Can't see Catalyst 2960 48TT

[Hristo Todorov]

I had to connect a new Catalyst 2960 48TT switch to my Network. Which is connected straight to port two in Catalyst 3750G 48+4. I have three other already connected: 2 x Catalyst 2960 48TT and 1 Catalyst 2960 48TC.

The problem is I can not see the newly connected switch in Cisco Network Assistant.  I see the other two switches but not the new one.

I have couple of computers connected to the new switch which are working fine.

I changed the main cables which go from 3750G to the other switches.

The network is working fine, the connected compuetrs have internet...

Can someone please help...?

Does the switch have a managemen address?
