Extreme ExtremeSwitching SLX 9250 Switches - Refurbished, Used, New

Best Selling

Extreme ExtremeSwitching SLX 9250 switches are 1RU 100G spine and aggregation switches with 32 QSFP28 ports, built for leaf-spine data center fabrics and high-capacity enterprise cores. Each QSFP28 port runs at 100G or 40G, and supported ports break out to multiple 25G or 10G links, so one chassis can aggregate a mix of leaf switches, servers and uplinks. The SLX 9250 runs Extreme's SLX-OS with Layer 2 and Layer 3 switching, IPv4 and IPv6 routing, and streaming telemetry. NetworkTigers sells SLX 9250 chassis, power supplies and fan modules refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which SLX 9250 do I need?

Start with airflow. The SLX 9250 comes in F (front-to-back) and R (back-to-front) versions, and which one you need depends on whether the ports face the hot aisle or the cold aisle in your rack. Decide where the cold air comes from, then pick the version whose intake is on that side; each listing states the airflow direction of the unit. Fans and power supplies must all move air in the same direction as the chassis, so when you buy a bare SLX9250-32C, order power supplies and fans of the same airflow. Then choose AC or DC input to match your rack power, and decide how many of the 32 ports you will run at 100G, at 40G, or broken out to 25G or 10G, since that sets the optics and cables you need. Tell us the version of SLX-OS you run and we will confirm the hardware matches.

Frequently asked questions

Does the SLX 9250 work as a leaf as well as a spine?
Yes. With 32 QSFP28 ports it is most often a spine, but broken out to 25G or 10G it serves as a high-density leaf for servers or storage, with the remaining 100G ports used as uplinks.

Can a bare chassis be bought without power supplies and fans?
Yes. Some listings are the chassis alone and others ship complete. Each listing states what is installed, and we can add matching power supplies and fans to an order so the unit arrives ready to rack.

What should be in the box for a refurbished SLX 9250?
The chassis, any power supplies and fans named in the listing, and rack ears. Power cords, optics and cables are listed separately unless stated otherwise.
