Initial system setup and configuration
Topics:
•Setting up your sled
•iDRAC configuration
•Options to install the operating system
Setting up your sled
Complete the following steps to set up your sled:
Steps
1.Unpack the sled.
2.Remove the I/O connector cover from the sled connectors.
CAUTION: While installing the sled, ensure that it is properly aligned with the slot on the enclosure to prevent damage to the sled connectors.
3.Install the sled in the enclosure.
4.Power on the enclosure.
NOTE: Wait for the chassis to initialize before you press the power button.
5.Press the power button on the sled.
Alternatively, you can also power on the sled by using:
●The sled iDRAC. For more information, see the Log in to iDRAC section.
●Open Manage Enterprise modular (OME-modular), after the sled iDRAC is configured on the OME. For more information, see the OME-modular User’s Guide at www.dell.com/openmanagemanuals.
iDRAC configuration
The Integrated Dell Remote Access Controller (iDRAC) is designed to make system administrators more productive and improve the overall availability of Dell systems. iDRAC alerts administrators about system issues and enables them to perform remote system management. This reduces the need for physical access to the system.
Options to set up iDRAC IP address
You must configure the initial network settings based on your network infrastructure to enable the communication to and from iDRAC.
You can set up the IP address by using one of the following interfaces:

Log in to iDRAC
You can log in to iDRAC as:
●iDRAC user
●Microsoft Active Directory user
●Lightweight Directory Access Protocol (LDAP) user
If you have opted for secure default access to iDRAC, the iDRAC secure default password is available on the back of the system Information tag. If you have not opted for secure default access to iDRAC, then the default user name and password are root and calvin. You can also log in by using Single Sign-On or Smart Card.
NOTE: You must have the iDRAC credentials to log in to iDRAC.
NOTE: Ensure that you change the default user name and password after setting up the iDRAC IP address.
NOTE: The Intel® Quick Assist Technology (QAT) on the Dell EMC PowerEdge MX840c is supported with chipset integration and is enabled through an optional license. The license files are enabled on the sleds through iDRAC.
For more information about drivers, documentation, and white papers on the Intel® QAT, see https://01.org/intel- quickassist-technology.
For more information about logging in to the iDRAC and iDRAC licenses, see the latest Integrated Dell Remote Access Controller User's Guide at www.dell.com/poweredgemanuals
You can also access iDRAC by using RACADM. For more information, see the RACADM Command Line Interface Reference Guide at www.dell.com/poweredgemanuals

Drives
Drive installation guidelines
Drives are available in hot-swappable drive carriers that fit in the front drive slots of the PowerEdge MX840c sled.
CAUTION: Before attempting to remove or install a drive while the sled is running, see the documentation for the storage controller card to ensure that the host adapter is configured correctly to support hot-swap drive removal and insertion.
CAUTION: Do not power off or restart your sled while the drive is being formatted. Doing so can cause a drive failure.
When you format a drive, allow enough time for the formatting to be complete. Be aware that high-capacity drives can take a long time to format.
