Removing a fan tray
WARNING!
•
Do not touch any bare conductors or terminals on the fan tray.
•
Do not place the fan tray in a moist place. Prevent liquid from entering the fan tray.
•
Do not disassemble faulty fan trays yourself. When the internal wiring or components of a fan tray
are faulty, ask maintenance engineers for maintenance.
•
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:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Grasp the two handles of the fan tray, as shown by callout 1 in Figure 44 , and pull out the fan
tray slowly along the guide rails.
3.
Put the removed fan tray in an antistatic bag.
