12
Implication Users should use the IPMI over LAN interface to connect to the BMC. This only
affects serial and terminal mode access to the BMC. This does not affect BIOS
console redirection via serial and operating system redirection via serial.
Status This erratum may be fixed in a future firmware revision and hardware revision.
Workaround None.
12. Serial over LAN and IPMI over LAN connections may terminate
unexpectedly under certain conditions
Problem During an active Serial over LAN connection or during an active IPMI over LAN
connection to the BMC, the connection may be lost intermittently during a DC
cycle or reset.
Implication The user’s connection may be lost causing the user to reconnect the session.
Status This erratum may be fixed in a future firmware revision.
Workaround None.
13. Intermittent beep code 1-5-2-1 when booting with dual processors
Problem During POST, the system may pause at POST code 0x13 (SMM Intialization).
If dual processors are installed, this may result in a 1-5-2-1 beep code and a
processor event in the System Event Log (SEL).
Implication The system may log erroneous errors in the SEL or via beep code. Under some
conditions, the system may halt at 0x13 and require an AC cycle.
Status This erratum is fixed in BMC release 47 and later releases.
Workaround If an error is encountered, AC cycle the system and the system should run
normally.
14. Power Supply population errors may not appear in SEL
Problem The BMC will not give any indication if a single power supply is improperly
installed in a redundant chassis.
Implication Some chassis require power supplies to be installed in specific slots if a single
power supply is installed.
Status This erratum was fixed with BMC 36 and FRUSDR 20.
Workaround None.
