Onsite/Remote
Security Level
Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected
last. Statement 1046
Warning
Hazardous voltage or energy may be present on DC power terminals. Always replace cover when
terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in place.
Statement 1075
Note
The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE Issue 5.
Caution
The ONS 15454 M6 relies on the protective devices in the building installation to protect against short circuit,
overcurrent, and ground faults. Ensure that the protective devices are properly rated and comply with national
and local codes.
Note
If the system loses power or both TNC, TNCE, TSC, or TSCE cards are reset and the system is not provisioned
to get the time from a Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server, you must
reset the ONS 15454 M6 clock. After powering down, the date defaults to January 1, 1970, 00:04:15. To reset
the clock, see the "NTP-G24 Setting Up Node Identification Information" procedure in the Cisco ONS 15454
DWDM Control Card and Node Configuration Guide. If you are using the TNC, TNCE, TSC, or TSCE cards,
the system clock will run for up to three hours. In this case, no action would be required.
Procedure
Step 1
Connect the return cables of the power supply to the Earth ground located at the power supply side.
