Note If the fan-tray assembly is removed from the shelf assembly, wait for at least 5 seconds before plugging
it back into the shelf. In the event the LCD display in the fan-tray assembly appears blank, remove the
unit from the shelf, wait for at least 5 seconds and reinsert the unit into the shelf.
Install the air filter. The air filter can be installed internally between the fan tray and shelf assembly, or
Step 1
externally by mounting the air filter bracket on the bottom of the shelf assembly. Slide the air filter into
the bracket.
Caution Although the air filter can work with older fan trays if it is installed with either side facing up, Cisco
recommends that you install it with the metal bracing facing up to preserve the surface of the filter. You
must install the air filter with the metal bracing facing up with 15454E-CC-FTA or 15454-CC-FTA.
Step 2 Install the fan-tray assembly.
