CAUTION: Evaluate the overall loading of the branch circuit before you install
any equipment into a rack.
To power up the system:
Verify that the power source is operational and turned on.
1.
Inspect all grounding and power connections to the router chassis.
2.
Confirm that all connections are secure.
3.
Switch the power switches to ON.
4.
Monitor the LEDs on the front of the SRP modules to verify that the system is booting

properly. See Table 11 on page 101 in "Troubleshooting" on page 95 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:
6.
host1>enable
host1#
In Privileged Exec mode you can begin to configure the system. See JunosE System
Basics Configuration Guide, Chapter 2, Command-Line Interface for more information.
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. Do not enter
commands for a line module until its state is listed as online.
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 line module and SRP module LEDs in the front, and the I/O line
module and SRP I/O module LEDs in the rear.
See "Troubleshooting" on page 95 for information on the system's LEDs.
If you need to power down or remove the SRP module, first enter the halt command to
temporarily suspend the system's operation. See JunosE System Basics Configuration
Guide, Chapter 5, Managing the System for more information.
