Fast Ethernet Interface Processor (FEIP) Installation and Configuration  15

The FEIP provides up to two 100-Mbps, IEEE 802.3u Fast Ethernet interfaces. (Figure 8 shows a
two-port 100BASE-TX FEIP.)

The FEIP is available in the following fixed configurations:

•

CX-FEIP-1TX(=)—FEIP with one 100BASE-TX port adapter in port adapter slot 0

•

CX-FEIP-2TX(=)—FEIP with two 100BASE-TX port adapters

•

CX-FEIP-1FX(=)—FEIP with one 100BASE-FX port adapter in port adapter slot 0

•

CX-FEIP-2FX(=)—FEIP with two 100BASE-FX port adapters

Each 100BASE-TX interface has an RJ-45 connector to attach to Category 5 unshielded twisted-pair
(UTP) for 100BASE-TX, and an MII connector that permits connection through external
transceivers to multimode fiber for 100BASE-FX, or to Category 3, 4, and 5 UTP or shielded
twisted-pair (STP) for 100BASE-T4 physical media. Each 100BASE-TX or 100BASE-FX interface
on an FEIP can be configured at 100 Mbps, half duplex or full duplex, for a maximum aggregate
bandwidth of 200 Mbps.

To prevent oversubscribing the FEIP, we recommend that you do not operate both FE interfaces on

an FEIP in full-duplex mode.

For pinouts, refer to the section “FEIP Receptacles, Cables, and Pinouts” on page 17. The standard
dynamic random access memory (DRAM) size for the FEIP is 8 megabytes (MB). You can install
FEIPs in any available interface processor slots.
