3.12 Installing and Removing Power Supply Units
The IQH3A 3U Enclosure is provided with one PSU as standard. There is an option for
installing a second PSU to allow dual redundant operation. This may be a factory fitted option
or can be done as an upgrade.
When installing a second PSU ensure that the blanking plate is kept in the storage position.
