Intel ISP1100 Scsi Hard Drive LED Connector, Intel Pro/100+ Server 82559 Ethernet Controllers

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.
