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.

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.

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

Topics:

• Setting up your system

•

iDRAC configuration

• Options to set up iDRAC IP address

• Log in to iDRAC

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.

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.

18 Initial system setup and configuration

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.
