Juniper EX9214

• You have installed the required number of power supplies to support redundant operaon for the
switch conguraon.
• You understand how to protect the switch from electrostac discharge (ESD) damage . See
Prevenon of Electrostac Discharge Damage .
Ensure that you have the following parts and tools available:
• An ESD wrist strap
• An external management device such as a PC
• A cable to connect the external management device to the CONSOLE port or the Ethernet
management <...> port on the primary Roung Engine module (RE module).
For connecng a management device to the console port, see Connecng an EX9200 Switch to a
Management Console or an Auxiliary Device . For connecng a management device to the Ethernet
management port, see Connecng an EX9200 Switch to a Network for Out-of-Band Management .
To power on the switch:
1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end
of the strap to the ESD point on the switch.
2. Connect the external management device to the Ethernet management (<...>) port on the primary RE
module.
3. Turn on the power to the external management device.
4. Ensure that the power supplies are fully inserted in the chassis and that each of their handles is ush
against the faceplate.
5. Ensure that the source power cord is inserted securely into the appliance inlet for each AC power
supply.
6. Switch on the dedicated customer site circuit breakers for the power supplies. Follow the ESD and
safety instrucons for your site.
7. Flip the AC input switch on the power supply to the On (|) posion. Observe the power supply
faceplate LEDs. If the power supply is installed correctly and funconing normally, the AC OK and
DC OK LEDs glow steady green. The PS FAIL LED does not glow.
8. Repeat Step 7 for the remaining power supplies installed in the switch.
If any of the status LEDs indicates that the power supply is not funconing normally, repeat the
installaon and cabling procedures. See
Connecng AC Power to an EX9204 Switch , Connecng AC
Power to an EX9208 Switch , or "Connecng AC Power to an EX9214 Switch" on page 174.
9. On the external management device, monitor the startup process to ensure that the system boots
properly.
