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 tray. If the fan tray has a
different airflow direction than the switch, the system outputs traps and logs to notify you to
replace the fan tray.
• By default, the switch uses the same airflow direction (power-to-port) as the LSPM1FANSA fan
tray.

WARNING!
• Do not touch conductors or terminals on the fan trays.
• Do not place the fan tray in 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.
• Take out the fan tray after the fans completely stop rotating. Do not touch the fans even if the fans
stop rotating to avoid affecting fan balance, which might cause loud fan operating noise.
To remove a fan tray:
