Frequently Asked Questions

What is the difference between Juniper EX and QFX switches?

EX Series switches are designed for campus networks — access layers, distribution, and wired/wireless convergence. They run Junos OS with features like Virtual Chassis stacking, 802.1X authentication, and MACsec encryption. QFX Series switches are built for data center fabrics — high-bandwidth spine-leaf topologies at 10/25/40/100GbE with EVPN-VXLAN support. Choose EX for campus and branch deployments. Choose QFX for data center core, leaf, and spine roles.

Does refurbished Juniper equipment run the latest Junos OS?

Yes. Junos OS is a software feature — refurbished hardware runs the same Junos release as new devices. Enterasource tests all switches with current Junos firmware and resets configurations to factory defaults before shipping. Software maintenance contracts for ongoing Junos updates and TAC support can be purchased separately through Juniper.

What Juniper firewalls does Enterasource carry?

Enterasource stocks Juniper SRX Series next-generation firewalls including the SRX300 Series for branch office security and the SRX1500, SRX4100, and SRX4200 for mid-range and data center deployments. SRX firewalls run Junos OS with integrated IPS, application visibility, and IPsec VPN. All SRX devices are fully tested before shipping.
