5.5 Error 
Reporting 
This section documents the types of system bus error conditions monitored by the SE7501WV2 
board set. 
5.5.1 
Error Sources and Types 
One of the major requirements of server management is to correctly and consistently handle 
system errors. System errors on the SE7501WV2, which can be disabled and enabled 
individually, can be categorized as follows: 
• 
PCI bus errors 
• 
Processor bus errors 
• 
Memory single- and multi-bit errors 
• 
General Server Management sensors 
On the SE7501WV2 platform, the general server management sensors are managed by the 
Sahalee BMC. 
5.5.2 
PCI Bus Errors 
The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and 
system errors, respectively. In the case of PERR#, the PCI bus master has the option to retry 
the offending transaction, or to report it using SERR#. All other PCI-related errors are reported 
by SERR#. SERR# is routed to NMI if enabled by BIOS.  
5.5.3 Intel
®
 Xeon™ Processor Bus Errors 
The MCH supports the data integrity features supported by the Xeon bus, including address, 
request, and response parity. In addition, the MCH can generate BERR# on unrecoverable 
errors detected on the processor bus. Unrecoverable errors are routed to an NMI by the BIOS. 
5.5.4 
Memory Bus Errors 
The MCH is programmed to generate an SMI on single-bit or double-bit data errors in the 
memory array if ECC memory is installed. The MCH performs the scrubbing. The SMI handler 
records the error and the DIMM location to the system event log.  
5.5.5 
Fault and Status LEDs 
The SE7501WV2 server board uses system fault/status LEDs in many areas of the board. 
There are fault LEDs for the memory DIMMs, the fan headers, and the processors. There are 
also status LEDs for 5-volt stand-by and system status indication. A blue LED is provided as a 
system ID LED. When the error reporting system determines there is a problem with any device, 
it will light the LED of the failing component. In the event of a power switch power down or loss 
of AC, the status of all baseboard fault LEDs will be remembered and restored by BMC when 
AC is restored. Fault LEDs will only be reset when a Front Panel Reset is performed with main 
power available to the system or under control of an IPMI command.
