Cisco C9610 Series Smart Switches Hardware Installation Guide
Guidelines for removing and reinstalling a fan tray on Cisco C9610 switch.
The Cisco C9610 series smart switches ship with preinstalled fan trays. Before removing or installing a fan tray ensure that you follow the guidelines and safety warnings.
When removing a fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray.
While the fan tray is designed to be removed and installed while the system is operational (powered on) without presenting an electrical hazard or damage to the system, there is a time constraint when you remove and replace the fan tray in a system that is powered on.
The system can safely run without a fan tray only for a few minutes, until the critical temperature threshold is exceeded. Watch for any alarms triggered in the software. After the critical temperature threshold exceeds without sufficient cooling, the system shuts down if the alarm is not cleared.
You can remove and replace the fan tray only from the rear of the chassis.
When you remove and replace a fan tray in a non-operating system, there is no time constraint.
When you order a spare, a fan tray that contains six fans and a connector are shipped. Even if one of the fans is not functioning and you need to replace the fan, you must order a fan tray; individual fans cannot be ordered.
Fan trays are hot-swappable. You do not need to power down the system to remove fan trays.
Read the safety instructions in the Install a fan tray section.
