Good morning all!
I currently have 2x PC6248's that are stacked with YY741 stacking module and 2x Dell F4XF-F4XF 1 meter cables between them and it's all working fine. # show stack-port indicates that xg1 and xg2 are in use on both switches while xg3 and xg4 are both down. This is what I'd expect.
I need to add two more switches but they are going to be at quite a distance away. The first would be approximately 15 meters away and the second would be somewhere between 75 and 100 meters away. Can I use F4XF-F4XF cables that long to 'stack' the switches and if so, where can I find cables of that length? If I can do this, can I get away with just 1 cable to the remote switches? (Yes, I know it would only be a 12GB inter-connect).
If the above answer is no, then can I put 2x gbic's in the xg3/xg4 ports on both the existing switches and and 4x gbic's in xg1-xg4 on the new switches and connect cross-connect the two new switches over LC-LC fiber going that length? (Yes, I know xg1/xg2 are not usable in the existing stack). If I can do it this way, what gbic's would I want to get? Can I use any LC-LC gbic or are there specific gbic's I should use? And, how would I configure all the switches? I do have multiple vlan's in the existing stack. My config is attached below (if you see any errors, feel free to say so lol), it's pretty basic. All the ports in chassis #1 are in use with a few on chassis #2. Currently, with only the 2 switches in the stack, everything is working perfectly.
