13. If the system-board tray is installed in a chassis, remove it (see “Removing the
system-board tray from a 2U chassis” on page 75 or “Removing the
system-board tray from a 3U chassis” on page 77).
14. If an expansion enclosure is installed, remove it (see “Removing an expansion
enclosure from a system-board tray” on page 73); otherwise, remove the
system-board tray cover (see “Removing the system-board tray cover” on page
121).
15. Return the BIOS recovery jumper to pins 1 and 2.
16. Install the expansion enclosure, if you removed one (see “Installing an
expansion enclosure on a system-board tray” on page 74); otherwise, install
the system-board tray cover (see “Installing the system-board tray cover” on
page 122).
17. Install the system-board tray in the chassis (see “Installing the system-board
tray in a 2U chassis” on page 76 or “Installing the system-board tray in a 3U
chassis” on page 78).
18. Reconnect the external cables and power cords; then, turn on the attached
devices and turn on the system-board tray.
BMC system event log messages
The following tools are available to view the BMC system event log:
v Dynamic System Analysis (DSA) Preboot diagnostic programs. See “Running the
diagnostic programs” on page 32.
v
BIOS configuration utility program. See “Using the BIOS configuration utility
program” on page 156.
v Industry-standard Intelligent Platform Management Interface (IPMI) management
tools.
Domain A system-error log messages or sensor numbers refer to system-board
trays in the lower position in a 2U chassis. Domain B system-error log messages or
sensor numbers refer to system-board trays in the upper position.
The following table describes the possible system event log messages and
suggested actions to correct the detected problems.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v
See Chapter 3, “Parts listing,” on page 59 to determine which components are customer replaceable units
(CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
