The Intel PRO 1000 MT Quad Port Server NIC Card is a PCI-X network card for server applications, supporting four network ports with data rates of 10, 100, and 1000 Mbps per port. The product is specifically designed for use in servers requiring high network bandwidth and simultaneous connection of multiple network interfaces. The card is based on the Intel® 82546EB controller and is designed for 3.3-volt PCI-X slots, supporting both 32- and 64-bit bus widths. Bus speeds include 33, 66, 100, and 133 MHz, enabling flexible integration into various server platforms.

Applications
This network card is suitable for server environments requiring high network throughput and simultaneous connection to multiple networks. It is typically used in data centres, enterprise servers, or systems with high demands for network availability and performance. The support for 10/100/1000 Mbps per port enables a scalable network architecture, and the card is also suitable for applications with high data rates.

Features and Specifications in Detail
The card features an integrated packet buffer in the Media Access Controller with a capacity of 256 KB (64K x 4), ensuring efficient processing of network data packets. Additionally, a 10 KB PCI-X bus buffer memory is integrated into the bridge chip, optimising data transfer between the card and the system bus. A 256 KB flash memory is provided for storing the Intel® Boot Agent, supporting network boot functions. The card supports the IEEE standard 802.3ab, which defines Gigabit Ethernet transmission over copper cables.

Technology Explained Simply
The network card operates in Bus Master DMA mode, meaning it transfers data directly between the network and memory without requiring active involvement of the main processor. This increases efficiency and reduces CPU utilisation. Power is supplied via the 3.3-volt PCI-X slot, with a typical power consumption of 16.8 watts. The card is designed for operating temperatures from 0 to 55 °C and can operate at a relative humidity of up to 85 % at 55 °C. The MTBF (Mean Time Between Failures) is 58.15 years, indicating high reliability.

Compatibility and Accessories
The card is designed for 3.3-volt PCI-X slots and supports both 32- and 64-bit bus widths. Bus speeds of 33, 66, 100, and 133 MHz allow use in various server platforms. The card complies with hardware certifications FCC Class A, CE, GOST, AS/NZ 3548, BSMI, ICES-003, and VCCI, confirming compliance with international electromagnetic compatibility and safety standards.

Installation and Mounting
The card is installed into a free PCI-X slot in the server. Physical dimensions are 16.5 cm in length and 10.7 cm in width. Installation requires no additional components, as the card is fully equipped with integrated functions and memory. Interrupt levels INTA, INTB, INTC, and INTD enable communication with the system bus.

Operational Advantages
The card offers high network throughput with four independent 10/100/1000 Mbps ports, enabling simultaneous connection to multiple networks. Bus Master DMA technology reduces CPU utilisation and improves system efficiency. The high MTBF and support for standards such as IEEE 802.3ab ensure a reliable and standards-compliant network connection. The card is suitable for use in servers with high demands for network performance and availability.
