request

Note: If your routing platform contains two Routing Engines and you want to shut the power off to the routing platform or remove a Routing Engine, you must first halt the backup Routing Engine (if it has been upgraded) and then the master Routing Engine. To halt a Routing Engine, issue the request system halt command. You can also halt both Routing Engines at the same time by issuing the request system halt both-routing-engines command.

If you want to reboot a router that has two Routing Engines, reboot the backup Routing Engine (if you have upgraded it) and then the master Routing Engine.

Caution: Halt the backup Routing Engine before you remove it or shut off the power to the router; otherwise, you might need to reinstall the JUNOS software.

Note: If you reboot the TX Matrix platform, all the T640 master Routing Engines connected to the TX Matrix platform reboot. If you halt both Routing Engines on a TX Matrix platform, all the T640s Routing Engines connected to the TX Matrix platform are also halted.

Note: If you insert a Flexible PIC Concentrator (FPC) into your routing platform, you may need to issue the request chassis fpc command (or press the online button) to bring the FPC online. This applies to FPCs in M20, M40, M40e, M160, M320, and T-series platforms. For command usage, see the request chassis fpc command description in the JUNOS System Basics and Services Command Reference.
