WebView) is an 
intuitive web tool for simple management tasks.

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‐Platinum Series Configuration Guide.

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 module provides IEEE 
802.1D‐1998 Spanning Tree Algorithm (STA) support to enhance the overall reliability of 
the network and protect against “loop” conditions.

Secure Networks Policy Support

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.

LANVIEW Diagnostic LEDs
LANVIEW diagnostic LEDs serve as an important troubleshooting aid by providing an 
easy way to observe the status of individual ports and overall network operations.

The network installation must meet the requirements to ensure satisfactory performance 
of this equipment. Failure to do so will produce poor network performance.
The Enterasys Matrix DFE-Platinum Series Configuration Guide and the Cabling Guide
referred to in the following sections can be found on the Enterasys Networks World Wide
Web site: http://www.enterasys.com/support/manuals
Refer to “Related Documents” on page xvi for additional information.

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.

Module Placement in a Matrix E7 Chassis

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‐Platinum 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, and successfully bridge data traffic to some or all modules in the 
chassis, it is necessary to have a bridging module (such as the 7H4385‐49) installed, and to 
follow the module placement rules described in “Module Placement and Installation 
Rules” on page 3‐4.

FTM Bridge Function and Optional Interface Module
The 7H4385‐49 DFE‐Platinum module does not support both the FTM bridging function 
and an optional NEM at the same time. With an optional NEM installed, the FTM 
bridging function is disabled. In either of these cases, all ports of the 7H4385‐49 remain 
active.

10BASE-T Network
When connecting a 10BASE‐T segment to any of the RJ45 fixed front‐panel ports of the 
7H4385‐49, 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 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.

Network Requirements

100BASE-TX Network

100BASE-TX Network
The fixed front panel ports of the 7H4385‐49 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 module support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 Mbps operation.
The module is capable of operating at either 10 or 100 Mbps. The module automatically
senses the speed of the other device and adjusts its speed accordingly.

Installing Optional Network Expansion Module (NEM)

Installing Optional Network Expansion Module (NEM)
Note: Install any optional equipment before proceeding to “Backplane Connections and
Installation Rules” on page 3-3 for an explanation of the rules to install different series
modules in a Matrix E7 chassis.

Refer to your release notes or the Enterasys Networks web site for the latest available 
network expansion module.
A Phillips screwdriver is required to install an optional network expansion module into 
the 7H4385‐49. 
Installing a NEM involves
•

removing the safety cover

•

removing the coverplate from the DFE module (7H4385‐49),

•

attaching the network expansion module, and

•

replacing the safety cover.

Refer to the installation instuctions shipped with the NEM for details.

Backplane Connections and Installation Rules
Note: A lowercase x indicates the general use of an alphanumeric character (for example,
6x1xx, the x’s indicate a combination of numbers or letters).

The following sections describe the FTM1 and FTM2 backplane connections, and the 
hardware configuration rules when installing first (6x1xx), second (6x2xx), third (6x3xx), 
and fourth (7xxxxx) generation modules into the same Matrix E7 chassis.

FTM1 and FTM2 Connectivity
The Matrix E7 (6C107) chassis has backplanes referred to as FTM1 and FTM2. The 7xxxxx 
DFE modules use FTM2 for high speed communication to each other and operate as one 
switching unit with a single IP address. The traffic through these modules does not 
connect to FTM1 except through an FTM bridging module such as the 7H4382‐25, 
7H4382‐49, 7H4383‐49, or the 7H4385‐49. Installation Guides for these bridging modules 
are located on the Enterasys Networks World Wide Web site: http://www.enterasys.com/
support/manuals.

DFE-Platinum Series Hardware Installation Guide

Backplane Connections and Installation Rules

These DFE modules have connections to both FTM1 and FTM2 backplanes, enabling them 
to route frames between the two backplanes and all modules in the 6C107 chassis. 
However, the older first (6x1xx), second (6x2xx), and third (6x3xx) generation modules 
are still managed using their own Local Management and are not subject to management 
by the DFE module management entity.
The Matrix N1 (7C111), Matrix N3 (7C103) and Matrix N7 (7C107) chassis have only FTM2 
connections and support only DFE modules. The Matrix N5 (7C105‐P) has FTM2 
connections and also supports PoE‐compliant DFE modules.

