8.Repeat Step 7 for the remaining power supplies installed in the switch.

9.On the external management device, monitor the startup process to ensure that the system boots properly.

NOTE: After you power on a power supply, wait for at least 60 seconds before you turn it off. After you power off a power supply, wait for at least 60 seconds before you turn it back on.

If the system is completely powered off when you switch on a power supply, the SRE or RE module boots as the power supply completes its startup sequence.

After you power on a power supply, it can take up to 60 seconds for status indicators such as power supply LEDs and the show chassis operational mode CLI command display to indicate that the power supply is functioning normally. Ignore any error indicators that might appear during the first 60 seconds.

Connecting an EX Series Switch to a Management Console

You can configure and manage an EX Series switch using a dedicated console. Every EX Series switch has a console port with an RJ-45 connector. Use the console port to connect the EX Series switch to the management console or to a console server. The console port accepts a cable with an RJ-45 connector.
