Kontron AM4901 IPMI - Manual (Page 92)

IPMI Firmware User Guide AM5901/AM4901
Page 92 ID: 1035-8760, Rev. 3.0
11.5 R31
New:
1. Do not install a firmware of version R30 if the MCH runs in a rack of type OM6060 or
OM6040D. This could cause continuous resets.
2. Before the installation of a firmware of version >= R31 in a rack of type OM6060 or
OM6040D the Ethernet management port must be disabled by setting switch 2/1
(AM5901) alternatively 3/1 (AM4901) to position "ON". If the switch is set to "OFF" after
the installation and the MCH resets continuously then please set the appropriate switch
to position "ON" again to disable Ethernet at management port. The cause of the mal-
function is that the MCH's hardware configuration has to be modified. Please contact
Kontron for further assistance about the required modification (solder jumper).
3. In standard non-Kontron racks now a maximum of two standard cooling units are man-
aged. These units are working in parallel i.e. both have the same fan level at a time. If
only one unit is installed or working no error will be reported. Only if there is no working
unit at all is the error is detected (CLI command showerror), and the health LED lights up
red.
Restrictions:
1. The following types of FRU data records are not yet processed:
• MicroTCA FRU Information Partition Record
• MicroTCA Carrier Manager IP Link Record
• MicroTCA Carrier Information Record
• MicroTCA Shelf Manager IP Link Record
• MicroTCA Shelf Information Record
• MicroTCA FAN Geography Record
Please note that the contained information normally is not needed for the operation of
this MCH.
2. Only one Power Unit is supported
3. The input of a password at the CLI allows only 12 seconds waiting time per character. A
violation of this limit will cause a Watchdog reset of the MCH which will cause a reset of
the whole rack.
