Fan Header

This motherboard has one GPU fan header (GPU_Fan1). This 4-pin fans header is backward compatible with 3-pin fans. However, fan speed control is available for 4-pin fans only. The fan speeds are controlled by firmware thermal management via IPMI 2.0.. See the table on the right for pin definitions

LAN1/2/3/4 (Ethernet Ports)

Up to four Gigabit Ethernet ports (designated LAN1, LAN2, LAN3 and LAN4) are located on the rear of the serverboard. The H8DCT-HIBQF has two ports whereas the H8DCT-HLN4F has four. Additionally, there is a dedicated LAN for IPMI next to the four rear LAN ports. These Ethernet ports accept RJ45 type cables.

Unit Identifier Button

In addition to the UID (Unit Identifier) button on the rear I/O panel, there is another UID button located on the control panel. When you push either UID button, both Rear UID and Front Panel UID Indicators will illuminate. Push either button again to turn off both indicators. These UID indicators provide easy identification of a system unit that may be in need of service.
