WHAT IS THE DIFFERENCE BETWEEN A 51 AND A 51C, AND ALSO THE SAME WITH AN 81 AND AN 81C ? THANKS

THE C STANDS FOR CORE, WHICH IS THE NEW ARCHITECTURE

Hi,

The biggest difference in the Non-c and C systems is the core.

The Non-C systems use an Omega CPU and the C systems use a Motarola CPU.

There are more differences but that's the biggest. If you want to know more I could look it up.

PS: The Core hardware isn't compatible with each other. 90% of the other hardware is...

I hate to bring up this old subject, but I'm wondering if there are specific differences that you could send to me through email (archibaldjcox@hotmail.com) regarding this matter. The reason I ask, is that if the difference between the C and non-C systems is the core, then which cores are specific to C-systems? According to some documentation the 81C can house the following: [red] NT6D66, NT9D19, NT5D10, NT5D03 and then the CP PII processors[/red], but if it's not in a Core/Net module ([green]NT5D21 or NT4N41[/green]), meaning that the system is using an [blue]NT6D60 Core Module[/blue], is it an 81C or is it an 81? The lines seem to blur a little and some of Nortel's documenation contradicts itself. Just hoping you had some insight to offer.

Thanks in Advance,
Arch

the C actually stands for the commerical processor ...meaning off the shelf available processor

beyond a software release(i dont knwo which one) ...the sytems need the c processor

The NT6D60 is an Option 81 you need the NT5D21 to run the 81C processor card. The following is part of an 81 to 81C upgade package.

Option 81C from Option 81 Card Cage Upgrade Package AC/DC
2 NT1R90BA Cardcage Upgrade Parts Kit
2 NT5D2104 Core/Network Cardcage (AC/DC)
2 NT5D30AA Dual Intergroup Switch
1 NT5D50AA SCSI Extension Cable
2 NT5D61AB IODU/C Pack
2 NT8D17FA Conference/TDS Card

 

[ArchibaldJCox]

So regardless of processor, if it doesn't have a Core/Net module then it's an 81? If it does have a Core/Net module (either NT5D21 or NT4N41) then it's an 81C?

Thanks,
Arch

Yes and the NT4n41 is for the CP PII processor the. At least that's what they tell me.

A give away for just an 81 (not C)is that the clock controller is usually located in the CPU shelf network side and has group 5 programed. In the network part of the shelf a 3PE (QPC441F) and the clock controler (OPC471H) are the only cards in the shelf. An 81 does not have an IODUC. It has a separate floppy disk/hard drive (CMDU) and an IOP.

the diff between a 61 and 81 is the number of cni. a 61 only has one group. net0 self 1 and 2. an 81 has 5+ groups. (it was just 5 before fugi).. ld 22 prt cequ, 125 23 ESF B8S FDL 00
140 24 ESF B8S FDL 00

that is a 81. in load 22 prt issp the ver number denotes the switch time and you'll see software release and patches.
