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.
