Initialization Sequence

Each line module is initialized independently. As a result, the CLI on the SRP module
can become available before the line modules have completed initialization.
Commands relating to a line module might fail if the module has not completed
initialization. You can use the show version command to display line module status,
but do not enter commands for a line module until its state is online.

Status LEDs

Upon initial power-up, the components of the router run boot code, go through a
series of self diagnostic tests, and synchronize with each other.
When the tests are complete, use the LEDs on each module to determine the status
of the router. Observe the module LEDs on the front and rear components.
See "Troubleshooting" on page 79 for information on the system's LEDs.

Status LEDs
Verify that the power source is operational and turned on.
Inspect all grounding and power connections to the router chassis.
Confirm that all connections are secure.
Switch the power switches to ON.
Monitor the LEDs on the SRP modules and SFM modules to verify that the system
is booting properly. See Table 11 on page 84 for LED status explanations.
When the prompt appears on the system console, the system is in User Exec
mode and is ready to be configured:
host1>
Enter the enable command to access Privileged Exec mode:

host1#
In Privileged Exec mode you can begin to configure the system. See JUNOSe
