.SH NAME
apcupsd \- daemon for most APC's UPS for Linux
.SH SYNOPSIS
.B /sbin/apcupsd
.br
.B /etc/apcupsd/apccontrol
.br
.B /etc/apcupsd/apcupsd.conf
.br
.B /sbin/apcaccess
.br
.B /sbin/apcnetd
.br
.SH DESCRIPTION
.LP
This daemon can be used for controlling the APC SmartUPS. During a power
failure, "apcupsd" will inform the users about the power failure and
that a shutdown may occur. If power is not restored, a system shutdown
will follow when the battery is exausted, a timeout (seconds) expires,
or runtime expires based on internal APC calculations determined by
power consumption rates. If the power is restored before one of the
above shutdown conditions is met, "apcupsd" will inform users about this
fact.
The shutdown is made by script calls to "/etc/apcupsd/apccontrol", which
is called by "apcupsd". Consequently, no changes to /etc/inittab are necessary.
There is no communication between "apcupsd" and init(1) process.
Apcupsd modifies the halt script so that at the end of the shutdown
process, apcupsd will be re-executed in order to power off the UPS.
.LP
The "apcupsd" daemon now supports two networking modes that function
independently, but if desired at the same time.
Most users will probably enable the first network mode, which
permits apcupsd to serve status and event information
to clients over the network.
The second networking mode is for multiple networked machines that are
powered by the same UPS. In this mode, one machine is configured as a
master with the UPS attached to the serial port. The other machines
(max. 20) powered by the same UPS are configured as slaves. The master
has a network connection with the slaves and sends them information
about the UPS status.
.LP
RedHat and S.u.S.E. versions of Linux have direct install support. All
other "FLAVORS" of Linux will need some fussing with to get the install
correct.
.SH OPTIONS

.SH CONFIGURATION
It may be necessary to change the configuration information in the file
"/etc/apcupsd/apcupsd.conf" to meet your needs and to correspond to your
configuration. This file is a plain ASCII file and you can use your
favorite editor to change it.
.LP
Configuration commands in
.B /etc/apcupsd/apcupsd.conf
are:
.LP
.SS GENERAL CONFIGURATION COMMANDS
.LP
.B UPSCABLE
-- <type of cable you are using>
.br
[ simple | 940-0020B | 940-0023A (broken) ]
.br
[ smart | 940-0024B | 940-0024C ]
.br
[ 940-0095A | 940-0095C ]
.br
[ ether ]
.LP
.B UPSTYPE
-- <Type of APCC UPS you have>
.br
[ backups | sharebasic ] : Simple
.br
[ netups ] : Network Simple Signals
.br
[ backupspro | smartvsups | newbackupspro ] : SubSmart
.br
[ smartups | matrixups | sharesmart ] : Smart
.LP
[ backups | netups | backupspro | smartvsups ] and
.br
[ newbackupspro | smartups | matrixups ] are tested.
.br
[ sharebasic | sharesmart ] models are being tested.
.LP
.B DEVICE
-- <name of serial port>
.br
Please specify which device is used for UPS communication.
The default is /dev/ttyS[0|1|2|3].
.LP
.B LOCKFILE
-- <path to lockfile>
.br
By supplying this argument, "apcupsd" tries to create a lockfile
for the serial port in the specified directory.
.LP
.SS CONFIGURATION COMMANDS USED BY THE NETWORK INFORMATION SERVER
.LP
.B NETSTATUS
[on | off]
.br
This configuration command turns the network information server
on or off. If it is on, apcupsd will spawn a child process that
serves STATUS and EVENTS information over the network. This
information is currently used by the Web based CGI programs.
The default is on. In some cases, for added security, you may
want to invoke a separate information server daemon from the inetd
daemon. In this case, NETSTATUS should be off.
.LP
.B STATUSPORT
<port>
.br
This configuration command specifies the port to be used by the
apcupsd server. The default is 7000. If you change this port,
you must manually change the #define SERV_TCP_PORT in
cgi/upsfetch.c and rebuild the CGI programs.
.LP
.B EVENTFILE
<filename>
.br
If you want the apcupsd network information server to provide
the last 10 events via the network, you must specify a
file where apcupsd will save these events. The default is:
/etc/apcupsd/apcupsd.events. Currently, apcupsd will save
at most the last 50 events. When more than 50 events are
recorded and a network request for the events arrives,
the network server will truncate the file to
the most recent 10 events. Consequently this file
will not grow indefinitely as long as the events are
checked from time to time.
.LP
.SS CONFIGURATION COMMANDS USED TO CONTROL SYSTEM LOGGING
.LP
.B STATTIME
.LP
.B STATFILE
.LP
.B DATATIME
.LP
.B FACILITY
.LP
.B CONFIGUATION COMMANDS USED DURING POWER FAILURES
.LP
.B ANNOY
-- <time in seconds>
.br
Please specify the time in seconds between messages requesting
logged in users to get off the system. This timer starts only when
the UPS is running on batteries. The default is 300 seconds
(5 minutes).
.LP
.B ANNOYDELAY
-- <time in seconds>
.br
Please specify delay time in seconds before apcupsd begins requesting
logged in users to get off the system. This timer starts
only after the UPS is running on batteries.
This timer is reset when the power returns. The default
is 60 seconds. That is the first warning to log off the
system occurs after 60 seconds on batteries.
