Removing and Installing the Power

Supply/Cooling Fan Module

CAUTION: Only trained service technicians are authorized to remove the system

cover and access any of the components inside the system. Before you begin this

procedure, review the safety instructions that came with the system.

Your enclosure supports two separate modules containing an integrated power

supply and four cooling fans. While the enclosure can operate temporarily

with only one functional power supply, both cooling modules (with four fans

each) must be present for proper cooling. Seven of the eight individual fans

must be operational to avoid overheating of the enclosure.

NOTICE: A single power supply/cooling module can be removed from a powered-

on enclosure for a maximum period of 5 minutes. Beyond that time, the enclosure

may automatically shut down to prevent damage.
