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 screen to notify you of a possible problem with the system. Table1-8 lists the system messages that can occur and the
probable cause and corrective action for each message.

Table 1-8.SystemMessages
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See
your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
NOTE: If you receive a system message that is not listed in Table1-8, check the documentation for the application that is running when the message
appears or the operating system's documentation for an explanation of the message and recommended action.
Alert! Redundant memory disabled!
Memory configuration does not
support redundant memory.
Installed memory modules are not the same type
and size; faulty memory module(s).
Ensure that all memory modules are of the same type and
size and that they are properly installed. If the problem
persists, see Troubleshooting System Memory.
Attempting to update Remote
Configuration. Please wait...
Remote Configuration request has been detected
and is being processed.
Wait until the process is complete.
BIOS Update Attempt Failed!
Remote BIOS update attempt failed.
Retry the BIOS update. If the problem persists, see Getting
Help.
Caution! NVRAM_CLR jumper is
installed on system board.
NVRAM_CLR jumper is installed. CMOS has been
cleared.
Remove NVRAM_CLR jumper. See Figure6-1 for jumper
location.
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 Processors.
Decreasing available memory
Faulty or improperly installed memory modules.
See Troubleshooting System Memory.
DIMM pairs must be matched in size,
speed, and technology. The following
DIMM pair is mismatched: DIMM x and
DIMM y.
Mismatched or unmatched DIMMs installed; faulty
or improperly seated memory module(s).
Ensure that all pairs of memory modules are of the same type
and size and that they are properly installed. See System
Memory. If the problem persists, see Troubleshooting System
Memory.
DIMMs must be populated in
sequential order beginning with slot
1. The following DIMM is
electrically isolated: DIMM x.
The specified DIMM is inaccessible to the system
due to its location. DIMMs must be populated in
sequentialorder,beginningwithslot1.
Populate 2, 4, 8, or 12 DIMMs sequentially beginning with slot
1. See System Memory.
DIMMs should be installed in pairs.
Pairs must be matched in size,
speed, and technology.
Mismatched or unmatched DIMMs installed; faulty
or improperly seated memory module(s). The
system will operate in a degraded mode with
reduced ECC protection. Only memory installed in
channel 0 will be accessible.
Ensure that all pairs of memory modules are of the same type
and size and that they are properly installed. See System
Memory. If the problem persists, see Troubleshooting System
Memory.
Dual-rank DIMM paired with Single-
rank DIMM - The following DIMM/rank
has been disabled by BIOS: DIMM x
Rank y
Mismatched DIMMs installed; faulty memory
module(s). The system has detected a dual-rank
DIMM paired with a single-rank DIMM. The second
rank of the dual-rank DIMM will be disabled.
Ensure that all pairs of memory modules are of the same type
and size and that they are properly installed. See System
Memory. If the problem persists, see Troubleshooting System
Memory.
Error: Incorrect memory
configuration. DIMMs must be
installed in pairs of matched memory
size, speed, and technology.
Mismatched or unmatched DIMMs installed; faulty
or improperly seated memory module(s).
Ensure that all pairs of memory modules are of the same type
and size and that they are properly installed. See System
Memory. If the problem persists, see Troubleshooting System
Memory.
Error: Memory failure detected.
Memory size reduced. Replace the
faulty DIMM as soon as possible.
Faulty or improperly seated memory module(s).

Remote Access Controller initialization failure.
Ensure that the Remote Access Controller is properly
installed. See RAC Card.
FBD training error: The following
branch has been disabled: Branch x
The specified branch (channel pair) contains DIMMs
that are incompatible with each other.
Ensure that only Dell-qualified memory is used. Dell
recommends purchasing memory upgrade kits directly from
www.dell.com or your Dell sales agent to ensure
compatibility.
