Hi,

There was lightning storm here the other day and the transformer infront of the office was hit. We lost power however there was a big bang and then nothing went to backup everything instantly shut off.
Anyway I majority of the equipment is fine.  The only wierd thing this is we have a 3com 3250 with to ports that show up red in the web interface.  But I think those 2 are blocking other from working fine.  Is there a way to reset inidvidual ports on these switches?  I have rebooted these several time.  but with no luck.

Thanks in advance.

Replace the switch.  When the switch hardware fails, it will not get better--only worse.  Also, it is not like plumbing, where you can isolate good from bad.

The switch is operating off of one electrical supply, one fabric, one set of firmware.  I think a lightning strike + failure is sufficient reason to replace it.

Check with your BBU warranty/guarantee and your electrical policy for reimbursement.

Also, I would have a licensed electrician check the grounding of your electrical mains and the bonding of your equipment.  Also, check the network and phone cables.  Was there an outside line connected to this switch (DSL/T1/cable router)?

Thanks.  I was hoping I would not have to buy another one.  Aww well.  No there were no outside lines connected.  And we did have a electrician come and and there were some issues with inconsistent power coming in.  So the City has to come it to check that out as well.

Thanks for you help.
