The Juniper EX2200 series switch, a fixed-configuration, low-cost Layer 2/Layer 3 access switch, has reached its End-of-Life (EOL) and End-of-Engineering (EOE) milestones. This paper details the technical and procedural steps required to obtain the final firmware releases (Junos OS) for these devices.

Special attention is given to legal and contractual requirements due to the device’s legacy status.
