PERC 2/DC BIOS Error Messages
PERC 2/DC BIOS messages alert you to possible hardware problems. See the Dell
PowerEdge Expandable RAID Controller 2/DC User’s Guide on the Dell PowerVault
735N Resource CD for a list of these messages.
System Beep Codes
NOTE: If the system boots without a keyboard, mouse, or monitor attached, the sys-
tem will not issue beep codes related to these peripherals.
When an error that cannot be reported on the monitor occurs during a boot routine,
the system may emit a series of beeps that identify the problem. The beep code is a
pattern of sounds; for example, one beep followed by a second beep and then a burst
of three beeps (code 1-1-3) means that the system was unable to read the data in non-
volatile random-access memory (NVRAM). This information is valuable to the Dell
technical support representative if you need to call for technical assistance.
When a beep code is emitted, record it on a copy of the Diagnostics Checklist in
Chapter 9, “Getting Help,” and then look it up in Table 3-2. If you are unable to resolve
the problem by looking up the meaning of the beep code, use the Dell Diagnostics to
identify a more serious cause. If you are still unable to resolve the problem, see Chap-
ter 9, “Getting Help,” for instructions on obtaining technical assistance.
