Locating the Service Tag of your system
You can identify your system using the unique Express Service Code and Service Tag. Pull out the information tag in front of the system to
view the Express Service Code and Service Tag. Alternatively, the information may be on a sticker on the chassis of the system. The mini
Enterprise Service Tag (EST) is found on the back of the system. This information is used by Dell to route support calls to the appropriate
personnel.

Options to set up iDRAC IP address
iDRAC conguration
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 to system issues, helps them perform remote system management, and reduces the
need for physical access to the system.
Options to set up iDRAC IP address
You must congure the initial network settings based on your network infrastructure to enable the communication to and from iDRAC.
NOTE: For static IP conguration, you must request for it at the time of purchase.
You must use the default iDRAC IP address 192.168.0.120 to congure the initial network settings, including setting up DHCP or a static IP
for iDRAC.
This option is set to DHCP by Default. You can set up the IP address by using one of the following interfaces:

NOTE: To access iDRAC, ensure that you connect the ethernet cable to the dedicated NIC port. You can also access iDRAC
through the shared LOM mode, if you have opted for a system that has the shared LOM mode enabled.
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.
For more information about logging in to the iDRAC and iDRAC licenses, see the latest Integrated Dell Remote Access Controller User's
Guide at Dell.com/idracmanuals.
You can also access iDRAC by using RACADM. For more information, see the RACADM Command Line Interface Reference Guide at
Dell.com/idracmanuals.
