Caution Do not operate an ONS 15454 without a fan-tray air filter. A fan-tray air filter is mandatory.
Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 Release 3.1 or later shelf
assemblies (15454-SA-ANSI, 800-19857; 15454-SA-HD, 800-24848). It includes a pin that does not
allow it to be installed in ONS 15454 shelf assemblies released earlier than ONS 15454 Release 3.1
(15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N 800-0714915454). Installing the
15454-FTA3 in a noncompliant shelf assembly might result in failure of the alarm interface panel (AIP),
which in turn, will result in power loss to the fan-tray assembly.
Note 15454-CC-FTA is compatible with Software Release 2.2.2 and greater and shelf assemblies
15454-SA-HD and 15454-SA-ANSI.
Caution You must place the edge of the air filter flush against the front of the fan-tray assembly compartment
when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter, the
fan tray, or both.
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 back panel of the shelf assembly.
Caution If the fan tray does not slide all the way to the back of the shelf assembly, pull the fan tray out and
readjust the position of the reusable filter until the fan tray fits correctly. Be sure that the grid on the
reusable filter is on the side facing the fan tray.
Purpose This procedure installs the fan-tray assembly. Refer to the Cisco ONS
15454 Reference Manual for specific information about fan-tray assembly
compatibility and air filters.
