HPE FlexFabric 12902E Manuel utilisateur
The fan tray is hot swappable. Follow these guidelines when you replace the fan tray
on an operating switch:
Ensure electrical 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.
When you hot-swap a fan tray, the remaining fan tray 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 hot
swapping a fan tray to minimize the operation time.
Long-time exposure to strong air flow might cause discomfort. To avoid this hazard,
do not stand close to the air outlet vents when the switch is operating. If you must be
next to the switch on the air outlet vent side for an extended period, avoid the air flow
or take other protective measures.

panels and exhausts the air carrying heat through the air vents in the fan tray panel.
