About Fan Modules

Hot-swappable fan modules (fan trays) are provided in all switches in the Cisco MDS 9000 Family to manage

• One or more fans fail within a fan module—Even with multiple fan failures, switches in the Cisco MDS
• The fan module is removed for replacement—The fan module is designed to be removed and replaced
