Dell PowerEdge 2650 - Manual (Page 13)

Solving Problems Described by LCD Status Messages
When a single message appears on the status LCD, locate the code in Table 3 -9 and perform the suggested corrective action. The code on the LCD can often
specify a very precise fault condition that is easily corrected. For example, if the code E0280 MISSING VRM 2 appears, you know that a microprocessor is
installed in socket 2, but the VRM for that microprocessor is either improperly installed or missing.
In contrast, you might be able to determine the problem if multiple related errors occur. For example, if you receive a series of messages indicating multiple
voltage faults, you might determine that the problem is a failing power supply.
Removing LCD Status Messages
For faults associated with sensors, such as temperature, voltage, fans, and so on, the LCD message is automatically removed when that sensor returns to a
normal state. For example, if temperature for a component goes out of range, the LCD displays the fault; when the temperature returns to the acceptable
range, the message is removed from the LCD. For other faults, you must take action to remove the message from the display:
l Clear the SEL — You can perform this task remotely, but you will lose the event history for the system.
l Chassis intrusion — When you remove the cover, the system assumes that you are servicing the bad component; the LCD clears when you replace the
cover.
l Power cycle — Turn off the system and disconnect it from the electrical outlet; wait approximately ten seconds, reconnect the power cable, and restart
the system.
Any of these actions will remove fault messages, and return the status indicators and LCD colors to the normal state. Messages will reappear under the
following conditions:
l The sensor returns to a normal state but fails again, resulting in a new SEL entry.
l The system is reset and new error events are detected.
l A failure is recorded from another source that maps to the same display entry.
System Messages
System messages appear on the console during POST to notify you of a possible problem with the system. If you are performing console redirection, system
messages will appear on the remote console.
Table 3 -10 lists the system messages that can occur and the probable cause for each message.
EFFF0 RAC ERROR Remote access controller firmware failure;
faulty system board. Replace the expansion-card riser board (see " Expansion-Card Riser Board ").
EFFF1 POST ERROR BIOS error. Update the BIOS firmware. Download the latest firmware from the Dell | Support
website at support.dell.com.
EFFF2 BP ERROR Faulty or improperly installed backplane
board. Ensure that the interface cables are securely connected to the SCSI backplane board.
If the problem persists, replace the backplane board (see "
SCSI Backplane Board ").
NOTE: If you receive a system message that is not listed in Table 3 -10 , check the documentation for the application program that is running when the
message appears or the operating system's documentation for an explanation of the message and recommended action.
Table 3-10. System Messages
Message Causes Corrective Actions
Address mark not found Faulty CD/diskette drive
subsystem or hard-drive
subsystem; faulty system board. Replace the faulty drive(s) (see " CD and Diskettes Drives " and " Hard
Drives "). If the problem persists, replace the system board (see " System
Board ").
Alert! Current configuration does not
support redundant memory. Redundant
memory is disabled.
Memory modules installed are not
the same type and size in all
banks; faulty memory module(s). Ensure that all banks contain memory modules of the same type and
size and that they are properly installed. If the problem persists, replace
the faulty memory module(s) (see "
Memory Modules ").
Alert! Unsupported memory or incomplete
sets in the following bank(s): Bank n
Memory modules installed in the
specified bank are not the same
type and size; faulty memory
module(s).
Amount of available memory limited to 256
MB!
OS Install Mode is enabled in the
System Setup program. Disable OS Install Mode in the System Setup program (see " Using the
System Setup Program ").
Auxiliary device failure Loose or improperly connected
mouse or keyboard cable; faulty
mouse or keyboard. Check the mouse and keyboard cables and connectors. If the problem
persists, replace the mouse and keyboard. If the problem persists,
replace the system board (see "
System Board ").
BIOS Update Attempt Failed! Remote BIOS update attempt
failed. Retry the BIOS update. Download the latest firmware from the
Dell | Support website at
support.dell.com.
CD-ROM drive not found Improperly connected or missing
CD drive. Ensure that the CD drive is properly installed. If the problem persists,
replace the CD drive (see "
CD and Diskettes Drives ").
CPUs with different cache sizes detected Microprocessors with different
cache sizes are installed. Ensure that all microprocessors have the same cache size and that they
are properly installed (see "
Microprocessors ").
Decreasing available memory Faulty or improperly installed
memory modules. Ensure that the memory modules are properly installed. If the problem
persists, replace the faulty memory module(s) (see "
Memory Modules ").
Diskette drive n seek failure Incorrect configuration settings in
the System Setup program. Run the System Setup program to correct the settings (see " Using the
System Setup Program ").
Faulty or improperly installed
diskette drive. Ensure that the diskette drive is properly installed. If the problem
persists, replace the diskette drive (see "
CD and Diskettes Drives ").
