Connectivity Connectivity 4H4285-49 Depending on how the 4H4285‐49 is configured, it can support up to: • 48, 10BASE‐T/100BASE‐TX switched ports connected through 48 fixed front panel connectors, or • 48, 10BASE‐T/100BASE‐TX switched ports and an optional network expansion module (NEM). 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 or installed in an N5 chassis.
Standards Compatibility 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.
2 Network Requirements Before installing the module, review the requirements and specifications referred to in this chapter concerning the following: Refer to page... For information about... Link Aggregation 2-1 10BASE-T Network 2-2 100BASE-TX Network 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.
10BASE-T Network 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).
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 shipped with the DFE module to check for any exceptions to the supported features and operation documented in this guide.

C About PoE (Power over Ethernet) This appendix provides an overview of Power over Ethernet Technology and how it is implemented in relation to the 4H4285‐49. Overview Power over Ethernet (PoE) refers to the ability to provide operational power to a device connected to a data network using the same cabling that provides the data interface. Modern Ethernet implementations employ differential signals over twisted pair cables. This requires at a minimum of two twisted pairs for a single physical link.
Proprietary PD Detection Proprietary PD Detection The 4H4285‐49 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 4H4285‐49 can interface to an external 48 Vdc supply that resides in a Matrix N5 chassis or from a separate Matrix N Series N‐POE Power System.
PoE Port Status LEDs 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 button. The switch operation and a description of how to use the LED indications are described in “Using LANVIEW” on page 4‐1.
