How do I connect two switches
I have two XS508M 10gb switches. Can someone please tell me the best way to connect either together or direct to router.
Do/can I connect the two switches together or should I run two independent cables to the router? Which would be the best.
Since switching to fibre the router (BT) only has 4 ports and really need 3 for other things. Tried connecting both switches and some kit will not work. (unless I connect to other switch) Do I need a crossover cable? Or connect each switch to router direct? Cat 6 cable with short (3mtr) run.
Thanks

This BT router (unknown to most people outside of the BT EU isolated world) does it have multiple 10 GbE capable ports?

Anything works - the question is much more: Should these ports be plain GigabitEthernet or some 2.5Gb only or max 5 Gb MultiGig, looping through the router will add a bottleneck if not going through a 10 GbE switch

Technically the XS505M and XS508M can accommodate any Fast Ethernet (100Mb/s), Gigabit Ethernet 1, MultiGig Ethernet (2.5 and 5 Gb/s) Ethernet, as well as 10 Gigabit devices, automatically, on fully correct wired connections.
10Mb/s Ethernet can't sync.

See above, already explained ref. bandwidth.

Nothing wrong with straight or fully and correctly wired crossover cables - most devices are supporting AutoX, straight cables are preferred.

More details please - what "some kits", what "other switch", and connected how please? Crystal ball is on a holiday in Transylvania.
Hi thanks for reply.
When l mentioned other kit l mean Hive control for central heating etc and another hub for home lighting control (Phillips Hue). When l added the second switch which was connected in series if you like then with another port connected to the router the two hubs would not work/connect. However when l connected the hubs to the other identical switch all worked ok. That seemed strange to me.
I will try two lines from router to each switch as soon as l make up a new cable.Regard to speeds no idea what the router gives but as l said both switches 10gb also the Nas drives on my network. The connected pc l just finished building is only 2.5gb motherboard as no spare slots for a 10gb card as used in my old scrapped pc. So a mixture of speeds.
But my main question is should l connect each switch individually to the router or just loop them together with one line to router?
Hope your crystal ball has a good holiday. Lol
Thanks again

Installing a new line does make sense only if the router does have two or more 10 GbE ports ... unless you are on a very new BT Business platform (e.g. using the Meraki MX75) very unlikely.
