Mfr_ID (0x99): Manufacturer in ASCII – 5 characters
maximum,
General Electric – Critical Power represented as: GE-CP
Mfr_MODEL (0x9A): Manufacturer model-number in ASCII –
16 characters, for this unit: CAR2012TEBXXZ01A
Mfr_serial (0x9E): Product serial number includes the
manufacturing date, manufacturing location in up to 15
characters. For example:
13KZ51018193xxx, is decoded as;
13 – year of manufacture, 2013
KZ – manufacturing location, in this case Matamoros
51 – week of manufacture
018193xxx – serial #, mfr choice
note: if the additional xxx space is not utilized then F’s
are filled in, (i.e. 018193FFF), ensuring that the actual serial
number is clearly identified.
Manufacturer-Specific PMBus^TM Commands
Many of the manufacturer-specific commands read back
more than two bytes. If more than two bytes of data are
returned, the standard SMBus^TM Block read is utilized. In this
process, the Master issues a Write command followed by the
data transfer from the power supply. The first byte of the
Block Read data field sends back in hex format the number of
data bytes, exclusive of the PEC number, that follows. Analog
data is always transmitted LSB followed by MSB. A No-ack
following the PEC byte signifies that the transmission is
complete and is being terminated by the ‘host’.
Mfr_Specific Status and alarm registers: The content and
partitioning of these registers is significantly different than
the standard register set in the PMBus™ specification. More
information is provided by these registers and they are either
accessed rapidly, at once, using the ‘multi parameter’ read
back scheme of this document, or in batches of two STATUS
and two ALARM registers.
Read_std_parameters (0xD0) : This ‘manufacturer specific’
command is the basic read back returning STATUS and
ALARM register data, output voltage, output current, and
internal temperature data in a single read.

Isolation test failed: The ‘system controller’ has to determine
that sufficient capacity exists in the system to take a power
supply ‘off line’ in order to test its isolation capability. Since
the power supply cannot determine whether sufficient
redundancy is available, the results of this test are provided,
but the ‘internal fault’ flag is not set.
