Changing or creating any user account settings remotely requires that a tool or a user log
in using a username and password of an account that has ADMIN privileges, before any
parameter value changes will be accepted. New account creation and deletion remotely is
only allowed for accounts with the ADMIN privilege.
One of the features of the Intel
®
RMM’s local and remote utilities is the ability to invoke a
self test of the Intel
®
RMM. The following interfaces are tested by the Intel
®
RMM Self
Test:
FML to the BMC
IPMB
USB
DVO
LAN
The Fast Management Link (FML) is a high speed (8 Mb/s) point-to-point interface
between the Intel
®
RMM and the BMC within the Intel
®
631xESB / 632xESB I/O
Controller Hub. For the FML to the BMC self test, the Intel
®
RMM FML interface sends
a “Status Request” to the BMC and waits up to one second for a reply. This test exercises
the data and control signals of the FML interface. If a valid response is returned from the
BMC in the allowed time, the test passes. If a valid response is not returned in time, then
the test fails.
Testing the DVO interface involves a test to check if the internal KVM firmware is
running. If the KVM firmware is running, then the self test will generate a signal that will
be accepted by the KVM firmware. As a result of accepting the signal, the KVM firmware
will create a file in the /tmp directory of the firmware’s file system. The file will contain a
“detected video” if the signal was detected. Otherwise, the test fails.
Testing the IPMB with the Intel
®
RMM’s self test involves sending the BMC an IPMI
command via the IPMB. If a response is received from the BMC, then the IPMB is
working. Receiving no response from the BMC indicates that IPMB test failed.
The USB interface of the Intel
®
RMM is a “target only” to the USB host controller
embedded in the Intel
®
631xESB / 632xESB I/O Controller Hub. There is no way for the
Intel
®
RMM to initiate USB traffic. Therefore, testing the USB interface consists of
receiving a read request from the USB host controller over the USB and successfully
responding to it. The Intel
®
RMM self test can keep track of this occurrence to indicate a
