SG500X-24P-K9-G5 Stacking

Good morning,

what is maximum length between the switches for stacking ?

In this case there are 4 SG500X-24P-K9-G5 in two different rooms. Cablelength ist about 450m.

Is it possible to stack all 4 switches with SFP-10G-LR Gbics.

 

Thanks

 

Boris

SG500 has this feature to be

SG500 has this feature to be able to stack using ethernet or Fiber (if you have SFP).
Note that you still need to follow recommended lengths of cable

For Copper: maximum of 100m     -I do recommend to keep at less than 90m
For Fiber: It's fiber, almost indefinite.

Also, if you are using copper, I do recommend using CAT5E or better yet CAT6/CAT6A and make sure all the pairs are complete since 1Gbps requires all of the UTP cables present.

PS: In our enterprise, we never have stacking w/c involves the switch located on another room. Most of the switches are on one IDF. For example, enterprise level switches e.g., 3850 switches. They never are in another room that is almost, as you said 450meters away from each other. What's the difference you may ask? Well, for your SG500(assume you are using copper), the stack speed is 1Gbps/stack hence total of 2Gbps stack speed. The 3850 can reach 480Gbps stack speed.

If you want Layer 2 redundancy on w/c you desire that the devices are in separate rooms, above 100m, you need L2 redundancy supported device w/c can only be found on Nexus switches through their VPC feature. Of course, this is on the enterprise level, but your goal on having them separated 450m away is achievable through this. Besides that, because of portchannel feature, you can group the peer-link ports. If you have 10Gbps of ports, hence you get a total of 80Gbps of speed on the peer link
