- SUBJECT : NE2000 & NP600 Communication Problem
- DATE : 5/2/90
- FYI # : 050290sb
- OS VERSION : SFT v2.15 (Server 1)
- REVISION : C
- OS VERSION : 386 v3.0 (Server 2)
- REVISION : B
-
- SHELL VERSION :
-
- GENERAL INFORMATION : The 286 server is running two NP600s one
- of which is the backbone to the 386 which
- is running three NE2000s. The users on
- the 286 use some of the information on the
- 386 server. The users on the 386 almost
- never need access to the 286 server.
-
- PROBLEM : When the backbone is attached to an
- NE2000 set at IO address 340h the NE2000
- will no longer receive from the NP600.
-
- SOLUTION : We switched the backbone cable to a card
- set at IO address 300h and the cards are
- working fine. The workstations have Western
- Digital 8003Es in them.
-
- COMMENTS (Optional) : It seems that the IO address affects the
- resistance of the BNC connection of
- NE2000. We set several NE2000s up with
- different IO addresses and tested for
- resistance after IPX was run on separate
- cable segements. The resistance did vary
- on each card after the IO was changed, but
- the variance was not uniform or
- predictable. I think that the large
- change in resistance that accounts for the
- problem with the NP600 is confined to a
- small number of cards.
