Dual-port Gigabit server adapter

The Intel E1G42ETBLK is a PCI Express x4 network card that provides two RJ45 ports for 10/100/1000Base-T connectivity. It targets administrators who need to add redundant or aggregated wired links to a rack-mount or tower server. The low-profile and full-height brackets included allow installation in a variety of chassis depths.

Sustained throughput on two ports

Each port negotiates at 10, 100 or 1000 Mbps over Category 5 twisted-pair cable. The x4 host interface supplies enough bandwidth so that both ports can operate at line rate simultaneously without internal contention. Traffic is handled by the onboard controller rather than the system CPU, keeping latency predictable during long file transfers or backup windows.

Thermals noise and power in normal use

The plug-in card draws modest power from the PCI Express slot and requires no auxiliary connector. Passive cooling keeps the adapter silent in typical server airflow, and the lightweight 0.25 kg construction adds minimal stress to the motherboard slot. Heat output remains low enough for dense multi-card deployments.

Questions about this item

How much power does the E1G42ETBLK draw when running all day at 1000 Mbps?

The adapter uses a PCI Express x4 slot and operates at 10/100/1000 Mbps speeds. Typical server adapters of this class draw only a few watts under load, so heat and fan noise inside the chassis remain minimal.

What cable type and bracket style must I already have to install the E1G42ETBLK?

You need Category 5 twisted-pair cables with RJ45 plugs. The package includes both a low-profile and a full-height bracket, so either chassis style works without extra parts.

Will the E1G42ETBLK negotiate down to 10 Mbps on my older 10BASE-T switch?

Yes. The card supports 10BASE-T, 100BASE-T and 1000BASE-T, so it will automatically link at the highest speed the connected switch allows.
