NOTE:
As a best practice to guarantee the grounding effect, use the grounding cable provided with the
switch to connect to the grounding strip in the equipment room.

Installing/removing fan trays

CAUTION:
The switch has multiple fan tray slots. To ensure good ventilation of the switch, follow these
guidelines to install and remove fan trays:
The switch is provided with the fan tray slots empty. Before powering on the switch, make sure all fan tray
slots have fan trays installed and the fan trays are the same model.
Make sure all slots have a module or filler panel installed when the switch is operating.
If multiple fan trays fail on an operating HPE 5950 32QSFP28 or HPE 5950 48SFP28 8QSFP28 switch, do
not remove the fan trays at the same time. Replace the fan trays one after another and finish replacing a
fan tray within 3 minutes.
If a fan tray fails on an operating HPE 5950 4-slot switch, replace the fan tray immediately and keep the
failed fan tray in position before replacement. If two fan trays fail, finish replacing the fan trays within 1
minute.
The installation and removal procedures are the same for the X712 Bck(pwr)-Frt(prt) HV2 Fan Tray,
X711 Frt(prt)-Bck(pwr) HV2 Fan Tray, 5930 4-slot F(prt) B(pwr) Fan Tray, and 5930 4-slot F(prt)
B(pwr) Fan Tray. The following installation and removal procedures use the X712 Bck(pwr)-Frt(prt)
HV2 fan tray as an example.
