The system's LCD panel provides system information, status, and error messages to indicate if the system is operating correctly or needs attention.
The LCD backlight lights are blue during normal operating conditions. When the system needs attention, the LCD lights are amber and display an error code followed by descriptive text.
Note: When the system connects to a power source and if it detects an error, the LCD lights amber regardless of whether the system is on or off.
The LCD backlight turns OFF when the system is in standby mode. It can turn on by pressing the LCD panel's Select, Left, or Right buttons.
The LCD backlight remains OFF if LCD messaging is off through the iDRAC utility, the LCD panel, or other tools.

Table 2. Status LED Indicators and Descriptions
LED Panel Description
The health indicator indicates the health status of the system.
Solid blue - Indicates that the system is powered on, is healthy, and system ID mode is not active.
Blinking blue - Indicates that the system ID mode is active. Press the system health and system ID button to switch to system health mode.
Solid amber - Indicates that the system is in fail-safe mode.
Blinking amber - Indicates that the system is experiencing a fault. Check the System Event Log for specific error messages.
The indicator turns solid blue if the system is on and in good health. The indicator flashes amber if the system is on or on standby and any issue occurs (for example, a failed fan or drive).

Condition
Corrective Action
Drive Indicator
The indicator turns solid amber if there is a drive error.
Check the System Event Log to determine if the drive has an error.
Run the appropriate Online Diagnostics test. Restart the system and run embedded diagnostics (ePSA).
Restart the system and enter the host adapter's configuration utility program when the drives are configured in a RAID array.
Temperature Indicator
The indicator turns solid amber if the system experiences a thermal error (for example, the ambient temperature is out of range or there is a fan failure).
Ensure that none of the following conditions exist:
A cooling fan has been removed or has failed.
The system cover, air shroud, memory module blank, or back filler bracket is not there.
The ambient temperature is too high.
The system obstructs the external airflow.
Electrical Indicator
The indicator turns solid amber if the system experiences an electrical error (for example, voltage out of range or a failed power supply unit (PSU) or voltage regulator).
Check the System Event Log or system messages for the specific issue. If it is due to a problem with the PSU, check the LED on the PSU. Reseat the PSU.
Memory Indicator
The indicator turns solid amber if a memory error occurs.
Check the System Event Log or system messages for the location of the failed memory. Reseat the memory module.
PCIe Indicator
The indicator turns solid amber if a PCIe card experiences an error.
Restart the system. Update any required drivers for the PCIe card. Reinstall the card.
iDRAC Direct LED Indicator Codes
The iDRAC Direct LED indicator indicates that the port is connected and part of the iDRAC subsystem.
You can configure iDRAC Direct using a USB to micro USB (type AB) cable to connect to your laptop or tablet. The following table describes iDRAC Direct activity when the iDRAC Direct port is active.
The iDRAC Direct LED indicator codes table describes the iDRAC status when it is solid green, flashing green, and turned off.

Condition
Solid green for two seconds.
Indicates that the laptop or tablet is connected.
Flashing green (on for two seconds and off for two seconds).
Indicates that the laptop or tablet connection is recognized.
LED indicator off
Indicates that the laptop or tablet is unplugged.
NIC Indicator Codes
Each NIC on the back of the system has indicators that provide information about the activity and link status. The activity LED indicator indicates if data is flowing through the NIC, and the link LED indicator indicates the speed of the connected network.

Condition
Link and activity indicators are off.
The NIC is not on the network.
The link indicator is green, and the activity indicator is blinking green.
The NIC is on a valid network at maximum port speed, and data is being sent or received.
The link indicator is amber, and the activity indicator is blinking green.
The NIC is on a valid network at less than its maximum port speed, and data is being sent or received.
The link indicator is green, and the activity indicator is off.
The NIC is on a valid network at maximum port speed, and data is not being sent or received.
The link indicator is amber, and the activity indicator is off.
The NIC is on a valid network at less than its maximum port speed, and data is not being sent or received.
The link indicator is blinking green, and the activity is off.
NIC identity is enabled through the NIC configuration utility.
Power Supply Unit Indicator Codes
AC power supply units (PSUs) have an illuminated translucent handle that is an indicator. The indicator shows whether power is present or if a power fault has occurred.

Power Indicator Codes
Condition
Green
The PSU connects to a valid power source, and the PSU is operational.
Blinking amber
Indicates a problem with the PSU.
Not illuminated
The PSU does not have power.
Blinking green
The PSU handle blinks green through the firmware update.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating the firmware. If the 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. It indicates a PSU mismatch concerning efficiency, feature set, health status, or supported voltage.
CAUTION: If the system has two PSUs, both PSUs must have the same type of label; for example, an 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 or failure to turn the system on.
CAUTION: Replace only the PSU with the blinking indicator when correcting a PSU mismatch. Swapping the PSU to make a matched pair can result in an error condition and unexpected system shutdown. You must turn off the system to change from a high output configuration to a low output configuration or vice versa.
CAUTION: AC PSUs support 240 V and 120 V input voltages, except for Titanium PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they can output different wattages and trigger a mismatch.
CAUTION: If the system has two PSUs, they must be the same type and have the same maximum output power.
