Here is quick summary on what you have.
1. Some bootable O350 (Origin/Onyx - not really important as it is modular system and all parts are inter-changeable).
These are ones with the IO9 card in bottom slot, with combination of Ethernet / SCSI port.
The ones with Graphics in them will report as Chimera Blade the ones without as Chimera Server.
2. Some expansion chassis, some of which look to have CPU modules in then.
These are ones without the IO9 board.
Some may not have CPU modules .. again you will find that depending what’s in side the module will determine what you can do with it, but all modules have same basic parts.
3. Some AC Numalink Router Modules
lucky you these are hard to source, but can be hard to get running if serial numbers are not aligned
But seeing you have 2 your system units will likely need to be assembled into 2 independent systems.
The very fat cables are the Numalink cables. These are used to connect to router.
Use the bottom 4 ports on Router first as these have USB embedded, while top 4 do not.
Also the Numalink ports on your bootable chassis are on rightside, looking at back of machine.
4. Finally you have L2 controller
The small metal box with Ethernet, USB and RS-232 ports.
Here is plan of attack:
1. You need to see what serial numbers the various chassis have. This can be done without booting machines. Each machine has serial console port which provides interface to embedded L1 controller
2. Simply plug in each in turn with serial cable plugged in (38400/8/N) and do “serial”. Note serial and also do “config” to get rack/slot identifiers.
3. To be safe you should get your serials before plugging things together with Numalink or usb to L2, as otherwise serials might get flipped on you.
4. Now get your L2 running. Again you can plug into serial port to see boot diagnostics. Through the serial port you should be able to get serial of L2 and see/set IP address. Try to get network connectivity to L2 and telnet to it. This is useful as L2 provides way to access all modules without having to go to serial port all the time.
5. Your setup could be configured as either all the same serial managed via single l2 or different serials, which would require different L2s, your serial discovery will answer that question.
6. Now plug each of the Numalink routers (do one at a time) into the L2 via USB cable and see if these have aligned serials. If they do, then you can start to link all the classics to appropriate router via Numalink cables.
7. Once all linked up do “serial all” on L2 (using telnet now) and be prepared to see lots of info.... as per prior comment if you use lower Numalink ports then you will only need USB cabling from router to L2.
8. You are now ready to report on hinv forum
and can even try to boot by doing “power up” on L2. Then control-d to see boot diagnostics across all the machines.
