Removal and Replacement Procedures 2-13
Fans
The ProLiant ML570 server ships standard with two hot-plug system fans (one CPU and one
I/O) and three redundant, hot-plug drive fans. The two system fan baskets are designed to allow
for a redundant hot-plug fan in each basket. Figure 2-6 and Table 2-1 show the location of all
fans in the ProLiant ML570 server, including the fan name and primary function.
NOTE: Fans may continue to spin after a temporary failure occurs. Replace failed fans (amber LED) even
if spinning continues.
