What Happens During Card Initialization
Sequence?
Following is an overview of the initialization sequence for the PCI
10/100Base-TX and (for V-Class servers) the 100Base-FX cards.
Initialization of a PCI 10/100Base-TX or 100Base-FX card happens
during system bootup only, and it is driven by the btlan driver for the
card. Whenever initialization fails, it prints a message on the console
identifying the failure. You can later retrieve initialization messages
after the system is fully booted up by using the dmesg command. Finally,
the driver tries to establish a good data link between the card and the
hub or switch.
The Link Status LED is for the RJ-45 connector only. The link LED is lit
only when the RJ-45 connector on the card is connected properly to a
10/100 Mbit/s switch or hub.When the RJ-45 cable connection is used,
the link LED must be lit to indicate proper functioning. If there is no
RJ-45 cable connection, or if the cable connection is bad, or if the hub or
switch is not compatible, that is, not 10Base-T or 100Base-TX capable, no
LEDS will be lit. Also, a message indicating the detection of a bad cable
connection is printed on the console as well as logged in NETTL logs.
The Link LED functions as follows:
• LED solid green = link established in 100Base-TX mode.
• LED solid yellow = link established in 10Base-T mode.
• LED remains dark in 10Base2 (BNC) or 10Base5 (AUI) mode. The
Status LED is dark if the AUI or BNC port is used.
The Activity LED flashes whenever the switch is sending link pulses. If
the activity LED on the card is not blinking, then there may be a problem
with the driver or the card. Contact HP.
NOTE The RJ-45 connection operates at either 10 or 100 Mbits/s, but the BNC
and AUI connections operate only at 10 Mbits/s.
