NEC Sever Switch Unit N8191-09 - Manual (Page 23)

Warning Labels
The warning label is attached to components with possible danger or their vicinity in the server switch
unit to inform the user that a hazardous situation may arise when operating the unit (do not take off
any label or soil it). If you find any label unattached, almost peeled off, or soiled, making the warning
illegible, contact your service representative.
