Cannot wake server using Wake on LAN
Complete the following steps until the problem is resolved:
1. If you are using the dual-port network adapter and the server is connected to the network using Ethernet
5 connector, check the system-error log or IMM2 system event log (see “Event logs” on page 331),
make sure:
a. Fan 3 is running in standby mode, if Emulex dual port 10GBase-T embedded adapter is installed.
b. The room temperature is not too high (see “Specifications” on page 1).
c. The air vents are not blocked.
d. The air baffle is installed securely.
2. Reseat the dual-port network adapter.
3. Turn off the server and disconnect it from the power source; then, wait 10 seconds before restarting the
server.
4. If the problem still remains, replace the dual-port network adapter.

Server hangs during the UEFI boot process
If the system hangs during the UEFI boot process with the message UEFI: DXE INIT on the display, make sure
that Option ROMs were not configured with a setting of Legacy. You can remotely view the current settings
for Option ROMs by running the following command using the Lenovo XClarity Essentials OneCLI:
onecli config show EnableDisableAdapterOptionROMSupport --bmc xcc_userid:xcc_password@xcc_ipaddress
To recover a system that hangs during the boot process with Legacy Option ROM settings, see the following
Tech Tip:

If legacy Option ROMs must be used, do not set slot Option ROMs to Legacy on the Devices and I/O Ports
menu. Instead, set slot Option ROMs to Auto (the default setting), and set the System Boot Mode to Legacy
Mode. Legacy option ROMs will be invoked shortly before the system boots.
