What you get ordering this from us
Ordered by part number
ER-X-US is what is quoted and ER-X-US is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
- Is ER-X-US 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 ER-X-US 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.
