Oh, yeah.
Although there are still three model ranges (9402, 9404, and 9406)
from smallest to largest capacity, the second half of the model number
is actually the one that the machines are know by. Examples would be
9402-E06, 9404-E25, 9402-400, 9402-F02, 9402-40S, 9406-D80, 9404-F10,
9406-320, 9406-640. These would be referred to as model E6's, E25's,
640's, etc. Basically, anything starting with a letter other than an
S, is from the original CISC family.
If yours actually says "9406-320", then you have a model 320. You said
the label was marked with "320W". Well, the power supplies for the
earlier systems were rated at 320Watts, so that might be what you are
seeing. The tag for the model number should also be where the serial
number is on the outside of the case. If it has a "9402-xxx", then
that is the model number. If it is actually what you typed, "4902",
then this is an identification tag that is not from IBM. The IBM
serial number tag is clearly marked IBM and the serial number is
listed as "S/N: xx-xxxxx".
There is actually a third part to identifying the machine you have.
That is the processor feature code. For example, a model 9406-320 with
the processor feature code #2050 has one processor. The 9406-320
FC#2051 has two and the 9406-320 FC#2052 has four. The performance
ratings are obviously very different.
Check out http://publib.boulder.ibm.com/pubs/html/as400/onlinelib.htm
for documentation on the older systems. Unfortunately, they only go
back to V4R1Mx online, and only cover back as far as the model 4xx
hardware. I, however, believe I still have V2R3M0 documentation stored
in the basement if you are interested in pursuing it.
Check for document GA19-5486-18 online. The title is "AS/400 System
Handbook". It is an ITSO (International Technical Support
Organization) publication known as a "RedBook", as opposed to an
actual manual. It is actully for OS/400 V4R3Mx and V4R4Mx, but the
appendix give some basic information on all of the earlier models.
You need the right model number and the right OS version to determine
the meanings of the SRC codes as they changed from model to model, and
some times from OS version to version on the same model.
The original cabinets were that old PC "putty" colour. Then they went
to an all black case when they changed the definition of AS/400 from
"Application System/400" to "Advanced System/400". Later, they split
the model line in to two and the "AS/400e" was born. The "Server"
models had a red stripe. The "Interactve" models had a blue stripe.
The "Dominoe" models had a yellow stripe which earned it the nickname
"bumble-bee". The latest variation is a copper stripe, representing
the new copper processor technology.
For information about the current systems, see
http://www-912.ibm.com/supporthome.nsf/document/18425302 for
documentation.
The AS/400 was renamed the "iSeries" as part of the "eServer" line.
The AS/400 became the "eServer iSeries", the RS/6000 became the
"eServer pSeries", the S/390 mainframe became the "eServer zSeries",
and the Netfinity servers (Windows xx machines) became the "eServer
xSeries".
By the way; you can install xSeries server motherboards as expansion
cards to the iSeries. At that point, you could be running four
seperate OS's under the same cover. OS/400 as the managing, native
partition; AIX as a secondary partition, running the same CPUs in a
different mode; Linux as a secondary partition running the same CPUs
in a different mode; WinNT, Win2k, or whatever you want running the
Intel processor based xSeries "server-on-a-card" as an expansion card.
