Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046
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-G24 Set Up Name, Date, Time, and Contact Information” procedure on
page 3-10. If you are using the TCC2/TCC2P cards, the system clock will run for up to three hours. In
this case, no action would be required.
Step 1 Connect the office power according to the fuse panel engineering specifications.
Step 2 Measure and cut the cables as needed to reach the ONS 15454 from the fuse panel. Figure 1-18 shows
the ONS 15454 power terminals.
Step 3 Dress the power according to local site practice.
