M7i Fixed Interface Card (FIC) Description

The Fixed Interface Card (FIC) is built into the router chassis.

The FIC receives incoming packets from the network and transmits outgoing packets to the network, providing support for Fast Ethernet ports or Gigabit Internet interfaces, depending on which version of the FIC is installed in the router.

The FIC also allows you to view alarm status at a glance and to perform some system control functions, such as taking PICs online and offline.

The FIC is located on the front of the chassis to the left of the Routing Engine and is not a field-replaceable unit (FRU).

Each FIC consists of the following components:

• The FIC has either two 100Base-TX Fast Ethernet ports or one Gigabit Ethernet port, depending on which type of FIC is installed in the router. FIC Specifications for the M7i Router describes the interface connectors. See Figure 1 and Figure 2.

  For more information about Fast Ethernet and Gigabit Ethernet interfaces, see the M7i Multiservice Edge Router PIC Guide. The networking interface on the FIC is configured the same way as a PIC. For more information about configuring interfaces see the Junos OS Network Interfaces Configuration Guide.

• Buttons on the FIC labeled PICS ON/OFF to take a Physical Interface Card (PIC) offline when it needs to be removed, or bring it online when it is replaced.
• Alarm LEDs and interface LEDs.
