Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers
Indicator Lights at Startup
When the enclosure powers up, the indicator LEDs respond as follows:
* IOS (Initial Operating System) is the base layer operating system on Enova DGX Switcher equipment. IOS
performs functions such as hosting higher level run-time software applications. If unexpected critical errors are
encountered within such hosted applications, system control of the equipment may be passed to the IOS layer
preventing normal system operation until the error is manually cleared. Report all such errors to technical support
(see page 62).
Important: If the indicator LEDs do not respond with a normal display as stated above, check power
connections, before contacting technical support (see page 62).
Redundant Power Supply (RPS)
Every enclosure ships with two mutually-redundant (hot-swappable) power supplies.
The Power indicator on the front of the enclosure illuminates a constant red if a problem occurs with one
of the power supplies. Check the AC and DC LED indicators on the left of each power receptacle to
determine if a power supply is not working. For additional LED information, see above.
Important: A failed power supply should be replaced as soon as possible to maintain the system’s
power redundancy. For replacement information, contact technical support (see page 62).
Power Supply Troubleshooting
 If a power supply’s AC and DC power indicator LEDs are not illuminated: Check to
be sure the power cord is completely plugged into the enclosure and the power source.
 If a power supply’s DC LED illuminates amber or red, contact technical support
(see page 62).
Caution: Do not remove a failed power supply until the replacement is ready to install, unless
directed to do so by technical support.
