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

What Is the FEIP2?

Note Each of the FEIP2-2FX’s two 100BASE-FX interfaces uses the MII connector like the

FEIP2-2TX, but the FEIP2-2FX has an SC-type ﬁber-optic connector in place of the RJ-45

connector. Either the MII LED or the RJ-45 (or FIBER) LED should be on at any one time; never

both.

Caution To prevent system problems, do not simultaneously connect cables to the RJ-45 (or SC)

and MII receptacles on a single FEIP2 FE interface. Each FE interface (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 FE interface.

FEIP2 LEDs

The FEIP2 contains the enabled LED and a bank of three status LEDs for each of the two FE

interfaces (located between the two receptacles on each FE interface). After system initialization,

the enabled LED goes on to indicate that the FEIP2 has been enabled for operation. (The LEDs are

shown in Figure 9.)

The following conditions must be met before the enabled LED goes on:

• The FEIP2 is correctly connected and receiving power

• The FEIP2 card contains a valid microcode version that has been downloaded successfully

• The bus recognizes the FEIP2.

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED

does not go on.

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 FE interface 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 FEIP2-2FX)—On when the RJ-45 (or FIBER) port is selected as the active

port by the controller.
