CAUTION
Excessive temperatures could damage system components.

Never leave the bay for the hot-plug PSU empty for more than two
minutes during operation.
If a hot-plug PSU should be removed from a redundant configuration,
while the system is in operation, proceed the following:
Disconnect the power cord from the dedicated PSU, see
"Disconnecting the power cord" on page 47 .
A CSS error is detected and the message "redundancy lost" is displayed
