MX150 Router Overview
The MX150 Universal Routing Platform is a compact, high-performance edge router that
is ideally suited for lower bandwidth service provider applications and distributed service
architectures, and for enterprise WAN use-cases. MX150 offers 40 Gbps of throughput
in a single rack-unit, while providing advanced services with high performance. The MX150
supports advanced technologies like telemetry that simplify your operations environment,
and maximize network uptime.
The MX150 is 1 rack unit (U) tall. The MX150 can be mounted on a desk or any other level
surface, on two posts in a Rack, and on four pots in a rack or Cabinet. The MX150 conserves
space and contains costs associated with power and cooling.
