Fan Module Overview

Depending on the switch model, five individual fan modules (C9500-32C and Catalyst 9500 Series switches),
two fan trays with dual-stacked fans (C9500-24Y4C, C9500-48Y4C and C9500-32QC) or six individual fan
modules (C9500X-28C8D) are available. In models using 5 fan modules, the switch can operate with 4
operational fans and 1 nonfunctional fan and in models using 6 fan modules, the switch can operate with 5
operational fans and 1 nonfunctional fan. Any failed fan should be replaced as soon as possible to avoid service
interruption due to a second fan fault.
For the switch to boot-up, ensure the following conditions are met.
• the switches using FAN-T4-R and C9K-T2-FANTRAY= modules must at a minimum have 4 fans
• the switches using C9K-T1-FANTRAY modules must have 2 fan tray modules with all the fans operating
• the switches using C9500X-FAN-1U-R or C9500X-FAN-1U-F modules must at a minimum have 4 fans
If the switch fails to meet the minimum number of required fans, the switch shuts down automatically to
prevent the system from overheating.
