Questions about this item

Will the two 10GbE RJ-45 ports on the RS3626xs connect directly to my existing 1GbE switch?

Yes, the 10GbE ports auto-negotiate down to 1GbE, so they link to older switches without extra adapters.

Which LEDs on the front panel confirm the RS3626xs is operating normally after power-on?

The Power LED stays solid green, each drive LED shows steady or blinking green for healthy RAID activity, and both 10GbE LAN LEDs light green when linked.

Does the RS3626xs shipment include the twelve 4TB enterprise drives and the 800GB cache modules pre-installed?

Yes, the box contains the main unit with twelve 4TB Synology Enterprise NAS drives and two 400GB Synology Enterprise Cache modules already fitted, plus two C13-to-C14 power cords, a front cover and the accessory pack.
