Product overview
3873IR1 is a Lenovo B6510 24x16G fibre channel SFP SAN Switch. Switches are chosen on port mix and uplink capacity rather than headline throughput. This one is 24x16G. Tell us what it is aggregating and we will confirm the uplinks and optics you will also need.
Ask for the optics and rail kit on the same quote; a switch that arrives without them still cannot be racked.

What you get ordering this from us
Ordered by part number
3873IR1 is what is quoted and 3873IR1 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
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 3873IR1 genuine and is the warranty intact?
Yes, new and sealed, with the Lenovo warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 3873IR1 work in my server?
Tell us what it is aggregating and what optics you already hold. We confirm the port mix, the uplink capacity and the airflow variant, and we will list the optics and rail kit you will also need.
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.

Specifying a system, not just the part?
Multi-node training is bounded by the fabric between the nodes, so the switch is specified with the cluster rather than after it.
