(Optional) Configure the static routes to remote subnets with access to the management port. Access to the management port is limited to the local subnet. To access the management port from a remote subnet, you need to add a static route to that subnet within the routing table. For more information about static routes, see the Junos OS System Basics Configuration Guide.

Do not insert the removable media during normal operations. The router does not operate normally when it is booted from the removable media. When the router boots from the storage media (removable media, CompactFlash card, or hard disk) it expands its search in the /config directory of the routing platform for the following files in the following order: juniper. conf (the main configuration file), rescue. conf (the rescue configuration file), and juniper. conf. 1 (the first rollback configuration file). When the search finds the first configuration file that can be loaded properly, the file loads and the search ends. If none of the file can be loaded properly, the routing platform does not function properly. If the router boots from an alternate boot device, the Junos OS displays a message indication this when you log in to the router. [. . . ] On a DC-powered router, the switches are on the circuit breaker box. 3. On the console or other management device connected to the master Routing Engine, enter CLI operational mode and issue the following command to shut down the router software. (If two Routing Engines are installed, also issue the command on the backup Routing Engine. ) 4. Shut down power to the router by pressing the power switch for all power supplies to the off (O) position. [. . . ]
