LCD panel

The LCD panel provides system information, status, and error messages to indicate if the system is functioning correctly or requires
attention. The LCD panel can also be used to congure or view the system’s iDRAC IP address. 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.com.

The LCD panel is available only on the optional front bezel. The optional front bezel is hot pluggable.

The statuses and conditions of the LCD panel are outlined here:

• The LCD backlight is white during normal operating conditions.

• When the system needs attention, the LCD backlight turns amber, and displays an error code followed by descriptive text.

NOTE

: If the system is connected to a power source and an error is detected, the LCD turns amber regardless of whether the

system is turned on or o.

• When the system turns o and there are no errors, LCD enters the standby mode after ve minutes of inactivity. Press any button on
the LCD to turn it on.

• If the LCD panel stops responding, remove the bezel and reinstall it.
If the problem persists, see Getting help.

• The LCD backlight remains o if LCD messaging is turned o using the iDRAC utility, the LCD panel, or other tools.

CAUTION: Do not disconnect the power cable, or unplug

the PSU when updating rmware. If rmware update is
interrupted, the PSUs do not function.

Blinking green and turns o When hot-plugging a PSU, the PSU handle blinks green ve times

at a rate of 4 Hz and turns o. This indicates a PSU mismatch
concerning eciency, 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 on the system.

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 conguration to a low output conguration or
conversely, you must turn o the system.

CAUTION: AC PSUs support both 240 V and 120 V input

voltages except for Titanium PSUs, which support only
240 V. When two identical PSUs receive dierent input
voltages, they can output dierent wattages, and trigger a
mismatch.

CAUTION: If two PSUs are used, they must be of the

same type and have the same maximum output power.

Using system diagnostics

If you experience a problem with your system, run the system diagnostics before contacting Dell for technical assistance. The purpose of
running system diagnostics is to test your system hardware without using additional equipment or risking data loss. If you are unable to x
the problem yourself, service and support personnel can use the diagnostics results to help you solve the problem.
