Chapter 2: J-series Services Router Hardware Features

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 JUNOS Software 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 89.

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 7 on page 15 describes the STATUS LED.
