to check the settings:
LANCP> show dev ewa0/char
Device Characteristics EWA0:
1500 Device buffer size
Normal Controller mode
External Internal loopback mode
00-00-F8-06-88-5A Hardware LAN address
Multicast address list
CSMA/CD Communication medium
FF-FF-FF-FF-FF-FF Current LAN address
128 Minimum receive buffers
256 Maximum receive buffers
Yes Full duplex enable
Yes Full duplex operational
TwistedPair Line media type
100 Line speed (mbps)
Disabled/No Failset Logical LAN state
0 Failover priority
Replace ewa0 with ewb0 for your config.
Also show dev/full should verify the card in use (again replace ewb0 for your config)
$ show dev ewa0/full
Device EWA0:, device type DE500, is online, network device, device is a template

How does tcpip show inter look like? Which address do you try to ping? The best choice is the next router to you.

How about TCP/IP settings, is the interface properly configured?
You can verify the settings with:
$ TCPIP ! or UCX on older VMS versions
TCPIP> SHOW INTERFACE/FULL
This shows you the settings and the counters for each interface (network card + loop device)

How about the speed ?
In >>> show ew* and/or show ei* depending an the type of cards.
Linespeed should be correct for the switch or hub which you are using.
Watch also about the duplex/full duplex setting. If you are using autonogotiating: Switch this off. Most of the switches won't work correctly. Fur sure: 3com, Cisco.
Set the ports if you can to 100 Mb/Full Duplex and most of the times this will do the trick.
Hubs are halfduplex.

At $show dev ewb0/full alllooks OK.
Not sure how too disable autonogotiating.
I'm on VMS Ver 6.2-1H3, can't seem to get TCPIP to work.
The card is set with
The activity light is constantly flashing, not sure why this is happening when nothing is going on?
Any other ideas?

If you are on VMS 6.2-1H3 use
Or perhaps you are using another third party TCP/IP stack?
At the UCX prompt type:
UCX> SHOW INTERFACE/FULL
This will display you the interface settings and also the counters on each card (Receive and send packets etc...)
Also as mentioned by Anton you must properly set the linespeed and the half - full/duplex settings on the switch. Disable autonegotiating.
And I remember that there is almost one ethernet card that you can 'overspeed' in >>>.
With overspeed I intend that you can set Fast Full duplex on a 10baseT card.
Now I cant remember which adapter was, the only thing I remember is that it was an AS 1000 alpha.

I too had a problem with DE500-BA on AS2100 in the past...
There are several variants of DE500. Depending on the combination of your OpenVMS version and the DE500 variation, it may be working or not. There are certain HP requirements about that. There are ECO kits that enable support of DE500 for specific versions of OpenVMS. Try to look up the necessary patch at http://www2.itrc.hp.com/service/patch/mainPage.do . Its name should start with "ALPLAN" or "ALPBOOT".
There was also quite a bit of answers about DE500 at OVMS Ask The Wizard. Try to do a search for "DE500" at http://h71000.www7.hp.com/wizard/ .

there is a discussion of the various DE500 variants in the FAQ at
Having said that, if you get it to work, the DE500 is really great for a 100Mbit card.
