6. Under Enable IPMI over LAN, select or clear the check box next to the server to enable or disable IPMI over LAN.

Setting The First Boot Device For Servers
The First Boot Device page allows you to specify the boot device for each blade. You can set the default boot device and
also set a one-time boot device. This allows you to boot using a special image to perform tasks such as running
diagnostics or reinstalling an operating system.
To set the first boot device for some or all servers in the chassis:
1. Log in to the CMC web-based interface.
2. Click Servers in the system tree and then click Setup → Deploy First Boot Device. A list of servers is displayed, one
per row.
3. Select the boot device you want to use for each server from the list box.
4. If you want the server to boot from the selected device every time it boots, clear the Boot Once check box for the
server.
If you want the server to boot from the selected device only on the next boot cycle, select the Boot Once check box
for the server.
5. Click Apply.
Configuring And Managing Power
You can use the web-based and RACADM interfaces to manage and configure power controls on the CMC, as outlined
in the following sections. For more information on the various power management options, see the CMC User’s Guide at
support.dell.com/manuals.
The CMC’s power management service optimizes power consumption for the entire chassis (the chassis, servers, I/O
modules, iKVM, CMC, and PSUs) and re-allocates power to different modules based on the demand.
NOTE: To perform power management actions, you must have Chassis Control Administrator privileges.
1. Log in to the CMC web-based interface.
2. Select Chassis in the system tree.
3. Click the Power Management tab. The Power Budget Status page is displayed.
4. Click the Configuration sub-tab. The Budget/Redundancy Configuration page is displayed.
5. Configure the power budget and redundancy settings based on the components in the enclosure and your needs.
6. Click Apply to save your changes.
Installing Or Updating The CMC Firmware
NOTE: It is normal for some or all of the fan units to spin at 100 percent during CMC or iDRAC firmware updates on
a server.
NOTE: In a redundant CMC configuration, care must be taken to update CMC firmware on both modules. Failure to
do so may cause unexpected behavior during a CMC failover or failback. Use the following procedure for
redundant CMC deployments.
