3: Operating the Gigabit Ethernet Card

Using LEDs to Determine Card Functionality

The copper Gigabit Ethernet cards have light-emitting diodes (LEDs) that indicate

whether the card is conﬁgured correctly and connected to an active Ethernet, as

discussed in the following sections.

The copper Gigabit Ethernet card has three LEDs per ports. Table 3-1 describes the

functions of these LEDs.

Verifying Card Recognition

To verify that the operating system has located the Gigabit Ethernet card, use the Linux

PCI utilities lspci(8) command, as follows:

# lspci -d 14e4:

0b:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

0b:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

0c:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

0c:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

In 0b:00.0 Ethernet controller identification, 0b is the bus number, 00 is the

slot number, and 0 is the port, respectively.
