Statement 1075
Warning
The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE Issue 5. Note
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.
Caution
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.