Module Placement and Installation Rules
The DFE‐Platinum modules can be installed in a Matrix E7 (refer to “Matrix E7 Chassis 
Module Placement,” below, for placement rules), Matrix N1, Matrix N3, Matrix N5, or 
Matrix N7 chassis. The Matrix N1, Matrix N3, Matrix N5, and Matrix N7 chassis support 
only DFE Series modules and there are no particular rules for installing modules.

Matrix E7 Chassis Module Placement
Depending on the modules being installed in the Matrix E7 chassis and to help ensure 
proper operation, consider the following examples and rules for module placement in the 
chassis. Figure 3‐1 shows six examples of chassis module placement. These examples are 
described below along with the applicable module placement rule.

Example 1 (Figure 3-1, A)
Shows the chassis fully populated with DFE modules (7xxxxx). These modules 
communicate with each other via the FTM2 chassis backplane and act as a single 
switching entity with one IP address. The DFE modules are configured using a Command 
Line Interface set of commands.
Rule: DFE modules can be installed in any available chassis slot in the Matrix E7 chassis.

Installation

Backplane Connections and Installation Rules

Example 2 (Figure 3-1, B)
Shows the chassis fully populated with third generation modules (6x3xx). These modules 
can also be installed in any available chassis slot in the Matrix E7 chassis, but operate as 
individual modules with separate IP addresses. Each module is configured using Local 
Management. 
Rule: The 6x3xx modules can be installed in any available chassis slot in the Matrix E7 
chassis. 

Example 3 (Figure 3-1, C)
Shows chassis slots 1 through 5 populated with first and second generation modules 
(6x1xx and 6x2xx). If a 6x1xx or 6x2xx series module is installed in slot 6 or 7, it will 
operate in standalone mode (no backplane connectivity). Like the 6x3xx modules, the 
6x1xx and 6x2xx modules operate as individual modules with separate IP addresses, and 
each one is configured using Local Management.
Rule: The 6x1xx and 6x2xx modules can communicate with each other when they are 
installed in chassis slots 1 through 5 in the Matrix E7 chassis. If installed in slot 6 or 7, they 
operate in standalone mode.

Example 4 (Figure 3-1, D)
Shows chassis slots 1 through 5 populated with a mix of 6x1xx, 6x2xx, and 6x3xx modules 
and only third generation modules in slots 6 and 7.
In this module arrangement, the 6x3xx module provides a proxy bridge, which enables 
the 6x1xx and 6x2xx modules to communicate with 6x3xx modules in slot 6 or 7. If more 
than one 6x3xx module is installed in slots 1 to 5, the module in the lowest numbered slot 
performs the proxy function for slots 6 and 7. Therefore, if a 6x3xx module is already 
performing the proxy function, and another 6x3xx module is inserted into a lower 
numbered slot, connectivity will be temporarily interrupted, as the new board takes over 
the proxy function. When a 6x3xx module in a lower numbered slot is removed, and there 
is a 6x3xx module in a higher numbered slot, communication is not interrupted.
For Local Management, plugging the Local Management connection into the 6x3xx 
modules will allow management connections to all 6x1xx, 6x2xx, and 6x3xx modules. If 
the Local Management connection is to a 6x1xx or 6x2xx board, only the modules in the 
first five slots will be recognized by the management client.
Rule: There must be at least one 6x3xx module in slots 1 through 5 to enable 
communications between the 6x1xx, 6x2xx, and 6x3xx modules.

DFE-Platinum Series Hardware Installation Guide

Backplane Connections and Installation Rules

Example 5 (Figure 3-1, E)
Shows chassis slots 1 and 5 populated with 6x2xx and 6x1xx modules, respectively; slots 2 
through 4 with DFE modules without a bridging module; and slots 6 and 7 with 6x3xx 
modules. 
In this module arrangement, the 6x2xx and 6x1xx modules in slots 1 and 5 can only 
communicate with each other, because there is no 6x3xx module in one of the first five 
slots to serve as the proxy bridge to communicate with the 6x3xx modules in slots 6 and 7. 
The 7x4xxx DFE modules in slots 2, 3, and 4 will operate under one IP address. Since there 
is no DFE bridging module, the DFE modules will not communicate with any other 
modules in the chassis.
Rule: In this example, there must be at least one 6x3xx series module, and a bridging 
module in any of the slots 1 through 5 to enable communications between all generations 
of modules in the chassis.

