Gigabit Ethernet Interface
The CP3003-HDD extension module includes one 10Base-T/100Base-TX/1000Base-T Ethernet
port based on one Intel® 82574L Gigabit Ethernet controller, which is connected to the x1 PCI
Express interfaces of the CP3003-SA’s Intel® QM77 Express Chipset.
The Intel® 82574L Gigabit Ethernet Controller’s architecture is optimized to deliver high per-
formance with the lowest power consumption. The controller's architecture includes indepen-
dent transmit and receive queues and a PCI Express interface that maximizes the use of bursts
for efficient bus usage.
The Boot-from-LAN is supported. After an operating system shutdown, a 1000Base-T Gigabit
connection is automatically reduced to 100 Mbit or 10 Mbit operation and the Ethernet control-
ler waits to receive a broadcast or unicast packet with an explicit data pattern to assert a signal
or a PME message to wake up the system.
The Gigabit Ethernet interface is implemented as an RJ-45 connector, J5 (GbE C), with inte-
grated magnetics and supplies the 10Base-T, 100Base-TX and 1000Base-T interfaces to the
Ethernet controller.
Ethernet LED Status
ACT (green):
This LED monitors network connection and activity. The LED lights up when a
valid link (cable connection) has been established. The LED goes temporarily off if network
packets are being sent or received through the RJ-45 port. When this LED remains off, a valid
link has not been established due to a missing or a faulty cable connection.
SPEED (green/orange/off):
This LED lights up to indicate a successful 100Base-TX or
1000BASE-T connection. When green it indicates a 100Base-TX connection and when orange
it indicates a 1000Base-T connection. When not lit and the ACT-LED is active, the connection
is operating at 10Base-T.
Note ...
The Ethernet transmission can operate effectively using a CAT5 cable with a
maximum length of 100 m.
