1 Introduction This chapter provides an overview of the Matrix DFE‐Diamond 7KR4297‐02 and 7KR4297‐04 modules and optional XFP 10‐Gbps physical interface module. Note: Unless otherwise noted the term “DFE module” refers to both the 7KR4297-02 and 7KR4297-04 modules. For information about... Refer to page...
The DFE-Diamond 7KR4297-02 and 7KR4297-04 Modules The DFE-Diamond 7KR4297-02 and 7KR4297-04 Modules This section provides an overview of the 7KR4297‐02 and 7KR4297‐04 DFE‐Diamond modules shown in Figure 1‐1 and Figure 1‐2, as well as the optional XFP physical interfaces (PHYs). For information about the DFE‐Diamond module features and how to configure them, refer to the Enterasys Matrix DFE‐Diamond/Platinum Series Configuration Guide.

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.
2 Network Requirements Before installing the module, review the requirements and specifications referred to in this chapter concerning the following: For information about... Refer to page... XFP 10-Gigabit Ethernet 2-1 Module Placement in a Matrix E7 Chassis 2-2 The network installation must meet the requirements to ensure satisfactory performance of this equipment. Failure to do so will produce poor network performance. .
Module Placement in a Matrix E7 Chassis The uplinks have one fiber‐optic interface with an LC connector. Depending on the XFP and fiber‐ optic cable used, the signal can be driven to a maximum distance of 33 m (108 ft) to 40 kilometers (24.85 miles). The device at the other end of the fiber optic connection must be a standards‐compliant product with a matching XFP interface.
3 Installation Electrical Hazard: Only qualified personnel should perform installation procedures. Riesgo Electrico: Solamente personal calificado debe realizar procedimientos de instalacion. Elektrischer Gefahrenhinweis: Installationen sollten nur durch ausgebildetes und qualifiziertes Personal vorgenommen werden. Important Notice Read the Release Notes associated with the DFE-Diamond module to check for any exceptions to the supported features and operation documented in this guide.
Unpacking the DFE-Diamond Module Unpacking the DFE-Diamond Module Unpack the DFE‐Diamond module as follows: 1. Open the box and remove the packing material protecting the DFE‐Diamond module. 2. Verify the contents of the carton as listed in Table 3‐1. Table 3-1 Carton Contents Item Quantity 7KR4297-02 or 7KR4297-04 DFE-Diamond module 1 Customer Release Notes 1 3. Remove the tape seal on the non‐conductive bag to remove the DFE‐Diamond module. 4.
Backplane Connections and Installation Rules Figure 3-1 Installing an XFP 2 TX RX 1 3 TX 1 XFP module 2 Port slot RX 3 Release handle Removing an XFP Module To remove an XFP from the module port, refer back to Figure 3‐1 and proceed as follows: Caution: The XFP module and DFE module are sensitive to static discharges. Use an antistatic wrist strap and observe all static precautions during this procedure. Failure to do so can result in damage to the XFP module and DFE module.
Backplane Connections and Installation Rules The DFE FTM bridging modules have a connection to both FTM1 and FTM2 backplanes, which enables them to switch 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‐Diamond module management entity.
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.
Installing Module into Matrix E7 or Matrix N7 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 a DFE‐Diamond bridging module is installed in slot 2, enabling all modules to communicate with each other. Rule: In this example, the 7H4382‐49 DFE‐Diamond bridging module serves as both the FTM1‐to‐ FTM2 bridge and the five‐to‐seven slot proxy bridge.
Installing Module into Matrix E7 or Matrix N7 Chassis Installation To install the module, refer to Figure 3‐2 and proceed as follows: Caution: To prevent damaging the backplane connectors in the following step, take care that the module slides in straight and properly engages the backplane connectors. Ensure that the top lever lines up with the desired slot number located on the front panel of the chassis. Refer to Figure 3-2.

Installing Module into Matrix N3 Chassis Installing Module into Matrix N3 Chassis Caution: Failure to observe static safety precautions could cause damage to the DFE-Diamond module. Follow static safety handling rules and wear the antistatic wrist strap. Do not cut the non-conductive bag to remove the DFE-Diamond module. Sharp objects contacting the board or components can cause damage.
Connecting to the Network Connecting to the Network Note: If the DFE-Diamond 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 DFEDiamond/Platinum Series Configuration Guide for the configuration information. For details on how to obtain manuals, refer to “Related Documents” on page xii.

At the other end of the fiber‐optic cable, attach the SC connector to the other device. 4. Verify that a link exists by checking that the port RX LED is on (flashing amber, blinking green, or solid green). If the RX LED is off, there is no link.
Connecting to COM Port for Local Management • RJ45‐to‐DB25 female adapter • RJ45‐to‐DB25 male adapter With a UTP straight‐cable with RJ45 connectors and RJ45‐to‐DB9 adapter, you can connect products equipped with an RJ45 COM port to an IBM or compatible PC running a VT series emulation software package.
