When the UPS is off and there is no utility power, use the cold start feature to apply power
to the loads from UPS‘s battery. Press the ON/TEST button until the UPS beeps.
3.8 Shutdown mode:
In shutdown mode the UPS stops supplying power to the load, waiting for return of utility
power. If there is no utility power present, external devices (e.g., servers) connected to the
computer interface can command the UPS to shutdown. This is normally done to preserve
battery capacity after the graceful shutdown of protected servers. The UPS will scroll the
front panel indicators sequentially in shutdown mode.
