RETURNCHARGE <min. batt. charge level> This parameter
specifies what battery percentage charge is necessary before the UPS
will supply power to your equipment after a power down. 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.
BEEPSTATE <alarm beep state> This parameter tells the UPS when
it can sound its audio alarm. These settings are based on discrete
events related to the remaining capacity of the UPS.
0 immediately upon power failure
T power failure + 30 seconds
L low battery power
N never
UPSNAME <string> This is an eight character string. This is the UPS
name that will be stored in the UPS EPROM.
BATTDATE <string> This is an eight character string that is the last
date the batteries were changed.
apcupsd Status Logging
There is a good deal of information available about the UPS and apcupsd’s
status. This document describes the format of that information. Normally
you will get at it via apcaccess, but there are other ways as well.
Status report format
The STATUS output is in ASCII format with a single data value or piece
of information on each line output. Because not all UPSes supply the same
information, the output varies based on the type of UPS that you are using.
In general, if the information is not available for your UPS, the data portion
of the output record will contain an N/A indicating that the information
is not available.
