1.13 Power Supply Problems
Symptom Loss of power or low voltage, resulting in a loss of traffic and causing the LCD clock to reset
to the default date and time.
Possible Cause Loss of power or low voltage.
Possible Cause Improperly connected power supply.
Recommended Action The ONS 15454 requires a constant source of DC power to properly function.
Input power is –48 VDC. Power requirements range from –42 VDC to –57 VDC. A newly installed
ONS 15454 that is not properly connected to its power supply does not operate. Power problems can
be confined to a specific ONS 15454 or affect several pieces of equipment on the site. A loss of
power or low voltage can result in a loss of traffic and causes the LCD clock on the ONS 15454 to
default to January 1, 1970, 00:04:15. To reset the clock, in node view click the
Provisioning > General > General tabs and change the Date and Time fields. Complete the “Isolate
the Cause of Power Supply Problems” procedure on page 1-149.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
