Description
● If the system is powered on and in good health, the indicator lights solid blue.
No corrective action is required.
● The indicator blinks amber if the system is on or in standby, and if any error
exists (For example, a failed fan). See the System Event Log or system
messages for the specific issue. For information about the event and error
messages generated by the system firmware and agents that monitor system
components, go to qrl.dell.com > Look Up > Error Code, type the error code,
and then click Look it up.Invalid memory configurations can cause a blank
screen or no video output. See the Getting help section.
The power-on indicator lights when the system powered on. The power button
controls the power supply output to the system.
NOTE: On ACPI-compliant operating systems, turning off the system using the
power button causes the system to perform a graceful shutdown before power
to the system is turned off.
The identification button on the front and back panels can be used to locate a
particular system within a rack. When one of these buttons is pressed, the
corresponding system identification button on the back flashes until one of the
buttons is pressed again.
Press the system identification button to turn the system ID on or off.
If the system stops responding during POST, press and hold the system ID button
for more than five seconds to enter BIOS progress mode.
To reset iDRAC (if not disabled in F2 iDRAC setup), press and hold the button for
more than 15 seconds.

Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The indicator shows whether
power is present or if a power fault has occurred.
NOTE: The 2400 W and 2000 W PSUs use a C20 connector.
Figure 5. AC PSU status indicator

Table 4. AC PSU status indicator codes
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 firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating
firmware. If firmware update is interrupted, the PSUs do not function.
Blinking green and turns
off
When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off.
This indicates a PSU mismatch with respect to efficiency, 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 PowerEdge servers 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 configuration to a
low output configuration or vice versa, you must turn off the system.
CAUTION: The 120 V AC PSU is not recommended for this system and using the same
can cause system throttling.
CAUTION: If two PSUs are used, they must be of the same type, operate from the
same line voltage, and have the same maximum output power.
Locating Service Tag of your system
Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code is and Service
Tag are found on the back of the system by pulling out the information tag. Alternatively, the information may be on a sticker on
the chassis of the system. This information is used by Dell EMC to route support calls to the appropriate personnel.

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:

● iDRAC user
● Microsoft Active Directory user
● Lightweight Directory Access Protocol (LDAP) user
If you have opted for secure default access to iDRAC, you must use the iDRAC secure default password available on the system
Information tag. If you have not opted for secure default access to iDRAC, then use the default user name and password –root
and ca lvi n. You can also log in by using your 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 username 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/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.
