Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator.
The DC PSUs have an LED that serves as an indicator.
The indicator shows whether power is present or if a power fault has occurred.

Power indicator codes Condition
Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the rmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating rmware. If
rmware update is interrupted, the PSUs do not function.
Blinking green and turns o When hot-plugging a PSU, the PSU handle blinks green ve times at a rate of 4 Hz and turns o. This
indicates a PSU mismatch with respect to eciency, feature set, health status, or supported voltage.
CAUTION: If two PSUs are installed, both the PSUs must have the same type of label; for
example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations of
XC Series Appliance and XC Core System is not supported, even if the PSUs have the same
power rating. This results in a PSU mismatch condition or failure to turn the system on.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking indicator.
Swapping the PSU to make a matched pair can result in an error condition and unexpected
system shutdown. To change from a high output conguration to a low output conguration or
vice versa, you must turn o the system.
CAUTION: AC PSUs support both 240 V and 120 V input voltages with the exception of Titanium
PSUs, which support only 240 V. When two identical PSUs receive dierent input voltages, they
can output dierent wattages, and trigger a mismatch.
CAUTION: If two PSUs are used, they must be of the same type and have the same maximum
output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.

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 EMC to route support calls to the
appropriate personnel.

Setting up your system
Complete the following steps to set up your system:
1 Unpack the system.
2 Install the system into the rack. For more information about installing the system into the rack, see Rail Installation Guide at Dell.com/
XCSeriesmanuals.
3 Connect the peripherals to the system.
4 Connect the system to its electrical outlet.
5 Turn the system on by pressing the power button or by using iDRAC.
6 Turn on the attached peripherals.
For more information about setting up your system, see the Getting Started Guide that shipped with your system.
iDRAC conguration
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 congure the initial network settings based on your network infrastructure to enable the communication to and from iDRAC.
You must use the default iDRAC IP address 192.168.0.120 to congure the initial network settings, including setting up DHCP or a static IP
for iDRAC. You can set up the IP address by using one of the following interfaces:

(optional)
NOTE: To access iDRAC, ensure that you connect the Ethernet cable to the iDRAC direct 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.
See Dell Integrated Dell Remote Access Controller User's Guide at Dell.com/idracmanuals
Log in to iDRAC
You can log in to iDRAC as:
• iDRAC user
• Microsoft Active Directory user
• Lightweight Directory Access Protocol (LDAP) user
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.
