Product overview
Part number 845398-B21 identifies this HPE / HP HPE 25Gb SFP28 SR 100m Transceiver Module (for FlexFabric 25GbE adapters, e.g. 640FLR-SFP28). Reach, fibre type and connector have to agree along the whole path, and a patch panel in the middle counts. Send the run length and the fibre already installed and we will match it.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Questions buyers ask about this part
- Is 845398-B21 genuine and is the warranty intact?
- Yes. It ships new in HPE / HP 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 845398-B21 work in my server?
- Tell us the switch at both ends of the link. Optics are frequently vendor-coded, so a module that is electrically correct can still refuse to come up; we confirm the coding for both ends before it ships.
- 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?
Optics and cabling are part of the fabric spec on a cluster build — both ends and the switch have to agree.
