UPS module

With the UPS module installed in the BayStack 10 PSU, you power on the unit
by pressing the On button on the front panel for a minimum of 3 seconds.
When you turn the unit on, the buzzer sounds and all the LEDs on the front of the
controller module light for about 15 seconds while the system performs a self-test.
When the self-test is successfully completed, 000 appears in the error code box,
the buzzer goes off, and the LEDs light appropriately. (For information about the
LEDs, refer to "LEDs" on page 18. If 000 does not appear in the error code box,
refer to "Error codes" on page 20.) Initialization is complete.
To configure and manage the BayStack 10 PSU following initialization, refer to
Chapter 3, "Managing the BayStack 10 PSU," on page 59.
