Possible Problem Solution

Loss of power or low

voltage

See Chapter 2, “Alarm Troubleshooting,” for information about specific

power alarms. Procedures for installing power supply and cables are located

in the “Install Hardware” chapter of the Cisco ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide. Power supplies may be

disconnected by reversing the appropriate procedure (for AC or DC power).

Note The ONS 15310-CL and ONS 15310-MA require a constant source

of DC power to properly function. Input power is –48 VDC. Power

requirements range from –42 VDC to –57 VDC.

Note A newly installed ONS 15310-CL or ONS 15310-MA that is not

properly connected to its power supply does not operate. Power

problems can be confined to a specific node or can affect several

pieces of equipment on the site.

Note A loss of power or low voltage can result in a loss of traffic and

causes the LCD clock on the node to default to January 1, 1970,

00:04:15. To reset the clock, in node view click the Provisioning >

General tabs and change the Date and Time fields.
