Under normal apcupsd operations (no --configure option), apcupsd
will read the value stored in the UPS and display it in the STATUS
output.
WAKEUP <set wakeup delay> The UPS power restart delay value in
[0,60,180,300] in seconds after the UPS has shut down during a power
failure. This is to prevent the power from coming back on too quickly
after a power down, and is important for those who have high rpm
drives that need to spin down before powering them up again. Some
older SCSI models are very sensitive to this problem. Default is zero.
This value is written to the UPS EPROM when the --configure
option is specified.
Under normal apcupsd operations (no --configure option), apcupsd
will read the value stored in the UPS and display it in the STATUS
output.
SLEEP <set sleep delay> The UPS delay or grace period in
[20,180,300,600] seconds before the UPS cuts the power to your equip-
ment. The default is 20 seconds. This value is written to the UPS
EPROM when the --configure option is specified.
Under normal apcupsdoperations (no --configure option), apcupsd
will read the value stored in the UPS and display it in the STATUS
output.
LOTRANSFER <lower limit of ups batt. transfer> This sets the
low line voltage point at which to switch over to batteries. Differ-
ent values are permitted based on the UPS model, classification, and
manufacture date. Use apcaccess eeprom to show you which values
are permitted. This value is written to the UPS EPROM when the
--configure option is specified.
Under normal apcupsdoperations (no --configure option), apcupsd
will read the value stored in the UPS and display it in the STATUS
output.
HITRANSFER <upper limit of ups batt. transfer> This sets the
high line voltage point to switch over to batteries. Different values are
permitted based on the UPS model, classification, and manufacture
date. Use apcaccess eeprom to show you which values are permitted.
This value is written to the UPS EPROM when the --configure
option is specified.
Under normal apcupsdoperations (no --configure option), apcupsd
will read the value stored in the UPS and display it in the STATUS
output.
