CAUTION!

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 sub- system 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) min- utes to prevent the subsystem from overheating.
5.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. (See Figure 6.5)

6.Reinstall the cooling module into the new PSU module: To do this, align the cooling mod- ule with the lower level of the PSU bracket and gently slide the cooling module in.
