Fan and fan blank
Fan population guidelines
To provide sufficient airflow to the system if a fan fails, the server supports redundant fans.
Single processor, non-redundant configuration:
o Fans are required in fan bays 1–4.
o Fan blank is required in fan bay 5.
o Fan bays 6–10 have a single fan cage cover.
Single processor, redundant configuration:
o Fans are required in fan bays 1–4 and 6–9.
o Fan blank is required in fan bay 5.
o Fan bay 10 is empty.
Dual processor, non-redundant configuration:
o Fans are required in fan bays 1–5.
o Fan bays 6–10 have a single fan cage cover.
Dual processor, redundant configuration—Fans are required in all 10 fan bays.
In a redundant fan mode:
o If one fan fails, the system continues to operate without redundancy. This condition is indicated by
a flashing amber Health LED.
o If two fans fail, the system shuts down.
The minimum fan requirement to make this server bootable is:
o Fans 1–4 in a single processor configuration
o Fans 1–5 in dual processor configuration
