10GbE Network Upgrade Module

The Synology E10G22-T1-Mini adds a 10GbE RJ-45 port to compatible compact Synology servers through a dedicated network upgrade slot. It supports IEEE 802.3an 10GBASE-T, NBASE-T 2.5/5GbE, and backwards-compatible 1GbE and 100MbE standards. Auto-negotiation selects the highest available speed automatically. The module operates from 0°C to 40°C.

Suited for multi-gigabit LAN environments

Editors and small teams moving large media files or running concurrent backups benefit from the 10Gbps link and 9KB jumbo frames. Offload features such as TCP/UDP/IP checksum, TSO, LSO, RSS, GRO and GSO reduce host CPU load during sustained transfers. Buyers whose Synology unit lacks the dedicated Network Upgrade Slot cannot use this module and must seek alternative connectivity.

Requires a dedicated Network Upgrade Slot

Compatibility is limited to Synology models equipped with the specific internal slot for this form factor. The module measures 1.04" x 1.79" x 2.98" and draws power directly from the slot. No other interface or adapter is supported. Verify the slot exists on the target server before purchase.

Questions about this item

How do I install the E10G22-T1-Mini in the dedicated network upgrade slot?

Power off the compatible Synology server, open the chassis cover, align the module with the dedicated network upgrade slot, press firmly until seated, replace the cover, and power on; the step often missed is fully powering down before insertion to avoid detection issues

What maintenance or replacement will the E10G22-T1-Mini need over time?

No scheduled maintenance is required; keep the operating environment within 0°C to 40°C and 5% to 95% RH, ensure airflow around the 1.04" x 1.79" x 2.98" module remains unobstructed, and replace only if a port fails or network needs change

What limit appears first during sustained 10 Gbps transfers on the E10G22-T1-Mini?

The primary limit is the host system's PCIe lane allocation and CPU offload capacity — features such as TCP/UDP/IP checksum offloading, TSO, LSO, RSS, GRO and GSO reduce overhead, but sustained line-rate throughput depends on the server's internal bus and processing headroom
