Maintaining the ONS 15454 M12 (ANSI and ETSI), ONS 15454 M2 and ONS 15454 M6 Shelf
Security Level
Caution
The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 R3.1 and later shelf assemblies
(15454-SA-ANSI, P/N: 800-19857; 15454-SA-HD, P/N: 800-24848). The fan-tray assembly includes a pin
that prevents it from being installed in ONS 15454 shelf assemblies released before ONS 15454 R3.1
(15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result
from attempting to install the 15454-FTA3 in a incompatible shelf assembly.
Caution
Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the
connectors on the backplane.
Caution
15454-CC-FTA (ANSI) is compatible with Software R2.2.2 and greater, and shelf assemblies 15454-SA-ANSI
and 15454-SA-HD. 15454E-CC-FTA (ETSI) is compatible with Software R4.0 and greater, and shelf assembly
15454-SA-ETSI.
Caution
As with the FTA3, the 15454E-CC-FTA and 15454-CC-FTA 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.
Note
To replace the fan-tray assembly, it is not necessary to move any of the cable management facilities.
