Juniper EX4400 - Page 17

• PoE models (EX4400-24P, EX4400-24MP, EX4400-48P, and EX4400-48MP) support IEEE 802.3bt
Power over Ethernet (PoE-bt), fast Power over Ethernet (PoE), and Perpetual PoE
• Hot-swappable AC or DC power supplies. We ship EX4400 switches with one AC or DC power
supply. Order an addional power supply and power cord separately if you need 1+1 redundancy.
For more informaon about the EX4400 power system, see EX4400 Power System
• Dual hot-swappable fan trays that provide front-to-back or back-to-front airow. For informaon
about the cooling system and airow in EX4400, see Cooling System and Airow in an EX4400
Switch
• A slot to install an oponal extension module. See "Extension Modules in EX4400 Switches" on page

Benets of the EX4400 Switch
Cloud readiness—EX4400 switches are our rst cloud-ready switches. You can deploy the switches and
manage them by using Juniper Mist.
Support for Virtual Chassis—EX4400 switches support Virtual Chassis technology. You can interconnect
up to 10 EX4400 switches to form a Virtual Chassis.
Support for channelizaon—You can channelize the QSFP28 ports on the EX4400 switch and increase
the number of interfaces.
Support for MACsec and EVPN-VXLAN architecture—EX4400 switches support IEEE 802.1AE Media
Access Control Security (MACsec) and EVPN-VXLAN. Support for MACsec and EVPN-VXLAN ensures
link-layer data condenality, data integrity, and data origin authencaon to help secure deployments
in enterprise mulcloud deployments. On the EX4400 switches, the MACsec AES-256 encrypon
capability is supported on all RJ-45, SFP, and SFP+ network ports. MACsec AES-256 is supported on the
SFP28 ports of the 25GbE (EX4400-EM-4Y) and the QSFP28 ports of the 100GbE (EX4400-EM-1C)
extension modules. EX4400-24X supports MACsec AES-256 on the nave front-panel 100GbE ports as
well.
