3.
Orient the fan tray with the TOP mark facing up.
4.
Align the fan tray with the fan tray slot. Holding the fan tray handles, slide the fan tray into the
slot along the guide rails. Make sure the fan tray is fully seated in the slot and has a firm contact
with the backplane.
To prevent damage to the fan tray or the connectors in the chassis, insert the fan tray gently. If
you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it
again.

IMPORTANT:
•
At the first login to the switch, use the
fan prefer-direction
command to set the airflow
direction of the switch to be the same as the airflow direction of the fan trays. If the fan trays have
a different airflow direction than the switch, the system outputs traps and logs to notify you to
replace the fan trays.
•
By default, the switch uses the same airflow direction (power-to-port) as the LSWM1FANSCBE
fan tray.
Removing a fan tray
WARNING!
•
To avoid bodily injury, disturbing the dynamic balance of the fan tray, and causing loud noises, do
not touch the rotation axis, or any bare wires, fan blades, or terminals on the fan tray.
•
Do not place the fan tray in a moist place. Prevent liquid from entering the fan tray.
•
Fan trays with faulty internal wiring and conductors require maintenance from maintenance
engineers. Do not disassemble the faulty fan trays.
To remove a fan tray:
1.
Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably
grounded.
2.
Holding the fan tray handles, pull the fan tray slowly out of the slot along the guide rails.
3.
Put the removed fan tray in an antistatic bag.
