The NM-4E is a Cisco 4-port Ethernet network module for Cisco 2600 series and 3600 series modular routers. It provides four Ethernet connections numbered 0, 1, 2 and 3. Port 0 can use either an AUI or a 10BASE-T interface, while ports 1, 2 and 3 use 10BASE-T connectors only and have no AUI connector.
The 10BASE-T ports are RJ-45 connectors, color-coded yellow, and take Category 5 or better unshielded twisted-pair cable. The AUI option on port 0 is a DB-15 connector that connects through an AUI cable to an Ethernet transceiver. Port 0 can use only one of its two connectors at a time. The module detects the type of network connection automatically, and no media type has to be chosen in software.
An enable (EN) LED lights when the module has passed its self-tests and is available to the router. Every port also has an activity (ACT) LED for sent and received Ethernet traffic and a link (LINK) LED for the link integrity signal from the hub, which applies to 10BASE-T only.
For a single Ethernet port with the same AUI and 10BASE-T choice, see the NM-1E 1-port Ethernet network module. Browse the rest of the module range in the Cisco interface card category.
