Verifying The Extended Cable Manager Is Correctly Installed - Juniper MX960 Hardware Manual

6. For an AC-powered router, switch the AC switch in the chassis above each power supply to the on
position (—) and observe the status LEDs on each power supply faceplate. If an AC power supply is
correctly installed and functioning normally, AC OK and DC OK LEDs light steadily, and the PS FAIL
LED is not lit.
For a DC-powered router, switch the circuit breaker on each of the power supplies to the ON position
and observe the status LEDs on each power supply faceplate. If a DC power supply is correctly installed
and functioning normally, PWR OK, BREAKER ON, and INPUT OK LEDs light steadily.
If any of the status LEDs indicates the power supply is not functioning normally, repeat the installation
and cabling procedures described in the
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back
on. After powering on a power supply, wait at least 60 seconds before turning it off.
If the system is completely powered off when you power on the power supply, the Routing
Engine boots as the power supply completes its startup sequence.
After a power supply is powered on, it can take up to 60 seconds for status indicators—such
as LEDs on the power supply, show chassis commands, and messages on the craft interface
LCD—to indicate that the power supply is functioning normally. Ignore error indicators
that appear during the first 60 seconds.
7. On the external management device connected to the Routing Engine, monitor the startup process to
verify that the system has booted properly.
