Fan-Tray Assembly
The fan-tray assembly is located at the bottom of the ONS 15454 SDH front
compartment (Figure 27). The fan tray is a removable drawer that holds fans and fan
control circuitry for the ONS 15454 SDH. After the fan tray is installed, it only needs
to be accessed if a fan failure occurs or to replace or clean the fan-tray air filter.
