DLP-G4 Install the External Brackets and Air Filter (ANSI Only)
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 15454-CC-FTA.
Purpose This task installs the external brackets and air filter on the bottom of the
shelf rather than below the fan-tray assembly. Installing the external
brackets and air filter on the bottom of the shelf enables access to the air
filter without removing the fan-tray assembly. This task applies to the
ONS 15454 ANSI shelf only.
