Plug the LC duplex connector of the fiber into a Cisco-supported SFP or XFP.
Step 3
If the new SFP or XFP has a latch, close the latch over the cable to secure it.
Step 4
Plug the cabled SFP or XFP into the card port until it clicks.
Step 5
To change the payload type of an SFP or XFP (called pluggable port modules [PPMs] in CTC), refer to

Loss of power or low voltage, resulting in a loss of traffic and causing the LCD clock to reset
Loss of power or low voltage.
Possible Cause
Possible Cause Improperly connected power supply.
The ONS 15454 requires a constant source of DC power to properly function.
Recommended Action
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 (single-shelf mode) or shelf view
(multishelf mode) click the Provisioning > General > General tab and change the Date and Time
fields. Complete the "Isolate the Cause of Power Supply Problems" procedure on page
