So I've been troubleshooting random rapid/restore faults on a DLR ring with around 30 nodes. Checked cabling and connections, even got M12 D-code to RJ45 adapters to check those cables. Repaired a few cables that seemed suspect. Currently on the network there are EN2TR's, ETAPS, AENTR's, IFM AL1123's, and SMC EX260's. Changed out the EN2TR (ring supervisor) in the main PLC rack to a revision 10.007, thinking maybe port 2 was just acting strange. Then was not able to connect the ring without losing the last 6 SMCEX260 modules, which is right past an EN2TR in another rack. The DLR faceplate and ring supervisor show the ring is fine with no issues. This is while an EN2TR in another rack is going in/out of communications. If I leave the ring broken, everything works fine. If I connect the ring and set any of the ETaps as ring supervisor it works fine. Have not had any ring faults in the past 48 hours with the ETap as ring supervisor.
I would believe it is the revision of the EN2TR's causing the issues, but how would I check that? Also, why would the ETaps work fine with the DLR and not the EN2TR's?
The network is the following:
EN2TR in main PLC rack
ETAP - for PC connection
ETAP1F - fiber (negotiation forced to 100mbps)
ETAP1F - fiber (negotiation forced to 100mbps)
SMC EX260's (x4)
1734-AENTR
EN2TR
SMC EX260's (x3)
ETAP1F - fiber (negotiation forced to 100mbps)
ETAP1F - fiber (negotiation forced to 100mbps)
EN2TR
SMC-EX260's (x1)
1783-AENTR
SMC-EX260's (x4)
*EN2TR - This one seems to cycle the connection going on/off
*SMC-EX260's (x2)
IFM AL1123's (x3)
*SMC-EX260's (x2) - last port going back to main rack EN2TR
* These are the devices that lose connection when the EN2TR in the main rack is set as ring supervisor. The SMC-EX260's stay off (think that's just because they are slow to regain connection), the IFM AL1123's don't seem to lose connection or at least I don't get a yellow triangle on them.
