[j-nsp] EX4200 virtual chassis

[Victor Sudakov]

Dear Colleagues,

We are planning to add backup switches in a Virtual Chassis
configuration to our existing EX4200s.

I have read
https://www.juniper.net/documentation/en_US/junos/topics/concept/virtual-chassis-ex4200-components.html
and
https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/virtual-chassis-ex4200-cli.html
so the configuration is more or less clear to me. There is one question left however. 

If I have a standalone EX4200, should I power it off before plugging
in the Virtual Chassis Cable for the first time, and connecting
another (powered off) EX4200? 

The links above say only that the desired master should be powered on
first, but nothing is said about the possibility of hot plug
connection.
