HP ProCurve Switch 4100 Series
Fan Tray Replacement Instructions
This booklet describes the procedures to replace the fan tray in your HP ProCurve
Switch 4100 Series devices. Separate procedures are provided for the Switch 4104,
and Switch 4108 chassis. The procedures are slightly different for these different
sized chassis.
Fan Tray Installation Precautions
Warnings
● Make sure that all AC power is disconnected from the switch
before starting the procedures described in this guide. Do not
reconnect the power until the switch is completely reassembled
and cover plates are replaced on any open module slots or power
supply bays.
● If your switch is rack mounted, make sure that the rack is not
going to tip over as you complete these procedures. If the switch
is difficult to reach, remove it from the rack or other mounting
location before proceeding.
Cautions
● Attach a properly grounded ESD wrist strap to your wrist when han-
dling the switch modules, the fan tray, and the fan tray connector. Do
not touch the components or edge connectors on any printed circuit
boards, or the pins on any connectors. Otherwise, damage due to static
discharge could occur.
● Refer to the installation guides that came with your switch and switch
power supply for precautions on proper handling and installation of the
switch and power supplies. For copies of the installation guides, visit
