Powering On the Router
Warning The plug-socket combination must be accessible at all times because it serves as the main
disconnecting device. To see translations of the warnings that appear in this publication, refer to
the Regulatory Compliance and Safety Information document that accompanied this device.
Caution Never operate the router unless the unit is completely closed, to ensure adequate cooling.
Take the following steps to power on the router:
Step 1 For routers with AC input, plug the router’s power cord into a three-terminal, single-phase power
source that provides power within the acceptable range.
Step 2 Power on the router. The LED labeled SYSTEM on the front panel should come on.
If you encounter problems when you power on the router, see the “Troubleshooting” section that follows.
