Replacing a Failed PSU Module

Figure 5-8: Remove the Cooling Module
WARNING!
• When a PSU is pulled out of the chassis, the fan module beneath the PSU is
removed from the chassis at the same time.
• Do not remove the PSU module unless a replacement is readily available.
Removing a PSU without a replacement will cause severe disruptions to the
internal airflow and the subsystem will overheat, possibly causing irreparable
damage to some of the subsystem components.
• It is recommended that the replacement procedure is completed in less than five (5)
minutes to prevent the subsystem from overheating.
Step 6. Remove the cooling module: To do this, push the clips on either side
of the module rear panel together. Then gently pull the cooling
module out of the lower level of the PSU bracket.
