6. Place the removed FAN unit on an antistatic conductive mat.

Step 4

and

Step 5

in reverse order. Align the FAN unit with the slot guides,

insert it carefully, and secure it firmly.

Caution –

Each cabinet contains multiple FAN unit so that the cooling

specifications are satisfied even if one FAN unit fails. When replacing a FAN unit,
however, replace it as quickly as possible.

Caution –

Do not forcibly push the FAN unit when inserting it, even if it is not

moving smoothly. If the FAN unit is forcibly inserted despite the presence of any
obstruction in a slot or any problem with a connector pin, serious damage may
result.
