Replace fan filter

Procedure 6-15: Replace fan filter

Overview

Use this procedure to replace a fan filter.

Important!

In central office applications, the fan shelf must equipped with a fan filter. To keep the fan shelf operating properly, it is recommended that users routinely change the fan filter every 6 to 9 months.

In outside plant (OSP) applications, remove the fan filter. Operating Alcatel-Lucent 1665 DMX in an OSP without the fan filter improves air flow and therefore enhances cooling performance and extends the life of the equipment.
