indicator, power

button

The power-on indicator lights when the system powered on. The power button controls

the power supply output to the system.

NOTE: On APCI-compliant operating system, turning off the system using

power button causes the system to perform a graceful shutdown before

power to the system is turned off.

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

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.

System

identification

button

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.

Technical specifications 15

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.

Figure 7. NIC indicators

Convention Status Condition

A Link and activity indicators are off. 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 flashing 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 firmware of the PSU is being updated, the PSU handle flashes green.

CAUTION: Do not disconnect the power cable or unplug the PSU when

updating firmware. if firmware update is interrupted, the PSUs do not

function.

C Flashing green and

turns off.

When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz rate and turns

off. This indicates a PSU mismatch with respect to efficiency, 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 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. Operating

at 120 V AC results in the 2400W PSU de-rating to only 1400W, which can

affect 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 configuration

Setting up your system

Complete the following steps to set up your system:

Steps

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.

Results

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 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 configure 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 configure 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.

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.
