HP LSXM104XFAN, User Manual

Page: 1 / 2

To avoid device damage and bodily injury, use two people to install or remove
the fan tray.
The fan tray is hot swappable. Follow these guidelines when you replace a fan
tray on an operating 12904E 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 the hot-swapping to minimize the operation time.
Before you install or replace a switching fabric module on an operating
12904E 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 12904E LSXM104XFAN Fan Tray User Manual-6PW101
The LSXM104XFAN fan tray (JH265A) contains two fans. It applies to the
12904E switch. The 12904E 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.
