The 15454-M2-FTA and 15454-M2-FTA2 are installed in the ONS 15454-M2 shelf assembly. For information
on the ONS 15454 M2 fan-tray assembly, see the Fan-Tray Assembly, on page 234. The 15454-M6-FTA and
15454-M6-FTA2 are installed in the ONS 15454-M6 shelf assembly. For information on the ONS 15454 M6
fan-tray assembly, see the Fan-Tray Assembly , on page 387.
Note
Fan Speed
Fan speed is controlled by the TCC2/TCC2P/TCC3 card’s temperature sensors. The sensors measure the input
air temperature at the fan-tray assembly. Fan speed options are low, medium, and high. If the
TCC2/TCC2P/TCC3 card fails, the fans automatically shift to high speed. The temperature measured by the
TCC2/TCC2P/TCC3 sensors appears on the LCD screen.
Fan Failure
If one or more fans fail on the fan-tray assembly, replace the entire assembly. You cannot replace individual
fans. The red Fan Fail LED on the front of the fan-tray illuminates when one or more fans fail. The red Fan
Fail LED clears after you install a working fan-tray.
As with the FTA3, the 15454E-CC-FTA (for ETSI) and 15454-CC-FTA (for ANSI) Fan Fail LED on the
front of the fan-tray assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or
AIP replacement is required. But the Fan Fail LED on the 15454E-CC-FTA and 15454-CC-FTA will also
illuminate when only one power source is connected to the chassis, and or any fuse blows. In such conditions,
the Fan Alarm is triggered and the fans run at maximum speed.
