Buying guide
Finding the right network part
Match the platform first
Line cards, uplink modules and power supplies are specific to a switch or router family. Start from the chassis or base model, then pick the module.
Optics follow the port
SFP, SFP+, SFP28, QSFP+ and QSFP28 ports each take their own transceivers, and some vendors only accept coded optics in their gear.
Licenses are separate
Firewall subscriptions, controller AP licenses and switch feature licenses are tied to the manufacturer's terms and often to a serial number. Check what transfers before buying.

Frequently asked questions
Do you carry end-of-life networking gear?
Yes. Alongside current platforms, the catalog lists HP ProCurve and 3Com switches and modules, older Juniper SSG and NetScreen appliances, and 56K and DSL modem cards for legacy systems.
Can I mix third-party transceivers with my switch?
Often, but not always. Some vendors only enable coded optics. Compatible transceivers coded for your switch brand avoid the issue.
What's the difference between a switch and a router?
A switch connects devices within a network and forwards traffic by MAC address, while a router moves traffic between networks by IP address. Layer 3 switches do some routing as well.
