Powering Off the PTX5000 During FPC Upgrade

To power off the PTX5000, follow these steps:
1. On an external management device connected to the Routing Engine, issue the request system halt
both-routing-engines operational mode command. The command shuts down the Routing Engines
cleanly, so their state information is preserved.
If the PTX5000 contains only one Routing Engine, issue the request system halt command.
user@host> request system halt both-routing-engines
2. Wait until a message appears on the console confirming that the operating system has halted.
Halt the system ? [yes,no] (no) yes
*** FINAL System shutdown message from user@host ***
System going down IMMEDIATELY
