Inspired by the newly observed DsJ(3040)+ state, in this work we systemically study the two-body strong decays of P-wave charmed-strange mesons with the first radial excitation. Under the assignment of 1+(jP=(1)/(2)+), i.e. the first radial excitation of Ds1(2460)+, we find that the width of DsJ(3040)+ is close to the lower limit of the BABAR measurement. This indicates that it is reasonable to interpret DsJ(3040)+ as the first radial excitation of Ds1(2460)+. Our calculation further predicts that 0^\ensuremath-+1^\ensuremath- channels, e.g., D+K*0, D0K*+, and Ds+\ensuremathφ, are important for the search for DsJ(3040)+. To help future experiments find the remaining three P-wave charmed-strange mesons with the first radial excitation, we present the predictions for the strong decays of these three P-wave charmed-strange mesons.
