2.3.3.3.2 Removing and Installing the ES4710BD Fan Tray
The ES4710BD has three fan trays in the upper section of the switch, and can be
serviced from the front. The installation and removal of the fan tray is relatively simple. To
install, just hold the fan tray in the correct direction, align with the corresponding slot and
push to secure. The locker in the front panel of the fan tray will lock automatically. Upon
removal, hold the handle in the front panel of fan tray with your middle and ring fingers,
press the locker slightly down, and the fan tray can be drawn out smoothly.
Note: The fan trays are installed on switch chassis shipment.
