The model
We buy, sell and trade hardware
We buy and sell tested Juniper, Arista, Brocade, and Cisco hardware. The same bench that grades equipment for our buyers evaluates the equipment we buy from our sellers, so every grade has to stand up on both sides of the transaction.
The bench
We don't take a supplier's word for it. We test it ourselves.
Every unit goes to our own certified technicians before it reaches the shelf: powered up, ports exercised, PSUs, fans and thermals checked, then verified again before it ships. Not a drop-ship, not a photograph of someone else's stock.
The desk
A person who knows the hardware
Quotes are answered by someone who can tell you what an EX4600-40F-AFI is without looking it up, and who will say so when a part is the wrong one for the job, usually the same business day.
Questions buyers ask
- Is the hardware tested before it ships?
- Yes. Every unit (new-excess, used, or refurbished) is bench-tested in-house by certified technicians before it is listed, and re-verified before it ships. See our Testing Process page for the details.
- How fast do orders ship?
- Orders placed by 12pm ship the same business day. Overnight shipping is available across the US, and we deliver worldwide.
- Do you buy used equipment?
- Yes. Buying and liquidating surplus gear is half our business. We buy Juniper, Arista, Brocade and Cisco hardware for cash, wire, or trade-in credit, arrange pickup, and process within 48 hours of receipt.
- How do quotes work for unpriced items?
- High-ticket and bulk items are quote-driven. Send the part number and quantity through the quote form, chat, or phone and a human who knows the hardware will come back with a firm price, typically the same business day.
