Icon Indicator, button,

Description
NOTE: On APCI-compliant operating system, turning o the system using
power button causes the system to perform a graceful shutdown before power
to the system is turned o.
Health indicator Indicates the health of the system.
• 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 specic
issue. For information about the event and error messages generated by the system
rmware and agents that monitor system components, see the Error Code Lookup
page at qrl.dell.comInvalid memory congurations can cause a blank screen or no
video output. See the Getting help section.
System
identication
button
The identication 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
identication button on the back ashes until one of the buttons is pressed again.
Press the system identication button to turn the system ID on or o.
If the system stops responding during POST, press and hold the system ID button for
more than ve 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.
NIC indicator codes
Each NIC on the back panel has an indicator that provides information about the network activity and link status. The activity LED indicates
whether the NIC is connected or not. The link LED indicates the speed of the connected network.

Table 9. NIC indicators
Convention Status Condition
A Link and activity indicators are o. The NIC is not connected to the network.
B Link indicator is green. The NIC is connected to a valid network at its maximum
port speed (1 Gbps or 10 Gbps).
C Link indicator is amber. The NIC is connected to a valid network at less than its
maximum port speed.
D Activity indicator is ashing green. Network data is being sent or received.
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 a power fault has occurred.

pattern
Condition
A Green A valid power source is connected to the PSU and the PSU is operational.
B Flashing green When the rmware of the PSU is being updated, the PSU handle ashes green.
CAUTION: Do not disconnect the power cable or unplug the PSU when updating
rmware. if rmware update is interrupted, the PSUs do not function.
Technical specications 17

Convention Power indicator
pattern
Condition
C Flashing green and
turns o.
When hot-adding a PSU, the PSU handle ashes green ve times at 4 Hz rate and turns
o. This indicates a PSU mismatch with respect to eciency, feature set, health status,
and supported voltage.
CAUTION: If four PSU are installed, the four PSUs must have the same type of
label; for example, Extended Power Performance (EPP) label. Mixing PSU from
previous generations of PowerEdge servers is not supported, even if the PSU
has 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 PSU with the blinking
indicator. Swapping the PSU to make matched pair can result in an error
condition and unexpected system shutdown. To change from a high output
conguration to a low output conguration or vice versa, you must turn o the
system
CAUTION: The 120 V AC PSU is not recommended for this system. Operating at
120 V AC results in the 2400W PSU de-rating to only 1400W, which can aect
power redundancy policy and possibly system throttling.
CAUTION: If four PSUs are used, they must be of the same type and have the
same maximum output power.
D Flashing amber Indicates a problem with the PSU.
E Not illuminated Power is not connected to the PSU.

Initial system setup and conguration
Setting up your system
Complete the following steps to set up your system:
1 Unpack the system.
2 Install the system into the rack.
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 conguration
The Integrated Dell Remote Access Controller (iDRAC) is designed to make system administrators more productive and improve the overall
availability of Dell EMC 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 congure 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 congure 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:
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.
Log in to iDRAC
You can log in to iDRAC as:
• iDRAC user
• Microsoft Active Directory user
• Lightweight Directory Access Protocol (LDAP) user
The default user name and password are root and calvin. You can also log in by using Single Sign-On or Smart Card.
NOTE: You must have 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.

Initial system setup and conguration 19

Pre-operating system management applications
You can manage basic settings and features of a system without booting to the operating system by using the system rmware.
Options to manage the pre-operating system
applications
Your system has the following options to manage the pre-operating system applications:
• System Setup
• Dell EMC Lifecycle Controller
• Boot Manager
• Preboot Execution Environment (PXE)
System Setup
By using the System Setup screen, you can congure the BIOS settings, iDRAC settings and device settings of your system.
NOTE: Help text for the selected eld is displayed in the graphical browser by default. To view the help text in the text browser,
press F1.
You can access system setup by using two methods:
• Standard graphical browser — The browser is enabled by default.
• Text browser — The browser is enabled by using Console Redirection.
Viewing System Setup
To view the System Setup screen, perform the following steps:
1 Turn on, or restart your system
2 Press F2 immediately after you see the following message:
F2 = System Setup
NOTE: If your operating system begins to load before you press F2, wait for the system to nish booting, and then
restart your system and try again.
System Setup details
The System Setup Main Menu screen details are explained as follows:
Option Description
System BIOS Enables you to congure BIOS settings.
iDRAC Settings Enables you to congure iDRAC settings.
