Powering Off the AC-Powered MX2020 Router
 | Note: After powering off a PSM, wait at least 60 seconds before turning it back on. |
To power off the router:
- On the external management device connected to the CB-RE,
issue the request system halt both-routing-engines operational mode command. The command shuts down the Routing Engine
cleanly, so their state information is preserved. If the router contains
only one CB-RE, issue the request system halt command.
user@host> request system halt both-routing-engines - Wait until a message appears on the console confirming
that the operating system has halted. For more information about the
command, see the Junos OS System
Basics and Services Command Reference
