Hard Drive Activity LED Header | Intel D945GCLF2 specs

Intel Desktop Board D945GCLF2 Technical Product Specification

2.2.2.4.1Hard Drive Activity LED Header

Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is being read from or written to a hard drive. Proper LED function requires one of the following:

•A Serial ATA hard drive connected to an onboard Serial ATA connector

•A Parallel ATA IDE hard drive connected to an onboard Parallel ATA IDE connector

2.2.2.4.2Reset Switch Header

Pins 5 and 7 can be connected to a momentary single pole, single throw (SPST) type switch that is normally open. When the switch is closed, the board resets and runs the POST.

2.2.2.4.3Power/Sleep LED Header

Pins 2 and 4 can be connected to a one- or two-color LED. Table 19 shows the possible states for a one-color LED. Table 20 shows the possible states for a two-color LED.

NOTE

The colors listed in Table 19 and Table 20 are suggested colors only. Actual LED colors are chassis-specific.

2.2.2.4.4Power Switch Header

Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The switch must pull the SW_ON# pin to ground for at least 50 ms to signal the power supply to switch on or off. (The time requirement is due to internal debounce circuitry on the board.) At least two seconds must pass before the power supply will recognize another on/off signal.

D945GCLF2 specifications

The Intel D945GCLF2 is a compact and efficient motherboard designed for the Intel Atom processor family, particularly suited for low-power, cost-sensitive systems. This mini-ITX form factor board was released as a part of Intel's D945 series, targeting small form factor PCs, embedded systems, and home theater PC (HTPC) builds.

One of the standout features of the D945GCLF2 is its support for the Intel Atom N270 processor, a dual-core CPU that operates at a low thermal design power (TDP) of just 4 watts. This makes the board ideal for users looking to build energy-efficient systems without compromising on performance. The motherboard supports up to 2GB of DDR2 RAM, utilizing a single-channel memory architecture, which, while modest by today’s standards, suffices for basic computing tasks such as browsing, document editing, and media playback.

In terms of connectivity, the D945GCLF2 integrates a variety of I/O ports that enhance usability. It features four USB 2.0 ports, one PCI slot, and an IDE connector, catering to older peripherals while also allowing for the installation of additional components like graphics cards and network adapters. The onboard Intel Graphics Media Accelerator 950 provides adequate graphics performance for everyday activities and even supports HD video playback, making it a solid choice for multimedia applications.

Incorporating Intel's Advanced Configuration and Power Interface (ACPI) technology, the D945GCLF2 allows for efficient power management, giving users the flexibility to optimize their system's energy consumption. The board also includes essential connectivity options such as Ethernet through a 10/100 LAN port, facilitating wired networking capabilities.

Furthermore, the D945GCLF2 is equipped with multiple storage options; it provides support for Serial ATA (SATA) devices, allowing for faster data transfer rates compared to traditional PATA drives. The BIOS is user-friendly and offers a range of settings for users looking to tweak their system's performance.

Overall, the Intel D945GCLF2 motherboard is a robust solution for anyone looking to build a low-cost, low-power computing system. Its combination of small form factor, energy efficiency, and decent performance makes it suitable for a variety of applications, from basic user tasks to serving as the core of a compact home theater setup. Despite its age, the D945GCLF2 remains relevant for specific, budget-friendly builds, showcasing Intel's legacy in innovative motherboard design.
