Fan Tray Replacement Instructions
for the ProCurve Series 3500yl and 6200yl Switches
The fan tray is not hot swappable. Replacing the fan tray must be done during scheduled downtime.
When a fan fails the Fan Status LED on the switch will blink simultaneously with the switch Fault
LED. In this case, the entire fan tray needs to be replaced. Individual fans cannot be replaced.
