Caution
Only use small form-factor pluggable modules (SFPs) supplied by Cisco in Cisco 12000 Series Routers.
Each SFP module contains an internal serial number that is security programmed by the SFP module
manufacturer with information that provides a way for Cisco (through the Cisco IOS software) to
identify and validate the SFP module as a module type that is qualified by Cisco to operate with Gigabit
Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) do not work.

8-Port Fast Ethernet Line Card
The 8-Port Fast Ethernet line card provides eight Fast Ethernet (IEEE 802.3u) interfaces that operate at
a full-duplex data rate of 100 Mbps each.
a full-duplex data rate of 100 Mbps each.
The 8-Port Fast Ethernet line card supports either copper or fiber-optic Fast Ethernet transceivers. The
fiber-optic 100BASE-FX interface supports multimode SC duplex connectors operating in half- or
full-duplex mode. The copper interface supports both half- and full-duplex 100BASE-TX standards that
use an RJ-45 connector.

There are two models, each with updated revisions (-B), of the 8-Port Fast Ethernet line card. The two
fiber-optic interface versions are functionally equivalent; the -B model contains some newer ASICs and
memory chips, however, and requires a later version of Cisco IOS. The copper interface versions are also
both functionally equivalent; the -B model contains some newer ASICs and memory chips and requires
a later version of Cisco IOS. The front panels are shown in
