The fan-tray assembly features an air filter at the bottom of the tray that you can install and remove by
hand. Remove and visually inspect this filter every 30 days and keep spare filters in stock. Refer to the
"Maintain the Node" chapter in the Cisco ONS 15454 DWDM Procedure Guide for information about
