1. not all features and capabilities referenced in this guide or in the full product manual may be available in your particular unit Therefore some screenshots may differ slightly in appearance We suggest having an assistant on hand when racking up Omnia 9 to help balance the unit during installation and strongly recommend using all 4 rack screws for the best support Although Omnia 9 is fan cooled leaving an empty rack space directly above and below the unit is advisable Physical Installation and Initial Configuration Connect AC power to both of the internal power supplies There is no power switch Failure to use both power supplies is interpreted by the unit as a failure in one of the supplies and will result in an audible alarm which can be silenced by pressing the small red button between the supplies It is always possible for a supply to fail and so having redundant supplies does help protect you against losing power altogether in that event However it is far more likely that the unit will lose power because of an interruption in the circuit feeding the unit Therefore good engineering practice dictates that each supply should be fed from different sources At minimum we recommend that both should be a good quality UPS with adequate surge protection Ideally each would be fed from a completely different circuit for maximum redundancy Next connect the audio inputs as appropriate for your installation Omnia 9 accepts balanced profe2.
