Installing and removing fan trays
Follow these restrictions and guidelines when you install a fan tray:
•The switch has two fan tray slots: FAN1 and FAN2. Install two fan trays on the switch.
•To prevent dust from entering the chassis, keep the filler panels or fan trays in position if the
switch is not in use.
•The fan tray is hot swappable. Follow these guidelines when you hot swap a fan tray:
{Ensure electricity safety.
{Replace a fan tray only when the other fan tray is operating correctly.
{To prevent dust from entering the chassis, keep the failed fan tray in position before the
replacement.
•To install a fan tray in slot FAN1, orient the fan tray so that the LED is on the left side of the
front panel. To install a fan tray in slot FAN2, orient the fan tray so that the LED is on the right
side of the front panel.
•To avoid damaging the fan tray, use both hands when installing or removing a fan tray.
•When you hot swap a fan tray, only one fan tray is operating and it automatically increases the
fan rotation speed and makes louder noise. Take protection measures such as wearing an
earmuff or earplug. In addition, make good preparation before the hot swapping to minimize
the operation time.
Installing fan trays
To install a fan tray in slot FAN1 for the switch:
1. As shown by callouts 1 and 2 in Figure 13, remove the screws on the filler panel with a Phillips
screwdriver. Supporting the bottom of the filler panel with one hand, use your thumb and
forefinger of the other hand to hold the filler panel through the two holes and pull out the filler
panel along the guide rails.
Keep the removed filler panel secure for future use.
2. Unpack the fan tray.
3. Orient the fan tray correctly. Align the fan tray with the fan tray slot.
4. Holding the fan tray handle with one hand and supporting the bottom of the fan tray with the
