Abstract
A method and a computer program product for detecting link status in a blade system are provided. The method and computer program product provide for generating a first pattern of characters at a server blade of the blade system, transmitting the first pattern of characters from the server blade to an Ethernet switch of the blade system, and comparing a second pattern of characters to the first pattern of characters to determine whether a link from the Ethernet switch to a network is active in response to the server blade receiving the second pattern of characters from the Ethernet switch.
