CAUTION:
When you hot swap fan trays, follow these guidelines:
•
Ensure electricity safety.
•
Replace a fan tray only when two other fan trays are operating correctly.
•
To prevent dust from entering the chassis, keep the failed fan tray in position before the
replacement and finish replacing the fan tray within 3 minutes.
•
When you hot swap a fan tray, the fan speed of the remaining fan trays automatically increases.
Take noise protection measures such as wearing an earmuff or earplug. In addition, make
preparations before hot swapping a fan tray to minimize the operation time.
IMPORTANT:
A fan tray covers fabric module slots. Install fabric modules or filler panels in the fabric module slots
before installing a fan tray.
•
If a fabric module is installed in a fabric module slot, make sure the spring clips lock the ejector
levers of the fabric module in place.
•
If a fabric module filler panel is installed in a fabric module slot, make sure the ejector levers of
the fabric module filler panel are secured in place by captive screws.
IMPORTANT:
Captive screws are required to install a fan tray on the device. As a best practice, fasten a captive
screw to a torque of 5.5 kgf-cm (4.77 lbf-in).
The device has three fan tray slots. You can install three fan trays in 2+1 redundancy for the device.
As a best practice, install a fan tray in each slot for redundancy and to reduce noises.
When you install a fan tray in FAN1, make sure the fan tray engages the top left of the slot. When you
install a fan tray in FAN3, make sure the fan tray engages the top right of the slot.
To install a fan tray in a slot, for example, FAN1:
1. As shown by callout 1 in Figure 3-18 , unpack the fan tray, and then pivot up the two fan tray
handles.
2. Orient the fan tray with the lettering on it facing upward and align the fan tray with the fan tray
slot.
3. As shown by callout 2 in Figure 3-18 , holding the upper fan tray handle with one hand and the
lower fan tray handle with the other, insert the fan tray into the slot along the guide rails. Keep
the fan tray as straight as possible.
4. As shown by callout 3 in Figure 3-18 , fasten the captive screws on the fan tray.
5. As shown by callout 4 in Figure 3-18 , pivot down the fan tray handles until they engage the edge
of the fan tray.
