4.4.9 Warm-Up Time Administration
The warm-up time is intended to prevent the PSU 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 a midrange system is driven at low speed as the server starts the
power-on process.
■
Command operation
1. Use the showpowerupdelay (8) command to display the warm-up time
(warmup time).
XSCF> showpowerupdelay
warmup time : 10 minute(s)
wait time : 20 minute(s)
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."
<Example> The warm-up time is set to 5 min.
XSCF> setpowerupdelay -c warmup -s 5
3. 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.
Caution – IMPORTANT - When the power is turned on from the operator panel,
the air-conditioning time and warm-up time that you set are ignored. If you have set
these times and wish to observe them at startup, perform the poweron (8)
command.
