MX104 3D Universal Edge Router Overview
The Juniper Networks MX104 3D Universal Edge Router is optimized for aggregating
mobile, enterprise WAN, business, and residential access services. The MX104 router is
designed for high-density access and pre-aggregation and is environmentally hardened
to allow outside deployments in cabinets and remote terminals. The router is a
high-performance router functioning as a universal aggregation platform for mobile
broadband and metro Ethernet applications. It also acts as a universal edge platform
supporting all types of private WAN, data center interconnect, Internet edge, business
edge, and residential edge services.
The router is powered by the Junos Trio chipset and runs the Junos®operating system
(Junos OS) for high-performance routing and switching. For a list of related Junos OS
documentation, see http://www.juniper.net/techpubs/software/junos/.
The chassis is a rigid sheet metal structure that houses all the other router components
(see Figure 1 on page 4 and Figure 2 on page 4). The hardware system provides resiliency
and redundancy, including power supplies and Routing Engines. The chassis also has
four built-in 10-Gigabit Ethernet SFP+ ports and four slots that accept Modular Interface
Cards (MICs). For a list of the supported MICs, see the MX Series Interface Module Reference.
The router is environmentally hardened and is 3.5 rack units (U; that is, 6.125 in., or 15.55
cm) tall. Several routers can be stacked in a single floor-to-ceiling rack, for increased
port density per unit of floor space. The chassis is installed in standard 11.81 in. (30
cm)-deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame
racks.
