Hints, Tips, and Frequently Asked Questions for the xSeries 440:Quick Reference
Nonmaskable Interrupts (NMI)
What should be done if the system reports an NMI error and the system
restarts or displays an NMI error on the Light Path Diagnostic panel?
If an NMI occurs, use the following steps to help identify the failing component:
1.
View the System Error Log.
2.
Check the PCI and MEM LEDs.
•
If a PCI LED is on, a failing PCI/PCI-X adapter or board could be the problem.
•
If a MEM LED is on, check the DIMM error LEDs on the SMP Expansion
Module boards. If there is a DIMM failure, an LED will identify the failing
DIMM. Be sure to check the boards in both the lower and upper SMP
Expansion Modules, if installed. The problem might stem from a failing DIMM
or SMP board.
Important: Your server is designed so that any illuminated LEDs can be
illuminated again after ac power is removed. You have up to 12 hours to use
the Light Path Diagnostic LEDs after removing ac power from the server. After
12 hours, you must turn on the server again to be able to use the Light Path
Diagnostic LEDs to help locate system problems.
Complete the following steps to view the LEDs after removing ac power from
the server:
a.
Turn off the server and all peripheral devices.
b.
Press and hold the Light Path Diagnostics (blue) button on the diagnostics
panel. The LEDs will light while you press the switch.
Note: You can illuminate the LEDs for a maximum of two minutes. After
that time, the circuit that powers the LEDs is exhausted.
3.
Restart the server.
PCI scan order
For information about installing a ServeRAID adapter in a server that has a
PCI-X slot
enabled for high scan (boot) priority,
see “ServeRAID adapters and programs” on page
What is the PCI scan order for the xSeries 440 server?
The PCI scan order for systems with selectable slot priority (boot) is as follows: first
the integrated devices are scanned; then, PCI slots 1, 2, 6, 5, 3, and 4.
What is the PCI scan order for the xSeries 440 when an RXE-100
Expansion Enclosure is attached?
If an RXE-100 enclosure is attached to an xSeries 440 server, the scan order is as
follows: first the xSeries 440 integrated devices; then, the xSeries 440 PCI slots 1, 2,
6, 5, 3, and 4; then, the RXE-100 PCI slots 11, 12, 9, 10, 7, 8, 17, 18, 15, 16, 13, and
14.
