FIber Connection Between Dell 5324 and Cisco 2900
I'm trying to connect two swicths together via fiber. I'm trying to do this with a Dell 5324 and a Cisco 2900 XL. I pluged in a fiber optic cord into both and got nothing (If only it was that easy :) ) I have a optical transiever plugged into the dell powerconnect 5334 combo port, when it put the transiever in the dell it does dectect it but it does not detect the connection to the cisco switch. When I plug the fiber into the cisco switch the terminal doesn't show anything. I'm not sure what I have to do to get these to work together. Do i need to setup a upload port on both of them? I've changed fiber cords thinking it was the cord but that didn't work, and when the cord it plugged into the dell I can see the red laser at the other end. I'm really lost as to why I can't these 2 switches to connect via fiber. Please help, any sugesstions???
Thanks

Thanks yasirifan,
I looked all over dell's stupid web administration page and I can't find anything on how to make a uplink or on the dell or how to configure it to work in trunk mode, the only thing I can find is the MDI/MDIX settings listed, but that is all they have as far as port configuration. Does anyone have any idea about how to go about configure my dell switch??

OK,
Go to the VLAN membership page first.
Create the VLANs you need active on this switch
Then in the select VLAN field, you can select all of the vlans that you have just created. Make sure that for the trunk port, VLAN1 is untagged, and the rest of the vlans is tagged (you wull recognize a tagged VLAN by a T, and an untagged VLAN by a U)
So if you have VLAN 1, 2 and 3 you need to have VLAN1=U, VLAN2=T, VLAN3=T
Once this is done, your trunk port has been setup.
normal access ports just have one untagged VLAN on the port (the U should be visible only for the VLAN that port is active for.)
To activate the ports in that VLAN, now go to the VLAN port settings page, and assign each port the correct PVID (VLAN that the port is in), for the trunk port, assign PVID 1)
that should do the trick !
If you need more info (with screenshots) just let me know

I'm trying that right now on my dell switch
- it would be easier with screenshots but if its to much of a hassle its alright.

Attached some screenshots. In my case, port 1 is the trunk port to a cisco switch. The Cisco switch has a config as described in the first comment of this question. I am having 3 VLANs (1, 4 and 6)
VL1.jpg = setting for VLAN1 in Vlan membership page
VL4.jpg = setting for VLAN4 in Vlan membership page
VL6.jpg = setting for VLAN6 in Vlan membership page
portmem.jpg : Settings on the port VLAN memebership page.
That should do the trick (well let's hope so :-)

ck459, did u connect your dell switch to your cisco switch via fiber? Just wondering, still fooling around with it, so far no link, the screen shots where a big help thanks.
No, my connection was copper. You probably already tried swapping transmit and receive ?
what kind of fiber GBICs do you use? SX?

I have a LC connector on my dell and a SC connector on my cisco and i beileve im using FX. But im still having a hard time trying to get the to connect.
this is what what GBIC and SFP you should have :
GBIC (on the Cisco 2900) : WS-G5484
SFP (on DELL end) : GLC-SX-MM
On the Cisco end, you may need to swap transmit and receive to make it work
What type of fiber lead are you using ?

SFP (on DELL end) : GLC-SX-MM

On my cisco swich is a 4 port WS-X2924-XL-L fiber card and i don't know what type is in the dell, its just a LC fiber optic transceiver plugged into my dell' combo port.
- I switched the two cords around on the cisco end if that is what you mean my switching send and recieve. But still there is no link.
- and im just using a standard LC to SC fiber patch cord which says it is 62.5/125

Fiber lead is OK, but the 4 port module is a 100baseFX module, and I'm afraid that's not compatible with the 1000BaseFX SFP transceiver in the DELL (you might want to check if you can change the speed on that port, but I don't think you can). I'm checking if there are other options to get this to work.

Thanks a lot ck459 if you can make this work, you would be my hero!!

I got the port speed set to 100M by putting auto negotiation to disable but still have nothing.
I have to run out for about an hour so If i don't respond back that is why, but when i get back I plan on working on this when i get back, I have to get this to work even if it takes me all night.

Would connecting them with copper be an option ? Even if it is a temp solution...

Oh thanks ck459, i didn't even realize that thanks a lot!!! My dell transceiver is a X3369 DELL GIGABIT SX LC SFP OEM. Thanks sooo much ck459. You saved me a lot of time, i would have been up all night trying to get this stupid thing to work, i really owe you one :)
thanks for all your help through this, you've been a life saver.
I have one last thing to pick your brain with this
- I already have pre wired fiber in our building and its a long run and its all set and I really really don't want to have to re run another fiber line. Because its a LC to SC fiber cable im not sure what to do?? I mean i could if i buy another cisco switch how am i to connect it to the other because I don't think i can get a LC 100FX card for cisco switches do they???
What would you do. Once again thanks for all your time

Hi Sgfjacobs,
Well, There's 2 things you can do.
First thing is to by another cisco switch (on ebay for example, they're not that expensive anymore) that does have 1000Base-SX. The type you would need to look at is 3524XL, or 2924XL-EN (not the M series), or 2950 (2960 will also do), or 3550 (although the latter one will be more expensive) These switched can be equipped with 1000Base-SX GBICs (WS-G5484). Be carefull when chosing a switch, on which fiber tranceiver it needs ( any switch that supports WS-G5484 or SFP-SX-MM will do)
And then you can connect you're Dell with Gig speed to the new Cisco switch.
Cisco does have SFP tranceivers with 100BaseFX, but I you would need a 3560,3750 or 2970 switch, and they are quite expensive. So if money is not an issue you can go this way, and purchase a 3560,3750 or 2970 together with a GLC-GE-100FX (see more info on below Cisco page)

Example of a Cisco 3524 that would work in your case :
http://cgi.benl.ebay.be/Ci
You can use the same fiber lead (the Cisco side thoday has SC, and the above switch takes SC GBICS)
Only extra thing you would need is a WS-G5484:

These are just examples, it just gives you an idea of the prices of this stuff if you this second hand today.

Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
