WARNING
The "POWER CYCLE REQUEST", “POWER CYCLE DELAY” and “POWER OFF DURATION” for
Enclosure are defined in the bit7~6, byte2, bit5~0, byte2 and bit7~2, byte3 of the "Enclosure
control element" in the SES specification. Set “POWER CYCLE REQUEST” as 01b to begin a
power cycle in minutes set by “POWER CYCLE DELAY” (1~60 minutes, 0 for
beginning power cycle immediately) and keep off for minutes set by “POWER OFF
DURATION” (set 1~60 minutes, 0 for 10 seconds and 63 for keeping off). A request to begin
a power cycle while a previous request is still active should override the previous request.
Set
“POWER CYCLE REQUEST” as 10b to cancel any scheduled power cycle.
