Chapter 4 Operation of the Server 4-21
4.4.9 Warm-Up Time Administration
The warm-up time is intended to prevent the power supply unit and the fan from
running until the power supply environments of peripheral units are prepared after
the server starts the power-on processing. Once the warm-up time is set, the
OpenBoot PROM will start after the server power supply is turned on, the power-on
processing starts, and the set warm-up time elapses.
Note – The fan in an M3000/M4000/M5000 server is driven at low speed as the
server starts the power-on process.
â– Command operation
1. Use the showpowerupdelay(8) command to display the warm-up time (warmup
time).
2. Use the setpowerupdelay(8) command to set the warm-up time. Set the
warm-up time from 0 to 255 (min). The default is "0 min."
3. Use the showpowerupdelay(8) command to confirm the setting. Also, to apply
the setting, turning on the server power supply.
4. When turning on the server power supply the next time, please confirm that it
takes more time than usually by checking the amount of time it takes from the
power on until the time when the first Power On Self Test (POST) start message
is displayed.
Note – Once the air-conditioning time is set, the warm-up time will be valid after
the power is turned on and the air-conditioning time elapses.The air-conditioning
time and the warm-up time are also valid when the power is turned on at the power
recovery after the power failure.
