if it was a layer 3 switch where it does routing internally, it may need special configuration, just for it to work.
But if its a layer 2 switch, should make little difference to the reliability, or efficiency of the switch.
Since a layer 2 switch only repeats data to the destination port, it effectively blocks the traffic to any other port anyway.
Only if your switch is subject to ARP poisoning could this be a problem, but most now-a-days are not.
Ensure if there are loops in your switches, Spanning Tree Protocol should be enabled..
