1260.0. "DE500-AA autosensing problem" by NETRIX::"[email protected]" (Dave Martino) Fri Feb 07 1997 16:04

I have a customer who has a DE500-AA 10/100 adapter installed on an 
AlphaStation 500/266 running Digital Unix v3.2G.  The AS firmware is 
6.0.  He is having a problem where the adapter apparently does not 
automatically adjust to the 10Mb/s speed of the network, and tries to 
run at 100Mb/s.  Any ideas on this autosensing problem?
Thanks,
- Dave Martino  DTN 521-4258

Response to .0 from Digital UNIX EtherWORKS driver developer:

>>The feature I believe that you're talking about is "Autonegotiation"...
>>
>>Autosensing is something entirely different.
>>
>>To enable autonegotiation, you need to set the 'mode' variable in the
>>console.  An example of this would be;
>>
>>	>>> set ewa0_mode auto-negotiate
>>
>>	>>> init
>>
>>
>>Then you can boot the system, and the auto negotiation feature will be
>>enabled.
>>
>>I have no idea what version of firmware you need to support setting the
>>"auto" mode...  But try it and see if it works.

1260.3OpenVMS and autoEVMS::JSTICKNEYJay Stickney, OpenVMS LAN Eng., 381-2020, ZK3-4/T12Fri Feb 14 1997 12:4816
    For OpenVMS:
    
    Device	Autosense	Autonegotiation
    ---------	---------	---------------
    DE500-XA	yes		no
    DE500-AA	yes		yes
    DE500-BA	yes		yes
    
    Some consoles have removed the EWA0_MODE selection of AUTO (for
    autosensing) but an autosense can still be done from LANCP once 
    VMS is up. The rest of the modes, including autonegotiation, can
    be set at the console or from LANCP.
    
    For OpenVMS versions that support these adapters see 1261.2.
    
    Jay.
