Powering Up and Checking LEDs
Once you have completed the steps described in the previous sections for both the Megabit
Modem 310F and 320F, you are ready to power up each modem.
1 Plug the Megabit Modem 310F power supply into the facility power and ensure the
Power LED is lit solid green.
2 Plug the Megabit Modem 320F power supply into the facility power and ensure the
Power LED is lit solid green.
3 Allow the modems approximately 30 to 60 seconds to synchronize.
4 After both modems are powered up, verify the following LED indications on each modem:
• 10BASE-T LINK LED is solid green (when the Ethernet port is connected)
• ADSL SYNC LED is solid green when the Megabit Modem 310F synchronizes with
the Megabit Modem 320F (the LED flashes green when synchronization is lost
between the two modems)
• ADSL MAR LED is solid green if margin is at or above the configured threshold
If conditions other than those listed above exist, check the cabling. See “Installing the Cabling”
on page 6 for instructions.
