Upgrading MX240, MX480, and MX960 3D Universal Edge Router Power Supplies and Fan Trays
In this guide, three areas are addressed, and all three have to be completed before
your MX Series router is fully enabled for higher capacity power and cooling.
Higher capacity cooling is required for some types of DPCs or MPCs, and higher
capacity power is required for a higher number of newer MPCs. Note that there are
minimum software revision requirements for the cooling and power modules. Without
this minimum software revision, these new parts are not supported and likely not
detected and managed properly.
NOTE: Before upgrading, the MX Series router must be running JUNOS Release 10.0
R1 or later to support high-capacity fan trays and JUNOS Release 10.0 R2 to support
high-capacity power supplies.
