Installing a new Gigabyte switch

[Red and White]

just got a new switch to go into a very crowded cabinet.

thing is ive never put one in before. is there a special way it needs to be connected, or can it be connected to any port on one of the other swtiches??

theres so many wires in the cabinet i cant see how anything is connected it really is ridiulous. ive managed to connect anway and all the lights are flashing green, and everything appears to be working so im happy enough