Example 6 (Figure 3-1, F)
The module arrangement in this example is similar to the one shown in Figure 3‐1, E and
described in Example 5. The only difference is that one of the bridging modules 
(7H4382‐25, 7H4382‐49, 7H4383‐49, or 7H4385‐49) is installed in slot 2, enabling all 
modules to communicate with each other. The 7H4382‐49 is used in this example. 
Rule: In this example, the bridging module serves as both the FTM1‐to‐FTM2 bridge and 
the five‐to‐seven slot proxy bridge. The 6x3xx does not serve as a proxy bridge in this 
configuration because the bridging module is in a slot with a lower number.

Connecting 48 Vdc Power for PoE Operation

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 7H4385‐49.
Note: When you install the 7H4382-49 in a Matrix N5 chassis, the 7H4382-49 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.
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.

For a Matrix E7, (6C107), Matrix N1 (7C111), 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 7H4385‐49. 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 7H4385‐49.
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 7H4385-49
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 7H4385‐49.

Installation

Connecting to the Network

Connecting to the Network
This section provides the procedures for connecting unshielded twisted pair (UTP) 
segments from the network or other devices to the 7H4385‐49 (“Connecting UTP Cables to 
7H4385‐49” on page 3‐15).
Note: If the DFE 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-Platinum 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 7H4385-49
The fixed RJ45 front panel connections of the 7H4385‐49 are 10/100 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 the 7H4385-49 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.

The RJ45 fixed front panel connectors of the 7H4385‐49 also support PoE‐compliant 
connections to PDs (powered devices) that require 48 Vdc through the UTP cable to 
operate. Whether 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.

Connecting to the Network

Making the UTP Connections
Caution: To prevent damage to the equipment, do not connect the PoE supported ports
(1 through 48) 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) 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), 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

Completing the Installation

Completing the Installation of a DFE Module in an Existing System
In an established DFE module system,
•

a DFE module is already established as the management module,

•

the passwords have already been set for various users,

•

the system IP address is set, and 

•

other system parameters have been set.

When you install a new DFE module into a system with an existing configured user 
account, the current system settings in that account are already recognized by the new 
DFE module and it will operate accordingly.
If you need to change any settings, you can connect a terminal to the local console port as 
described in “Connecting to COM Port for Local Management” on page 3‐20 to access 
system management, or use a Telnet connection to access the DFE module system 
management as described in Chapter 3 of the Enterasys Matrix DFE‐Platinum Series 
Configuration Guide.

Logging in with an Administratively-Configured User Account
If the device’s default user account settings have been changed, proceed as follows:
1.

At the login prompt, enter your administratively‐assigned user name and press 
ENTER.

2.

At the Password prompt, enter your password and press ENTER.

The notice of authorization and the Matrix prompt displays as shown back in Figure 3‐12.
Note: Users with Read-Write (rw) and Read-Only access can use the set password
command to change their own passwords. Administrators with Super User (su) access
can use the set system login command to create and change user accounts, and the set
password command to change any local account password. For information on the set
password and set system login commands, refer to Chapter 3 in the Enterasys Matrix
DFE-Platinum Series Configuration Guide.

The DFE module is now ready to be configured. For information about setting the IP 
address and configuring Telnet settings for remote access to DFE management, refer to 
Chapter 3 in the Enterasys Matrix DFE‐Platinum Series Configuration Guide. The CLI 
commands enable you to initially set up and perform more involved management 
configurations.

Using LANVIEW
The DFE module uses 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 4‐2. 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 7H4385‐49.

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 7H4385‐49 is fully compliant with the IEEE 802.3af standard. It supports the standard 
resistor based detection method, as well as AC disconnect capability. The 7H4385‐49 is 
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 7H4385‐49 supports 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 7H4385‐49 can interface with an external 48V power supply that resides in a Matrix 
N5 chassis or from a separate Matrix N‐POE Power System.

Matrix N5 Backplane 48 Vdc Interface
The 7H4385‐49 has a connector that interfaces with the backplane of the N5 chassis for 
48 Vdc power. This power connection on the 7H4385‐49 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 7H4385‐49 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.

PoE Port Status LEDs
The PoE port status of each 10/100 Mbps front‐panel port is indicated by the two‐color RX 
and TX LED display for each port. To observe the PoE port status indications, you must 
switch the DFE module management system from the default RX/ TX Status Mode to the 
PoE Port Status Mode using the DFE module front‐panel GROUP SELECT switch. The 
switch operation and a description of how to use the LED indications are described in 
“Using LANVIEW” on page 4‐1.
