Power loss droping TR Segment Question

Power loss droping TR Segment Question

Power loss droping TR Segment Question

Here is the siutation:  I  Have a mixed environment of TR and Fast/Giga Ethernet.  When any of our MSAU's losses power for a period longer than 5 minutes it is EXTREMELY dificult to get it back on line.  I am able to connetct to the switch from the Netowrk Uplink that usually backbones the MSAU to the switch via a Laptop but as soon as I try to connect thru the MSAU ..........nothing happens.  Literally hours go by before the situation is cleared up.  By the way, Olicom Crossfire 8600 TR Switch and Andrews 9328 Extended distance MSAU's.  I have tried disabling and re-enbling the Switch port that hte MSAU connects to and still nothing.  Hopefully some people still look at this particular forum and can help. We are in So Cal and feeling the effects of the "brownouts" on a regular basis!!  


RE: Power loss droping TR Segment Question

Firstly mate UPS your kit to save you having to mess about next time it happens.  Secondly check all your kit is set up to use either Fix 16 or Fix 4 what ever it is you run.  If you have an old mau then port reset and lastly run something like sniffer to find out exactly what is happening on the ring at the time of the problem. It may be that you will have to get every user to reboot before the problem rectifies.  In all cases move a way from non managed Token ring kit and at lease to a CAU and Lam scenario from madge or ibm then you can diagnose t/r better.

RE: Power loss droping TR Segment Question

Thanks for the response.  We had a transformer of ours hit by lightning the other day and looks like it took out the MAU.  I installed a TR Switch in place and things are finally getting back to normal.  I thank you for your advice, I will be getting rid of my last T/R segment in about 2 months putting in it's place switched 100 MB to the desktop with a giga back bone infaastructure.  Hopefully this will all be behind me in a few months.

Thank You again,
