Second-Generation Fast Ethernet Interface Processor (FEIP2) Installation and Configuration 17

What Is the FEIP2?

• FEIP2-2FX(=)—FEIP2 with two, 100BASE-FX FE interfaces (See Figure 8.)

Figure 8 Fast Ethernet Interface Processor (FEIP2-2FX)

Each 100BASE-FX interface on the FEIP2-2FX has an SC-type ﬁber-optic connector for

100BASE-FX, 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.

For pinouts, refer to the section “FEIP2 Receptacles, Cables, and Pinouts” on page 19. The

standard dynamic random access memory (DRAM) size for the FEIP2 is 8 megabytes (MB), and

the standard static random access memory (SRAM) size for the FEIP2 is 1 MB. You can install

FEIP2s in any available interface processor slots.

Note Each FEIP2 model is a ﬁxed conﬁguration; therefore, individual FE interfaces are not

available as spare parts, do not have handles, and are not ﬁeld replaceable or removable. The entire

FEIP2 assembly must be treated as a ﬁeld-replaceable unit (FRU).

Caution To prevent system problems, we recommend that you not attempt to remove an FEIP2’s

FE interface and replace it with another, nor attempt to mix 100BASE-TX and 100BASE-FX FE

interfaces on the same FEIP2.
