– System MAC Addresses
Select this choice to set and view the MAC addresses for the Ethernet
controllers on the blade server.
v Date and Time
Select this choice to set the system date and time, in 24-hour format
(hour:minute:second).
v System Security
Select this choice to set a power-on password. See "Using passwords" on page
42 for more information about passwords.
v Start Options
Select this choice to view or change the start options. Changes in the start
options take effect when you start the blade server.
– Startup Sequence Options
Select this choice to view the startup device sequence that is set for the blade
server.
Note: To set the startup sequence, which is the order in which the blade
server checks devices to find a boot record, you must use the
management-module Web interface.
You can set keyboard operating characteristics, such as whether the blade server
starts with the keyboard number lock on or off. You can enable the blade server
to run without a diskette drive or keyboard.
You can enable or disable the PXE option for either of the integrated Gigabit
Ethernet controllers. The default setting is Planar Ethernet 1, which enables the
PXE option for the first Ethernet controller on the system board.
If you enable the boot fail count, the BIOS default settings will be restored after
three consecutive failures to find a boot record.
You can enable a virus-detection test that checks for changes in the boot record
when the blade server starts.
This choice is on the full Configuration/Setup menu only.
v Advanced Setup
Select this choice to change settings for advanced hardware features.
Important: The blade server might malfunction if these options are incorrectly
configured. Follow the instructions on the screen carefully.
– Memory Settings
Select this choice to manually enable a pair of memory connectors.
If a memory error is detected during POST or memory configuration, the blade
server automatically disables the failing memory pair of memory connectors
and continues operating with reduced memory. After the problem is corrected,
you must enable the memory connectors. Use the arrow keys to highlight the
pair of memory connectors that you want to enable, and use the arrow keys to
select Enable.
To maintain optimum system operation in the event of a memory failure, you
can set the Memory Configuration for memory Mirroring or Sparing.
Memory mirroring stores duplicate data on two DIMMs to prevent data loss if
a DIMM fails. Memory sparing removes the failed memory from the system
configuration and activates a Hot Spare Memory pair of DIMMs to replace the
failed memory pair of DIMMs. Before you can enable the memory mirroring or
sparing, at least two pairs of identical DIMMs must be installed in the blade
