Initial system setup and configuration for
PowerEdge C6525
Setting up the system
Perform the following steps to set up the system:
Steps
1. Unpack the system.
2. Install the system into the rack. For more information about installing the system into the rack, see the Rail Installation Guide on the
product page at www.dell.com/poweredgemanuals.
3. Connect the peripherals to the system and the system to the electrical outlet.
4. Power on the system by pressing the power button.
For more information about setting up the system, see the Getting Started Guide that is shipped with your system.
iDRAC configuration
The Integrated Dell Remote Access Controller (iDRAC) is designed to make you more productive as a system administrator and improve
the overall availability of Dell EMC servers. iDRAC alerts you to system issues, helps you to perform remote management, and reduces the
need for physical access to the system.
Options to set up iDRAC IP address
To enable communication between your system and iDRAC, you must first configure the network settings based on your network
infrastructure. The network settings option is set to DHCP, by default.
NOTE: For static IP configuration, you must request for it at the time of purchase.
You can set up the iDRAC IP address using one of the following interfaces. For information about how to set up iDRAC IP address, see the
documentation links provided in the table.

Options to log in to iDRAC
To log in into the iDRAC Web User Interface, open a browser and enter the address IP.
You can log in to iDRAC as:
• iDRAC user
• Microsoft Active Directory user
• Lightweight Directory Access Protocol (LDAP) user
In the login screen displayed, if you have opted for secure default access to iDRAC, enter the iDRAC secure default password available on
back side of the Information Tag. If you have not opted for secure default access to iDRAC, enter the default user name and password –
root and calvin. You can also log in by using your Single Sign-On or Smart Card.
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 www.dell.com/idracmanuals.
NOTE: To determine the most recent iDRAC release for your platform and for latest documentation version, see KB
article www.dell.com/support/article/sln308699.
You can also access iDRAC using command-line protocol - RACADM. For more information, see the iDRAC with Lifecycle Controller
RACADM CLI Guide available at www.dell.com/idracmanuals
You can also access iDRAC using automation tool - Redfish API. For more information, see the iDRAC9 with Lifecycle Controller Redfish
API Guide available at www.dell.com/idracmanuals
Resources to install operating system
If the system is shipped without an operating system, you can install a supported operating system by using one of the following
resources. For information about how to install the operating system, see the documentation links provided in the table.
