Aironet 1140 series units won't connect to a gigabit switch

[andye8888]

I just installed 2 new units and neither will connect to a new HP gigabit switch - no link light, other devices can connect to the switch OK.  Their gigabit ethernet settings are set to auto for duplex and speed.  I also tried forcing one of them to full duplex and 1000 Mbps which didn't work either.  They're both powered by POE injectors.  If I connect them to a 10/100 switch they work fine.

Am I missing something?

If I have a dollar for situations like these, I'd be a zillionaire!

You have a cable problem.  If you can run TDR tests on the cable, you'll see that the 4th pair is not terminated.

In debt, Scott.  Only in debt.  Hence I work.

Leo,

Thanks for the reply, sorry I'm late getting back to this, I was lucky enough to have a long weekend off.

I'm no cabling expert, that's why I hired somebody else to do it.  But I have a question: should standard cat 5 cable work?

If so, I disconnect the WAP from the cabling that was installed and hooked it up with cat 5 patch cables that I confirmed to be work OK by using them to connect the gigabit switch to a laptop.  When I used the same patch cables on the WAP I still got a failure to connect to the same switch.  So unless it's not standard cat 5 that I should be using it doesn't appear that cabling is my problem.

[Leo Laohoo]

A number of Cisco Catalyst switches support a copper line testing called TDR.

Standard Cat5 will work but you really want something better like Cat5e or Cat6 .

PS:  No cabling expert either.

Thanks for your help anyway.
