876.0. "Why DECNIS F621 use S-type key for DAS?" by TKTVFS::IDO (Naoki Ido, CSC/TOKYO, EWB, DTN 680-2456) Fri Feb 26 1993 02:58

Why NEWPORT is using S-type keies in  A and B receptacles on DAS version?
Is there any reason? Here in Japan, most of FDDI customers are using the mold 
type MIC. Those are not programable like Digital's BN24 type cable.

876.1where's the F621 docu Online??ZUR01::HOTZGregor; MCS, NaC Support, SchweizFri Feb 26 1993 05:1919
Hi Naoki,
I don't know why it is the way it is.  I let others comment on that.

But the SERVICE_INSTRUCTIONS docu page 2-7 (see below) tell
you how to remove or change the key. It also says "optional PHY A, PHY B,
and PHY M keys ship separatly". I wonder, did they ship with the module?
Why is there an M key?? I'd say its not used.

well, just tried it. I get 

-RMS-E-PRV, insufficient privilege or file protection violation

it worked last week. I've deleted it after I copied and printed it.

EK-A0600-PR is the docu number.

Interesting.

Who makes those connectors that have fixed keys?  I have never heard of any
before -- all the ones I can remember have selectable keys.

Note that you can always use S connectors: those fit into any receptacle.

876.3The prastic key could remove but ..EWBV06::IDOMon Mar 01 1993 23:049
Greg and Paul,

Thanks for your info. I have checked several DECNISs with DNSAF. All of
those DNSAFs have always S-Type receptacles regardless SA or DAS.
I could remove the prastic key from the receptacle to make the port fits
all of types, but It is still problem if newport uses S key for DAS ports 
from now on.

876.4DNSAF MIC keying will be fixed !REOTN3::JUNO::STRATFORDTue Mar 02 1993 17:0029
Naoki,

	clearly this is wrong.

	DECNIS DNSAF multimode options using MIC connectors should be correctly
	keyed for each PHY port.

	This was an omission in our manufacturing assembly process.

        The MODPMD daughter cards are built in Augusta and fitted with the "S"
        key. They are then shipped along with all the other key types to our
        manufacturing plant in Galway where the rest of the DNSAF module is
        built and assembled.

	The MODPMD cards are assembled but unfortunately the MIC keying is not
	changed for the DAS variants.

	Whoops.

	The assembly process is being modified and all future DNSAF will be
	correctly keyed.

	The comment regarding the MODPMD spares is correct for the same reason
	as above. The MODPMD comes with all the keys you might need. The
	replacement instructions show you how to remove and install the correct
	keying when replacing a multimode MODPMD card in DNSAF.
