3: Operating the Gigabit Ethernet PCI Express Board
Using LEDs to Determine Board Functionality
The fiber-optic and copper Gigabit Ethernet boards have light-emitting diodes (LEDs)
that indicate whether the board is configured correctly and connected to an active
Ethernet, as discussed in the following sections.
Fiber-Optic Board LEDs and Connector Specifications
Table 3-1 describes the functions of these LEDs.
During normal operation, the link LED is on; the data LED blinks whenever the board is
receiving traffic.
Copper Board LEDs
The copper Gigabit Ethernet board has three LEDs per ports. Table 3-2 describes the
functions of these LEDs.

Components Purpose
LEDs One LED per port
Link/Activity: Turns on link, blinks on activity (green)
LEDs are located on the Fiber-Optic board visible through holes in the
metal bracket holder.
Connectors small form factor (SFF) LC
