10Gbps Dual-Port Server Adapter

The ASUS PEB-10G/57840-2T is a plug-in network card designed for servers and workstations that require wired 10Gbps Ethernet connectivity. It installs into an available PCI Express 3.0 x8 slot and presents a single RJ45 connector for copper cabling. This adapter targets IT professionals upgrading existing rackmount or tower systems.

PCI Express 3.0 x8 interface requirement

The card operates over a PCI Express 3.0 x8 electrical connection, so the host system must provide a compatible slot with sufficient lane allocation. Verify that the motherboard or riser can deliver x8 bandwidth; an x4 or x1 slot will limit throughput or prevent operation. No other bus standard or connector type is supported by this hardware.

Suits copper-based 10GbE deployments

This adapter suits administrators deploying 10Gbps links over existing Cat6a or Cat7 copper infrastructure where SFP+ fibre modules are not required. It is not for environments needing multiple physical ports beyond the single RJ45 provided, nor for systems lacking a full-size PCIe 3.0 x8 slot. Buyers requiring fibre connectivity or additional ports should consider alternative models.

Questions about this item

What does the 10Gbps rating mean for actual file transfers?

Each port can move up to ten gigabits per second, so large sequential reads and writes run near wire speed on a matching switch and cabling.

What does the PCIe 3.0 x8 interface limit in practice?

The eight-lane Gen 3 link provides enough bandwidth for both 10Gbps ports simultaneously without saturating the bus.

What slot and bracket space does the card need to install?

It requires a PCI Express x8 or wider slot and one rear-panel opening for its RJ45 connector.
