The Juniper Networks MX204 Universal Roung Plaorm is an Ethernet-opmized edge router with
400-Gbps capacity that provides both switching and carrier-class Ethernet roung. The MX204 router
runs Junos operang system (Junos OS), enabling a wide range of business and residenal applicaons
and services, including high-speed transport and virtual private network (VPN) services, next-generaon
broadband mulplay services, and high-volume Internet data center internetworking. Each router
provides full duplex, high-density Ethernet interfaces and high-capacity switching throughput and uses
the Junos Trio chipset for increased scalability of Layer 2 and Layer 3 packet forwarding, buering, and
queuing.
The MX204 router is compact and one rack unit (1 U) tall. Several routers can be stacked in a single
oor-to-ceiling rack for increased port density per unit of oor space.
The MX204 router is a xed-conguraon router, and supports one built-in Roung Engine. The router
runs on AC or DC power, with two dedicated power supply modules on each device. Cooling is handled
by three fan modules.
The MX204 has four rate-selectable ports that can be congured as 100-Gigabit Ethernet ports or 40-
Gigabit Ethernet ports, or each port can be congured as four 10-Gigabit Ethernet ports (by using a
breakout cable). The MX204 also has eight 10-Gigabit Ethernet ports. The four rate-selectable ports
support QSFP28 and QSFP+ transceivers, whereas the eight 10-Gigabit Ethernet ports support SFP+
transceivers.
