What you get ordering this from us
Ordered by part number
The order is placed against PWR-2421-HV-RED, not against a description of it, so there is no room for a substitution you did not agree to.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
Is PWR-2421-HV-RED genuine and is the warranty intact?
Yes. It ships new in Arista packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will PWR-2421-HV-RED work in my server?
Send the server model and the part number of the supply already fitted. In a redundant pair both units have to match on wattage and efficiency grade, or the chassis alerts on every boot.
Do you accept purchase orders and quote at volume?
Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

Specifying a system, not just the part?
An accelerated node draws far more than a general-purpose server, so power is sized with the build rather than assumed from the chassis.
