Secondary network interface
The IO Controller hub contains an Ethernet controller. An external physical layer
component provides the media interface to support 10/100 MB/s Ethernet. The Ethernet
controller supports:
•
Wake On LAN (WOL).
•
Deep power down mode.
•
Network boot.
For connector details, see page
.
The APOLLO V2Ix board has the capability to enable/disable the secondary Ethernet
port.
Two LEDs on each RJ-45 port provide information about its operation, as follows:
•
The LED on the left (as you look at the connector) tells you about the speed the port
is currently operating at.
•
The LED on the right (as you look at the connector) tells you whether the connector
is currently linked to the network, and indicates when activity takes place via that link,
i.e. when data is passing through.
The information provided by each LED is explained in the following table:
Ethernet port
Left LED (speed)
Right LED (link/activity)
10/100
Green: 100Mb/s
Off: 10Mb/s
Yellow: Link connected
Flashes: Activity is taking place
10/100/1000
Orange: 1000Mb/s
Green: 100Mb/s
Off: 10Mb/s
Yellow: Link connected
Flashes: Activity is taking place
Network boot
The Primary and Secondary Ethernet controllers both provide support for Preboot
Execution Environment (PXE) that allows for such features as remote booting and
loading of an operating system over a network. This support is provided using the Intel
Boot Agent Option ROMs and is configured via the BIOS setup screens – see
, page
, for further information.
Ethernet cables
To provide the best immunity to external interference a shielded twisted pair cable is
recommended for use with the APOLLO board. For Gigabit Ethernet this should be rated
as a CAT5E or higher cable.
