After the router is powered on, status indicators—such as LEDs on the front panel
and
show chassis command output—can take up to 60 seconds to indicate that the
power supply is functioning normally. Ignore error indicators that appear during the
first 60 seconds.
If you need to power off the router after the Routing Engine finishes booting, use the
J-Web interface or the CLI to halt the Services Router first. For instructions, see the
J-series Services Router Administration Guide. Alternatively, you can press and release
the power button to gracefully shut down the router. For more information, see
“Powering a Services Router On and Off” on page 129.
STATUS LED
When the system is powered on, the STATUS LED changes from off to blinking green.
Startup takes approximately 90 seconds to complete. If you want to turn the system
off and on again, we recommend waiting a few seconds between shutting it down
and powering it back up. Table 8 on page 21 describes the
STATUS LED.
