I don't think you should link the two switches with a cable.
A second Ethernet switch can connect servers to two separate physical networks without using VLANs, or connect servers to more than two separate networks using VLANs. A second switch can also provide redundant data paths in a network, when utilizing Spanning Tree or Rapid Spanning Tree protocols.
Neither scenario would need to connect both switches with a cable. See http://www.intel.com/support/motherboards/server/mfsys25/sb/CS-028603.htm for more details.
