What boards have red lights?
If it is the VCU, then the HDD could be gone...

@WAITING FOR VCU READY
LOADING VCU WITH FILE H:VCU.IM

-End-
It just hangs there.  

The lights are as follows:
300-6039-004 CPU Green
300-6001-004 VCU Red & Green
300-6049-001 LAN Red & Green
300-6037-002 Fax Red & Green
300-6054-001 Line Red & Green

At a vendor's suggestion, we replaced the power supply to no avail.

Does it look like a problem with the VCU, or the VCU.IM file,  or do you think it is the Hard Drive?  The hard drive does seem to load some .IM files during boot process.

Thank you again, Doktor!

"do you think it is the Hard Drive" -> Yes, I am sorry to say.

Since 1993, where I began installing OCTEL 200/300's it has been the only HW component to fail, seen apart form the power supply.

By the way, the VCU is the HDD controller, and it is stable as h..., so best guess: HDD.

Thank you for your help, Herr Doktor.  

Well, believe it or not, this time it actually was the the VCU!  I got my hands on a replacement 300-6001-004 VCU card.  We popped it in and held our collective breath.  It booted up and all of the cards lit green.  The system is up and tested.

Thanks again.

I would also have: "held my breath".
But, still the system is stable as...
Check my reply to the back-up thread, also.

... It comes here.

Would be nice to have if the HDD fails.

It is possible to format standard floppies to OCTEL format.
But if you make back-up from the OCTEL to the floppy it will format to the correct "format" itself.

Names, Greetings, PDL's -> standard DOS format.

But if you want to make a system configuration back-up, you ned to send this command to the new floppy disk in the drive:
@CRE CFG
Also ALLWAYS remember to make at logged textfile (.txt) with all the data from

.list all (or .l all)

Thanks!  I will do that.  The thing is, we are updating everything (NEC 2400 and Octel 200)  to Cisco VOIP in September.  I hope the old Octel hangs on for another couple of months!

It will. Some of my system have been running since 1994  w/o reboot or faults.
