Description 17
For more details on programming and reading the Heceta 2 chip please refer to the Heceta 2 Device
Specification version 1.2 or later (see Chapter 13 in the Intel ISP1100 Internet Server Technical
Product Specification for how to obtain this specification).
SCSI Hard Drive LED Connector
The optional SCSI hard drive LED connector is a 1 x 2-pin connector that allows add-in SCSI
controller applications to use the same LED as the IDE controller. This connector can be connected
to the LED output of the add-in controller card (see Chapter 13 in the Intel ISP1100 Internet Server
Technical Product Specification for the location and pinouts of the SCSI hard drive LED
connector).
Intel® Pro/100+ Server (82559) Ethernet Controllers
Two Intel Pro/100+ Server (82559) Ethernet controllers provide two 10/100 Base-T interfaces
accessible from the back panel (see Chapter 13 in the Intel ISP1100 Internet Server Technical
Product Specification for the location and pinouts of the LAN connectors).
The LAN connectors on the back panel do not provide LEDs to indicate transmit/receive activity
and speed. Instead, these indicators are routed to four LEDs on the front panel. See “Controls,
Connectors, and Indicators” for LED locations and definitions.
Alert on LAN and Wake on LAN features are supported by the TR440BX server board software
and the SMBUS interface of the Intel 82559s. See the BIOS specification for information
regarding Alert on LAN and Wake on LAN. Also see “Wake on LAN” for more information.
CAUTION
For Wake on LAN, the 5V standby line for the power supply must be capable
of delivering +5V ±5% at 720 mA. Failure to provide adequate standby
current, when implementing Wake on LAN can damage the power supply.
Wake on LAN
Wake on LAN enables remote wakeup of the computer through a network. If a PCI add-in network
interface card (NIC) with remote wakeup capabilities is desired, the remote wakeup connector on
the NIC must be connected to the onboard Wake on LAN connector.
The integrated LAN controllers or the add-in NIC monitors network traffic at the MII interface.
Upon detecting a Magic Packet, the LAN controllers or NIC assert a wakeup signal that powers up
the computer.
To access this feature, use the optional Wake on LAN connector on the server board. See “Server
Board Connectors and Components” for the location and definition of the Wake on LAN connector.
