each procurve switch 8100fl chassis is shipped with two fan trays to provide cooling for the modules. each fan tray assembly is installed below the vertical slots. the fan tray assembly is hot-swappable so you can replace the assembly yourself while the switch is powered on.

    to ensure that the fan tray assembly can provide adequate cooling, always provide a minimum of 3 inches (7.62 centimeters) of clearance behind the chassis. adequate ventilation is provided from the front as long as you maintain sufficient clearance to add or remove modules.

    to install a fan tray (5069-7936):

    1. align the fan tray guides with its corresponding slot and push in until the fan tray mounting plate contacts the chassis frame.

   

    2. tighten the two screws on each side of the fan tray housing using a slotted or phillips screw driver. (hand tightening the captive screws may not be sufficient to prevent normal fan vibration from allowing the assembly to work loose and become disconnected.)

    3. repeat steps 1 and 2 to install the second fan tray.

    if you want to change a fan tray, remove the old tray and insert a new one as quickly as possible to maintain proper cooling of the chasis.
