Figure2-14 Installing a fan tray
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
and FAN-40B-1-A fan trays.
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.
