Oh, and I would advise to manage the switch. This way you can access it remotely and make any changes that come up later, instead of having to be locally at the switch.
</div>


<div>
Just to add on what Syed said.<br />
<br />
Yes, use the correct SFP modules. Make sure that the SFP module is MM and not SM. Also, yes, if you need to manage the switch create a VLAN interface and assign an ip address on the subnet that the 3750's vlan reside on.<br />
<br />
So:<br />
interface vlan x <br />
ip address x.x.x.x 255.255.255.0 (Assuming)<br />
no shut

Hello and thank you for the quick reply. &nbsp;We do have VLAN in our envoirnment. &nbsp;Oh yeah it LC/LC connection. <br />
<br />
Soulja...... you are assuming that I have done copper before well I have not.....:[....<br />
<br />
Syed.......thank you for links I am doing my research on this. &nbsp;<br />
<br />
Like I said I have never done this before and I am excited that I get to do it now. &nbsp;It has been along time since I programed a switch so I am alot rusty........
</div>


<div>
&quot;<i>Soulja...... you are assuming that I have done copper before well I have not.....:[....</i>&quot;<br />
<br />
What do you currently have plugged into the 3750 switch. You have copper twisted pair going to your clients, servers, etc. Correct? That is what I meant. Fiber is really no different when it comes to configuring the ports. <br />

</div>


<div>
Another tip when you connect the fiber modules, if the link light does not come ON. &nbsp;Switch your fiber leads around. &nbsp;XMIT to RCV and vice versa. &nbsp;It gets me all the time.

@shadowmantx<br />
<br />
If he is using LC/LC that should be and issue since you can only plug them in one direction. Now LC/SC or SC/SC, then you run into those TX/RX issues. 
</div>


<div>
I meant : If he is using LC/LC that <b>shouldn't</b> be and issue since you can only plug them in one direction.
</div>


<div>
Syed............the module we are using is Cisco GE SFP LC CON SX so I am a little confused.....is this the right module
</div>


<div>
That module should work for you. 
</div>


<div>
if you are using Multi Mode fibre than this should be fine, make sure you have this part # <br />
GLC-SX-MM (GE SFP, LC CONNECTOR SX TRANSCEIVER).<br />
<br />
i would also sugegst you check with Local Cisco partner and verify. <br />

</div>


<div>
You can get LC/LC polarity mixed up. &nbsp;It not only depends on the patch cables, but also the structured cabling between patch panels. &nbsp;I've worked at hundreds of sites and this is a common problem with all common connectors (ST, SC and LC).<br />
<br />
Anyhow, the modules will be fine as long as they are 1000Base-SX. &nbsp;The module to use is GLC-SX-MM in both switches in this instance. &nbsp;If the link doesn't come up first time, swap the plugs over at one end of the link. &nbsp;It might be a bit fiddly to unclip the retainer on the cable but it will come undone with a little force.
</div>


<div>
Ok got it GLC-SX-MM. &nbsp;Now ya make it seems like all I have to do is plug the fiber both switches and put switch B on the same vlan as switch A and everything should be okay. &nbsp;I am sure once I get more into this I will have more questions. 
</div>


<div>
you are right, but i would suggest you close this case and if you have more questions in future please open new case.<br />
<br />
you may have question relating Vlan and Etehrchannel and for that you can refer to my first post.<br />
<br />
Thank you

Hello<br />
We have a switch stack of 4 Cisco 3750G switches and I will be running about 200 ft of fiber &nbsp;SFP MM Duplex from one of those switches(switch A) to a brand new Cisco 2960 (switch B). &nbsp; I have never done anything like this before so I am very excited and a little nervous. &nbsp;<br />
<br />
Switch B is a managable switch but I don't want to manage it, I need it to be a dummy switch to pass through data or should I manage it will that give me faster access<br />
<br />
Switch A is an internal switch that is not hooked up to the internet.<br />
<br />
Can someone help me with this or point me to a place I can find more information about doing this type of connection.....

connecting cisco 3750g to 2960s via fiber

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
