Configuration on first use 

 

Before the Transcoder can be used for the first time, it is essential to configure it for use on the network 

and change the local account passwords from their defaults.  Automatic login is configured by default, 

but this should be changed for platform security reasons.  If the local account passwords are lost, they 

cannot be reset so the Transcoder will need to returned to Cabletime for a full system re-install. 

 

The default passwords for user 

cabletime

 and user 

root

 are:  cabletime 

 

 

Use the local monitor, keyboard and mouse for the following actions:
