Juniper EX4400 Ethernet Switch
According to Juniper, the EX4400 line of Ethernet switches is designed for access in enterprise campus, branch and data center networks. The EX4400-24X model can also be used as a distribution switch.
The line includes models with 1GbE copper ports, multigigabit ports up to 10GbE and SFP+/SFP fiber ports. PoE models provide IEEE 802.3bt PoE++ with up to 90 W per port and, depending on the model, a PoE budget of up to 3600 W. Two 100GbE ports serve as Virtual Chassis connections or uplinks, and up to ten switches are managed as a single device. Further features include EVPN-VXLAN, MACsec with AES256, redundant power supplies and cloud management with Juniper Mist Wired Assurance.
We are happy to advise you on project and volume enquiries. On request, DEVACON handles planning, configuration and commissioning.
