Is 10 GE fully compatible with 1 GE?

Hi Experts,

I'm planning to purchase a server with 10 GE NICs.

Will it work in 1 GE environment without any problems? (all switches, servers are running 1 GE on Cat 5e at the moment)

Thank you!

Depends on the card PHY (or sfp module) installed
It may take couple of rounds of netcard and switch firmware service to get them autonegotiate.

A 10Gbps copper NIC should fall-back to 1Gbps if the driver supports it.

it should sync at 1G speed as far as I know.
