EonStor F16F-R/S4031-6/4 Installation and Hardware Reference Manual
A retention screw through the extraction handle secures the PSU to the
enclosure. To remove the PSU, the retention screw must be removed first.
When installing a new PSU, make sure that the retention screw has been
firmly secured.
For the PSU specifications, please refer to
Appendix B

Modules
Figure 1-21: Cooling Module
PN: IFT-9273ECFanMod
The redundant cooling modules are contained within PSU modules. When a
PSU is removed from the chassis, the cooling module within is also
removed.
The subsystem is equipped with two (2), dual-speed, thermal fan, cooling
modules. They are installed in the rear section of the PSU modules. Two (2)
LEDs on the PSU faceplate indicate the corresponding cooling fan statuses.
Intelligent Dual Speed Operation
The cooling fans in the cooling module operate with two rotation speeds.
Under normal conditions, the cooling fans run at the low speed, which is
sufficient for maintaining airflow across components. Under the following
conditions, cooling fans raise their rotation speed to increase airflow:
1. Component Failure: once a cooling fan, a PSU, or a temperature
sensor fails, the remaining cooling fans automatically raise its
rotation speed.
2. Elevated Temperature: if the temperature reading breaches the
upper threshold set for any of the interior temperature sensors, the
cooling fans automatically raise its rotation speed.
