Having 2 physical links between ethernet switches requires link aggregation,
port bonding, whatever the switch vendor calls it. All switches with such
capability fall into the "managed switch" product category.
If these are managed switches, read the documentation and find out if they
support link aggregation. If they are not managed switches, then make sure
there is only one uplink cable between the switches.
If you would provide us with the brand and model of the switches we could
probably tell you pretty quickly if they support link aggregation or not.
