Smart UPS Modular Ultra display remains blank
Issue:
The UPS display is blank and will not respond
Product Line:
Smart UPS Modular Ultra
Environment:
All models, all serial numbers
Resolution:
If the display is blank on startup or after a display/NMC reboot and the NMC status LED (behind the door to the right of the display) is:
- solid orange, this usually indicates the display firmware is stuck in the boot loader. Press and hold the Reset button (located in the pinhole) until the LED changes from solid orange and begins progressing through other LED states. During the recovery process, the LED may:
- Change from solid orange to flashing green.
- After approximately 20 seconds, change to flashing orange.
- Turn off completely after the Reset button is released.
- Remain off for several minutes before resuming normal startup activity.
- Progress through additional orange and green LED indications before the display powers on.
- Important: Do not assume the recovery procedure has failed if the LED turns off after releasing the Reset button. Allow several minutes for the display to complete its recovery and boot sequence. The display may not become active immediately.
- on and doing something other than indicating solid orange, the wrong firmware is most likely installed on the display. Check the currently installed NMC/Display firmware on the UPS via the console port to the right of the display. After, please install the correct NMC/Display firmware
- completely off, check the connections to the back of the display. The mini HDMI cable might be disconnected. You may also look for any damage to the cables/connections.
If none of these address the blank screen, please contact the Customer Care Center to get the display replaced.
