Replacing Components
This chapter shows you how to remove and install the following components:
■ Fan tray (see page 4-1)
 Hot Swapping This component can not be hot swapped. The switch must be powered off to 
replace the fan tray. 
Caution The HP ProCurve 3500, 3500yl and 6200yl switches and its components are 
sensitive to static discharge. Use an antistatic wrist strap and observe all static 
precautions when replacing components. 
Replacing the fan tray
The fan tray is not hot swappable. Replacing the fan try 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.
WARNING To avoid the possibility of electric shock, all power cords must be 
disconnected from the switch before starting this procedure.
To replace a fan tray:
1. Disconnect the power cables from the switch. 
2. Using a Torx T-10 screwdriver remove all the screws securing the top of 
the switch and remove the top.
