Update Firmware for Management Consoles Without Servers
Downtime
You can update firmware for management consoles for CMC, iDRAC and Lifecycle Controller without downtime on the servers:
1. In a scenario, where both the primary and the standby CMC is present, you can update the CMC firmware without servers or
IOMs downtime.
2. To update firmware on the primary CMC, see the Updating Firmware section.
When you update firmware on the primary CMC, the standby CMC takes on the role of the primary CMC. Hence, IOMs and
servers downtime does not occur.
NOTE: The firmware update process impacts only the management consoles of IOM and iDRAC servers. There is no
impact on the external connectivity between the servers and IOMs.
3. To update iDRAC or Lifecycle Controller firmware without a downtime of chassis, perform the update using the Lifecycle
Controller service. For information on updating server component firmware using Lifecycle Controller, see the Upgrading
Server Component Firmware section.
NOTE: While updating any other components such as Mezzanine cards, NDC controllers, and BIOS, a downtime of
the servers occurs.
Extended Power Performance Scenarios - Using Web Interface
Scenario 1: When EPP is enabled with 3000W PSU:
• The following options in the Web interface are grayed out and not available for selection:
– Server Based Power Management (SBPM).
– Redundancy Policy: Power Supply Redundancy and No Redundancy.
– Server Performance Over Power Redundancy (SPOPR).
– Dynamic Power Supply Engagement (DPSE).
– Allow 110 VAC Operation.
• Changing the System Input Power Cap value to less than or equal to 13300 W, displays the following message:
System Input Power Cap cannot be set to less than or equal to 13300 W (45381 BTU/h)
while Extended Power Performance is enabled.
• Selecting the check box to enable Max Power Conservation Mode (MPCM) displays the following message:
Enabling Max Power Conservation Mode will deactivate Extended Power Performance. Max
Power Conservation Mode option will force servers into a low power, limited performance
mode and disable server power up. Press OK to continue.
Scenario 2: When EPP is disabled with 3000W PSU:
• The following options in the Web interface are grayed out and not available for selection:
– Server Performance Over Power Redundancy (SPOPR).
– Allow 110 VAC Operation.
• Selecting the check box to enable Server Based Power Management (SBPM), displays the following message:
Checking the Server Based Power Management Mode option will set your power cap to max
value, server priorities to default priority, and disables Max Power Conservation Mode.
Are you sure you want to continue?
• Selecting the check box to enable Max Power Conservation Mode (MPCM), displays the following message:
Enabling Max Power Conservation Mode option will force servers into a low power, limited
performance mode and disable server power up. Press OK to continue.
Scenario 3: The EPP option is grayed out and not available for selection, if:
• EPP is disabled with 3000W PSUs, and any of the following power settings is enabled:
