Juniper MX240 - UPGRADING User Manual

Fan Tray Upgrade Overview
The MX Series high-capacity fan trays satisfy cooling requirements for high-density DPCs
and MPCs, and must be upgraded for proper cooling (see Figure 1 on page 4, Figure 2
on page 4, and Figure 3 on page 5). Additionally, for the MX960 router, you must
upgrade both fan trays and the filter tray.
NOTE: Before upgrading, the MX Series router must be running Junos OS
Release 10.0 R1 or later to support high-capacity fan trays.
NOTE: To prevent overheating, install the replacement fan tray immediately
after removing the existing fan tray.
