Power On Your Prestige

At this point, you should have connected the console port, the LAN port, the cable port and the power port
to the appropriate devices or lines. Plug the power adapter into a wall outlet.
When connected and powered on, the cable modem executes an automatic installation procedure:
1. Scans and locks on to the service provider's downstream frequency.
2. Obtains timing, signal, power level, authentication, addressing, and other operational parameters from
the CATV CMTS/headend.
3. Downloads its configuration file and is then operational.
During the initialization:
1. The Power LED should be on. The SYS LED will come on after the system tests are complete and then
stays on when the automatic installation procedure is complete.
2. The CABLE LED will be flashing for 2 seconds on/off cyclic duration while scanning downstream
channel and then with 1 second on/off cyclic duration when it has locked on to downstream channel and
is communicating with headend CMTS. Once the cable connection is complete it will remain ON.
3. The DATA LED will be flashing when the cable downstream, cable upstream or LAN is receiving and
transmitting data. It will OFF when the connection is idle.
4. The LAN10M LED or LAN100M LED (depending on the Ethernet Speed connected) will be ON if
Ethernet link is successful and flashing while sending/receiving.
