The fan tray is hot swappable. Follow these guidelines when you replace the
fan tray on an operating 12916E switch:
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.
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 the hot-swapping to minimize the operation time.
Before you install or replace a switching fabric module on an operating
12916E switch, first remove the fan tray. Install the fan tray immediately after
you finishing installing or replacing the switching fabric module.
For good ventilation, install filler panels in empty switching fabric module slots.
Long-time exposure to strong air flow might cause discomfort. To avoid this
hazard, do not stand close to the air outlet vents while 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.

HPE FlexFabric 12916E LSXM116XFAN Fan Tray User Manual-6PW101
The LSXM116XFAN fan tray (JH106A) contains six fans. It applies to the
12916E switch. The 12916E switch has two fan tray slots: FAN1 and FAN2.
One fan tray is sufficient for heat dissipation of the switch. As a best practice,
install two fan trays on the switch for redundancy and noise reduction. When
the fan tray is operating, ambient air flows in through the air vents in the MPU
and LPU/interface module adapter panels, circulates through the switching
fabric module section, and flows out through the air vents in the fan tray with
the heat carried from the MPU, LPU, and switching fabric module sections.

Installing a fan tray
Before you install a fan tray, first install the switching fabric modules or filler
panels in the switching fabric module slots.
The procedures are similar for installing a fan tray in FAN1 slot and FAN2 slot.
To install a fan tray in FAN1 slot, align the top and left edges of the fan tray in
the slot. To install a fan tray in FAN2 slot, align the top and right edges of the
fan tray in the slot.
