In this work, we predict the light hadronic decay channels $Y(4230)\to\Lambda\bar{ \Lambda}$ and $\Xi^-\bar{ \Xi}^+$ when treating the $Y(4230)$ as a vector charmonium state. By the hadronic loop mechanism, the branching ratios of the $Y(4230)\to\Lambda\bar{ \Lambda}$ and $\Xi^-\bar{ \Xi}^+$ processes are calculated. In addition, we discuss the possibility of carrying out the search for the signal of the $Y(4230)$ through $\Lambda\bar{ \Lambda}$ and $\Xi^-\bar{ \Xi}^+$ channels from the $e^+e^-$ annihilation. Assuming $Y(4230)$ exist in $\Lambda\bar{ \Lambda}$ and $\Xi^-\bar{ \Xi}^+$ channel, we also present the time-like electromagnetic form factors (EMFFs) at $\sqrt{ s}=m_{ Y(4230)}$.
