Universal Edge Router Fan Trays and
Power Supplies
April 2010
Part Number: 530-035370
Revision 01
This document describes the necessary steps to be taken to upgrade any MX series
chassis to higher capacity cooling and higher capacity power. Step by step descriptions
are given for replacement of the various parts in the chassis. All of these upgrades
can be performed while the system is operational, but it is important to follow the
complete process through.
NOTE: Combinations of regular-capacity and high-capacity supplies and fantrays are
not supported outside of the upgrade window.
NOTE: Before upgrading, the MX Series router ust 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.
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 platform.
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)
