N2 - The particle identification system ASHIPH (Aerogel, SHifter, PHotomultiplier) has been working in the KEDR experiment at VEPP-4M collider (Budker INP, Novosibirsk) since 2014. The system consists of 160 counters arranged in two layers and covers the 96% of the solid angle. Two layer system permits to use different approaches for π/K separation. Three such approaches are described. The status of the system is presented. Main system parameters such as BhaBha suppression factor, π/K separation power, relativistic particle detection efficiency were measured with help of cosmic particles and experimental data collected at the peak of J/ψ-meson. π/K separation in the momentum range from 0.95 to 1.45GeV/c is better than 4σ. Monte-Carlo simulation procedures are described and results are presented as well.
