Dual-port 10GbE network card with two RJ45 connectors

Synology Inc.

Synology Inc. E10G30-T2 dual-port 10GbE 10GBASE-T network card

SKU CH-RD1Y-B59A8 MPN E10G30-T2

Dual-port 10GbE RJ45 adapter adds two 10 Gb/s links to compatible Synology systems via PCIe, supporting link aggregation up to 20 Gb/s with failover and CPU offloading

Model E10G30-T2

  • Dual 10GbE ports deliver up to 20 Gb/s aggregated throughput
  • Link Aggregation Group support enables load balancing and port failover
  • CPU offloading capabilities maintain optimal system performance
  • Familiar RJ45 connectors ensure backwards compatibility with existing networks
  • PCIe add-in card designed for Synology system integration

Dual 10 GbE RJ45 adapter

This dual-port 10GBASE-T add-in card uses a PCIe 3.0 x8 interface and familiar RJ45 connectors that work with existing copper cabling. It is designed for Synology systems that need faster wired throughput than 1 GbE can provide. Each port runs at up to 10 Gb/s over standard Cat 6a or better cable.

Suited for NAS upgrades, not new builds

The card targets owners of compatible Synology units who want to add or expand 10 GbE connectivity without replacing their switch infrastructure. It is not intended for generic PC builds, laptops or equipment that lacks a PCIe x8 slot and Synology firmware support.

PCIe 3.0 x8 slot required

Installation needs a free PCI Express 3.0 x8 lane; the card will not fit or function in x4, x1 or older PCIe generations. Verify that your Synology model lists this part as supported before purchase.

Questions about this item

Does the Synology E10G30-T2 include cables or brackets, or must they be purchased separately?

The card uses standard RJ45 connectors compatible with existing Cat6a or better Ethernet cables; no proprietary cables or brackets are mentioned in the specifications.

When should I choose the dual-port E10G30-T2 over a single-port 10GbE card?

Choose the dual-port model when you need link aggregation for up to 20 Gb/s throughput, port failover redundancy, or load balancing across two connections.

What does the 10GBASE-T rating mean for actual transfer speeds inside a Synology NAS?

Each port supports up to 10 Gb/s over copper cabling; with link aggregation the two ports can combine for up to 20 Gb/s while CPU offloading keeps system overhead low.
