Warning
Do not apply power to the ONS 15454 until you complete all installation steps and check the continuity
of the –48 VDC and return.
Note The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE Issue 3.
Note If the system loses power or both TCC2/TCC2P 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 clock. After powering down, the date defaults to January 1, 1970, 00:04:15. To reset
the clock, see the “NTP-A25 Set Up Name, Date, Time, and Contact Information” procedure on
page 4-4.
If you are using the TCC2/TCC2P cards, the system clock is kept running for up to three hours. In this
case, no action is required.
Note If you encounter problems with the power supply, refer to the Cisco ONS 15454 Troubleshooting Guide.
