H3C S12500R-2L Installation Manual page 28

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 with the LED on the left side of the front
panel. To install a fan tray in slot FAN2, orient the fan tray with the LED 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.
Procedure
1. Unpack the fan tray.
2. Orient the fan tray correctly. Align the fan tray with the fan tray slot.
3. Holding the fan tray handle with one hand and supporting the bottom of the fan tray with the
other, insert the fan tray part way into the slot, as shown by callout 1 in Figure1-7.
Keep the fan tray as steady as possible while inserting it into the slot.
4. Squeezing the captive screw with one hand and holding the fan tray handle with the other, push
the fan tray fully into the slot.
5. Fasten the captive screws on the fan tray.
As a best practice, use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws.
