• The external clock inputs on the SONET Clock Generators (SCGs) are not supported for JUNOS OS Release 10.1 and earlier.
• After powering on or off a power supply, wait at least 60 seconds before turning it back off or on again.
• 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.
