MX204 Chassis Description
The router chassis is a rigid sheet metal structure that houses all the other router components.
Figure 2 on page 23 shows the front of the fully configured chassis. The chassis measures 1.72 in. (4.37 cm)
high, 19 in. (48.26 cm) wide, and 18.5 in. (47.0 cm) deep. You can install the router chassis in standard
760-mm deep (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks. The total
weight of fully loaded router is 22.7 lb (10.3 kg). For more information, see “MX204 Router Physical
Specifications” on page 55.

The MX204 has four rate-selectable ports that can be configured as 100-Gigabit Ethernet ports or 40-Gigabit
Ethernet ports, or each port can be configured 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.
Starting in Junos OS Release 18.3R1, you can use the Mellanox 10-Gbps pluggable adapter (QSFP+ to
SFP+ adapter or QSA; model number: MAM1Q00A-QSA) to convert four lane-based ports to a single
lane-based SFP+ port. The QSA adapter has the QSFP+ form factor with a receptacle for the SFP+ module.
Use the QSA adapter to convert a 40-Gbps port to a 10-Gbps or a 1-Gbps port.
