Reading LED Indicators B-5
Interface Processor LEDs
The following sequence indicates that the CIP is starting to execute the microcode:
EIP LEDs
The EIP contains a bank of 18 LEDs: one horizontal row of three LEDs for each of the six Ethernet
interfaces, as shown in Figure B-6.
As with the other interface processors, the enabled LED goes on when the EIP is enabled for
operation. Three LEDs for each port indicate the following:
• Collision—A frame collision has been detected.
• Transmit—Frames are being transmitted.
• Receive—Frames are being received.

FEIP LEDs
The FEIP contains the enabled LED, standard on all interface processors, and a bank of three status
LEDs for the ports. After system initialization, the enabled LED goes on to indicate that the FEIP
has been enabled for operation. (The LEDs are shown in Figure B-7.) The following conditions must
be met before the enabled LED goes on:
• The FEIP is correctly connected to the backplane and receiving power.
• The FEIP contains a valid microcode version that has successfully been downloaded.
• The bus recognizes the FEIP.
If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED
does not go on.
