Cisco Systems VIP-FE-TX/4E manual 4E Port Adapter Description and 10BASE-T Specifications

VIP Port Adapter Functions

Both Ethernet and IEEE 802.3 are broadcast networks, which means that all stations see all transmissions. Each station must examine received frames to determine whether it is the intended destination and, if it is, pass the frame to a higher protocol layer for processing. IEEE 802.3 specifies several different physical layers, and Ethernet defines only one. Each IEEE 802.3 physical layer protocol has a name that summarizes its characteristics in the format speed/signaling method/segment length where speed is the LAN speed in Mbps, signaling method is the signaling method used (either Baseband or Broadband), and segment length is the maximum length between stations in hundreds of meters.

4E Port Adapter Description and 10BASE-T Specifications

The 4E port adapter is currently only available on the VIP-FE-TX/4E, which has a single Fast Ethernet (FE-TX) port adapter in port adapter slot 0, and a single Ethernet 10BASE-T (4E) port adapter in port adapter slot 1. (For a description of the FE-TX port adapter, refer to the section “FE-TX Port Adapter” on page 29.) Figure 24 shows the VIP-FE-TX/4E.

Note VIP configurations using only one 4E port adapter and a port adapter blank, or two 4E port adapters, are currently not supported. The FE-TX and 4E port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each port adapter’s faceplate.
