FEIP Receptacles, Cables, and Pinouts
Following are the three status LEDs and an explanation of what each indicates:
•MII—On when the MII port is selected as the active port by the controller.
•Link—When the RJ-45 or SC port is active, this LED is on when the port adapter is receiving a carrier signal from the network. When the MII port is active, this LED is an indication of network activity, and it flickers on and off proportionally to this activity.
•RJ45 (or FIBER on FEIP-1FX or FEIP-2FX)—On when the RJ-45 (or FIBER) port is selected as the active port by the controller.
FEIP Receptacles, Cables, and Pinouts
The two interface receptacles on the FEIP port adapter are a single MII, 40-pin, D-shell type receptacle, and a single RJ-45 receptacle (or SC-type for FEIP-1FX and -2FX optical-fiber connections). (See the 1FE-TX port adapter in Figure 10 and the 1FE-FX port adapter in Figure 11.)
You can use either one receptacle or the other; only one receptacle can be used at one time. Each connection supports IEEE 802.3u interfaces compliant with the 100BASE-X and 100BASE-T standards. The RJ-45 connection does not require an external transceiver. The MII connection requires an external physical sublayer (PHY) and an external transceiver. Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially.
Caution To prevent system problems, do not simultaneously connect cables to the RJ-45 (or SC) and MII receptacles on a single port adapter. Each port adapter (100BASE-FX or 100BASE-TX) can have either an MII attachment or an RJ-45 (or SC) attachment, but not both. The MII and RJ-45 (or SC) receptacles represent two physical connection options for one Fast Ethernet interface.
