Is S4128F-ON genuine and is the warranty intact?

Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.

Will S4128F-ON work in my server?

Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.

Do you accept purchase orders and quote at volume?

Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Product overview

S4128F-ON is a Dell 28x10G SFP+ 2x100G QSFP28 tor. Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. Tell us both switch models and we will confirm compatibility before it ships.

We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.
