Description
The Cisco A903-FAN-E is an enhanced fan tray designed for the Cisco ASR 903 Aggregation Services Router. This spare fan tray provides reliable system cooling and supports continuous operation by maintaining optimal airflow within the chassis. It includes a dedicated filter slot that allows the installation of an optional dust filter for improved protection in challenging or dusty environments.
Built as a field-replaceable unit, the A903-FAN-E enables quick servicing and minimal downtime during maintenance or replacement. Redundant fan design ensures continued operation even in the event of a single fan failure, making it ideal for service provider and enterprise deployments that demand high availability.
