After replacing the battery, restart the system. To reset system configuration, enter the system BIOS, then select Load Default Settings.
5.2.5 Common problems encountered while operating and using the system
1. The operating systems in following list do not support partitions larger than 2.2 TB in size. When installing these systems, make sure that the
size of each partition is less than 2.2 TB.
The list is as follows:
CentOS 7.5
Oracle Linux 7.5
2. When installing a Linux OS, turn off UTC time synchronization. Under a Linux OS, enabling UTC time synchronization can result in an 8-
hour time difference between BMC and Linux.
3. The BIOS setup menu is not displayed on full-screen. This is due to changes in terminal resolution when console redirection is enabled. To
display the BIOS setup menu on full screen, go to the Console Redirection Settings submenu and enable the Resolution 100x31 option for serial
port.
4. If the mouse mode is changed due to problems with the remote screen ratio, refresh the remote desktop or adjust the size of the iKVM
window to counter this problem.
5. When accessing the BMC with Firefox to edit system configuration, if a window with the option to "Prevent this page from creating
additional dialogs" pops up, do not check this option. The new configuration cannot be saved when this option is selected.
6. Before using the remote desktop tool (JViewer) to install an OS, do not enable KVM encryption and media encryption. Enabling KVM and
media encryption might compromise the performance of the operating system installed.
