Power unit (160 Series)
The power unit includes 4 power modules inside (5 modules in
the optional redundant power supply, S-NP15PWR-EX). If one
of the power modules fails, the corresponding indicator goes
off.
The S1 and S2 indicate the standby power.
 Lighting either of them shows one of the power cords doesn't
supply the power correctly or one of two standby power
circuits fails. Check if both power cords are surely connected.
 Even if a standby power circuit has failed, the power unit can
properly supply the power to the LED units.
