The NM-1E is a Cisco 1-port Ethernet network module for the Cisco 2600 series and 3600 series routers. Its single Ethernet port can use either the attachment unit interface (AUI) DB-15 connector on the right side of the module or the 10BASE-T (RJ-45) connector next to it. Only one of the two connectors is active at a time.
The module detects the type of network connection automatically and no media type is set in software. If cables are plugged into both connectors, the 10BASE-T connection is chosen. In software the active port is identified by port type Ethernet, the slot number of the module and port number 0.
The AUI connector takes an AUI cable to an Ethernet transceiver, and a jackscrew in a separate bag replaces the AUI slide latch when the transceiver cable has thumbscrew connectors. The 10BASE-T port uses Category 5 or better unshielded twisted-pair cable to a hub or other network device. The enable (EN) LED means the module passed its self-tests, and the ACT and LINK LEDs cover the port.
The 4-port Ethernet model is the NM-4E, and the model with one Ethernet port and two WAN card slots is the NM-1E2W. Further network modules are in Cisco interface cards.
