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.
Note
To replace the fan-tray assembly, it is not necessary to move any of the cable management facilities.
