An E4G series router starts when it is connected to a power source.
When a router starts for the first time, it can take up to 40 minutes for the clock function to stabilize and allow the T1 lines to hold synchronization.
Fans in the router might not start immediately when the unit is connected to power. This is normal: the system cycles the fans on and off automatically in response to the unit's cooling requirements.
Refer to the ExtremeXOS Quick Guide for information about configuring ExtremeXOS for your E4G router.
