This document describes the necessary steps to be taken to upgrade any Juniper Networks
MX Series 3D Universal Edge Router 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 fan
trays are not supported outside of the upgrade window.
CAUTION: The router cannot be powered from AC and DC power supplies
simultaneously. The first type of power supply detected by the router when
initially powered on determines the type of power supply allowed by the
router. All installed power supplies of the other type are disabled by the router.
If you install a power supply of the other type while the router is operating,
the router disables the power supply and generates an alarm.
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.

    CAUTION: Always keep the air filter in place while the router is operating, except during replacement. Because the fans are very powerful, they could pull small bits of wire or other materials into the router through the unfiltered air intake. This could damage the router components.
