Juniper EX Series switches: Engineering & Decommissioning
Prepare and deploy Juniper EX switching with the right configuration, physical connectivity and acceptance checks. Compritech supports switch refreshes, Virtual Chassis work and the controlled retirement of existing campus infrastructure.
Juniper EX services
Commission & validate
Check access ports, uplinks, optics, VLAN reachability and the agreed Layer 3 functions. Validate Virtual Chassis membership and failover where the design uses those features.
Refresh & retire
Map uplink and endpoint dependencies before removing a member or replacing a switch. Retire configurations and storage using the agreed device-specific process.
