An expansion shelf has to be supported by the head unit's firmware, not merely cabled to it. Tell us the controller and we will confirm the shelf is on its supported list.

What you get ordering this from us
Ordered by part number
QXP-1620S-B3616W is what is quoted and QXP-1620S-B3616W is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Supported by the head unit
We confirm the shelf is on the controller’s supported list, not merely that the cable fits.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
- Is QXP-1620S-B3616W 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 QXP-1620S-B3616W 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.
