The effect of diagonal disorder on the upper critical field of the local electron pair system is studied in the framework of the mean field approximation. It is obtained that this kind of disorder greatly changes the temperature behavior of H(c2). Comparing che upper critical field of this system with those of heavy fermion superconductors CeCu2Si2 and UPt3, we find that it could have the similar unusual temperature dependence.
