3-14 Dell PowerEdge 2450 Systems Installation and Troubleshooting Guide
 


A warning message alerts you to a possible problem and asks you to take corrective
action before the system continues a task. For example, before you format a diskette,
a message may warn you that you may lose all data on the diskette, as a way to pro-
tect against inadvertently erasing or writing over the data. These warning messages
usually interrupt the procedure and require you to respond by typing
 (yes) or
(no).
NOTE: Warning messages are generated by either the application program or the
operating system. See Chapter 4, "Finding Software Solutions," and the documenta-
tion that accompanied the operating system and application program for more
information on warning messages.



When you run a test group or subtest in the Dell Diagnostics, an error message may
result. These particular error messages are not covered in this section. Record the
message on a copy of the Diagnostics Checklist (see Chapter 11, “Getting Help”), and
then follow the instructions in that section for obtaining technical assistance.



  
    
 
The Dell Hardware Instrumentation Package (HIP) server management application
program generates alert messages that appear in the Simple Network Management
Protocol (SNMP) trap log file. To see the trap log, select any enterprise under the
SNMP trap log icon. Alert log messages consist of information, status, warning, and
failure messages for drive, temperature, fan, and power conditions. More information
about the Alert Log window and options is provided in the Dell HIP online help and
the HP OpenView Network Node Manager (NNM) Special Edition (SE) With Dell
OpenManage HIP User's Guide.

If a redundant arrays of independent disks (RAID) controller such as the optional
PowerEdge Expandable RAID Controller (PERC) 3/Si controller is installed in the sys-
tem, three light-emitting diode (LED) indicators on each of the hard-disk drive carriers
provide information on the status of the SCSI hard-disk drives (see Table 3-1). The
SCSI backplane firmware controls the drive online and drive failure indicators.
