The rating upgrade is needed to ensure the chassis rating is in line with the optional higher
capacity power supplies that may be installed in your MX Series router. The upgrade kit
contains the following items; they are also available as spares:
Up to four power supplies
Up to two fan trays
Optional one filter tray (MX960)
Rating label
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.
Cooling
Power
Rating label change
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 OS
Release 10.0 R1 or later to support high-capacity fan trays. Junos OS Release
10.0 R2 is required to support the MX240 and MX480 AC and DC high capacity
power supplies, and the MX960 AC high- capacity power supplies. Junos OS
Release 10.2 R1 is required to support the MX960 DC high-capacity power
supplies.
