Service action
If the sensor name is FAN1,
FAN4, FAN5, or FAN8, no service
action is required. If the sensor
name is FAN2, replace Fan 2. If
the sensor name is FAN3, replace
Fan 3. If the sensor name is
FAN6, replace Fan 6. If the
sensor name is FAN7, replace
Fan 7. Go to "5104-22C or
9006-22C locations" on page
63, "9006-12P locations" on
page 75, or "9006-22P
locations" on page 91 to
identify the physical location and
removal and replacement
procedure.
No service action is required.
Ensure that all fans are seated
securely. Go to "5104-22C or
9006-22C locations" on page
63, "9006-12P locations" on
page 75, or "9006-22P
locations" on page 91 to
identify the physical location and
removal and replacement
procedure.
