CAUTION
Excessive temperatures could damage system components.
â–¶
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
using the iRMC web interface. Y
our configuration is now non-redundant.
The CSS error is only an information. After removing the PSU out of its
bay, the CSS error will be cleared automatically.
