LCD panel
The LCD panel provides system information, status, and error messages to indicate if the system is functioning correctly or requires
attention. The LCD panel can also be used to configure or view the system’s iDRAC IP address. For information about the event and error
messages generated by the system firmware and agents that monitor system components, see the Error Code Lookup page at
qrl.dell.com.
The statuses and conditions of the LCD panel are outlined here:
• The LCD backlight is white during normal operating conditions.
• When the system needs attention, the LCD backlight turns amber, and displays an error code followed by descriptive text.
NOTE: If the system is connected to a power source and an error is detected, the LCD turns amber regardless of
whether the system is turned on or off.
10 PowerEdge R940xa system overview

• When the system turns off and there are no errors, LCD enters the standby mode after five minutes of inactivity. Press any button on
the LCD to turn it on.
• If the LCD panel stops responding, remove the bezel and reinstall it.
If the problem persists, see Getting help.
• The LCD backlight remains off if LCD messaging is turned off using the iDRAC utility, the LCD panel, or other tools.

Locating the information 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 back of the system chassis.
The mini Enterprise Service Tag (EST) is found on the back of the system chassis. This information is used by Dell to route support calls to
the appropriate personnel.

4. iDRAC MAC address and iDRAC secure password label
NOTE: 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. This label will be blank, if you have not opted for secure default access to
iDRAC, then the default user name and password are root and calvin.

Initial system setup and configuration
Setting up your system
Perform the following steps to set up your 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 at
www.dell.com/poweredgemanuals.
3. Connect the peripherals to the system.
4. Connect the system to its electrical outlet.
5. Power on the system by pressing the power button or by using iDRAC.
6. Power on the attached peripherals.
For more information about setting up your system, see the Getting Started Guide that shipped with your system.
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
To enable communication between your system and iDRAC, you must first configure the network settings based on your network
infrastructure.
NOTE: For static IP configuration, you must request for it at the time of purchase.
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 iDRAC9 dedicated network 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.