.LP
.B NOLOGON
-- <specifies when apcupsd should create the nologon file>
.br
[ disable | timeout | percent | minutes | always ] are valid types.
Based on Ten (10) percent of a setting. This allows one to define the
point when the /etc/nologin file is added. This is important for
allowing systems with BIG UPSes to run as normally until the system
administrator determines the need for dumping users. The feature also
allows the system administrator to hold the "ANNOY" factor until the
/etc/nologin file is added.
.B disable
prevents apcupsd from creating the nologin file.
.B timeout
specifies a specific wait time before creating the nologin file.
.B percent
specifies the percent battery charge remaining before creating
the nologin file.
.B minutes
specifies the battery runtime remaining before creating the
nologin file.
.B always
causes the nologin file to be immediately created on a power
failure.
.LP
.B BATTERYLEVEL
-- <percent of battery>
.br
If BATTERYLEVEL is specified, during a power failure, apcupsd will
shutdown the system when the remaining battery charge falls below the
specified percentage. The default is 5.
.LP
.B MINUTES
-- <battery runtime in minutes>
.br
If MINUTES is specified, during a power failure, apcupsd will
shutdown the system when the remaining remaining runtime on batteries
as internally calculated by the UPS
falls below the time specified. The default is 3.
.LP
.B TIMEOUT
-- <time in seconds>
.br
After a power failure, the system will be shutdown after TIMEOUT seconds
have expired. Normally for SMARTUPSes, this should be zero so that the
shutdown time will be determined by the battery level or remaining runtime
(see above). This command is useful for dumb UPSes that do not report
battery level or the remaining runtime. It is also useful for
testing apcupsd in that you can force a rapid shutdown by setting
a small value (e.g. 60) and pulling the plug to the UPS.
The timeout for the master is always 30 seconds longer than slaves.
.B TIMEOUT, BATTERYLEVEL, and MINUTES
can be set together without problems. The daemon will react to the
first case or test that is valid. Normally SmartUPS users will set
.B TIMEOUT
to zero so that the system is shutdown depending on the
percentage battery charge remaining
.B (BATTERYLEVEL)
or the remaining battery runtime
.B (MINUTES).
.LP
.SS CONFIGURATION COMMANDS USED TO SET THE UPS EPROM
The values specified with the following commands are only
used if the
.B --configure
option is specified on the apcupsd command line, and the UPS is capable
of internal EPROM programming. In that case, apcupsd attempts to set
the values into the UPSes EPROM.
Under normal operations, the values for these parameters specified
in the configuration file are not used. Instead, they are
read from the UPS EPROM by apcupsd.
.LP
.B SENSITIVITY
-- <sets sensitiviy level>
.br
(H)igh, (M)edium, (L)ow
.br
This value determine how sensitive the UPS is to the mains
quality and voltage fluxuations. The more sensitive it is, the
quicker the UPS will switch to battery power when the mains line
quality is bad. Normally, this should be set to H, but if
you find your UPS switching to batteries frequently, you might
want to try a less sensitive setting, providing that your
computer equipment tolerates the poor quality mains.
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 store in the UPS and display it in the
STATUS output.
.LP
.B WAKEUP
-- <set wakeup delay>
.br
The power restart delay value in [0,60,180,300] in seconds
after the UPS shuts 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 spindown 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 store in the UPS and display it in the
STATUS output.
.LP
.B SLEEP
-- <set sleep delay>
.br
Delay in [20,180,300,600] seconds before the actual killpower event.
The default is 20. 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 store in the UPS and display it in the
STATUS output.
.LP
.B LOTRANSFER
-- <sets lower limit of ups batt. transfer>
.br
This sets the low line voltage point to switch over to batteries.
There are four values that can be selected, but they vary based on
the UPS model, classification, and manufacture date. Thus a value
ranging from 0-3 are assigned the learned and bubble sorted values.
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 store in the UPS and display it in the
STATUS output.
.LP
.B HITRANSFER
-- <sets upper limit of ups batt. transfer>
.br
This sets the high line voltage point to switch over to batteries.
.br
There are four values that can be selected, but they vary based on
the UPS model, classification, and manufacture date. Thus a value
ranging from 0-3 are assigned the learned and bubble sorted values.
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 store in the UPS and display it in the
STATUS output.
.LP
.B RETURNCHARGE
-- <sets min. batt. charge level>
.br
This parameter specifies what battery percentage
charge is necessary before
the UPS will supply power to your equipment after a power down.
There are four values that can be selected, but they vary based on
the UPS model, classification, and manufacture date. Thus a value
ranging from 0-3 are assigned the learned and bubble sorted values.
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 store in the UPS and display it in the
STATUS output.
.LP
.B BEEPSTATE
-- <sets alarm beep state>
.br
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.
.B 0
immediately upon power failure
.B T
power failure + 30 seconds
.B L
low battery power
.B N
never
.LP
.B UPSNAME
-- <string>
.br
This is normally an eight character string, but it currently
only handles seven. This is the UPS name that will be stored
in the UPS EPROM.
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 store in the UPS and display it in the
STATUS output.
.LP
.SS CONFIGURATION COMMANDS FOR SHARING A UPS
.LP
.B UPSCLASS
-- <class of operation>
.br
[ standalone | shareslave | sharemaster ] and
.br
[ netslave | netmaster ] are valid types.
.br
[ standalone | netslave | netmaster ] are tested classes.
.br
[ shareslave | sharemaster ] classes are being tested.
.LP
The default is "standalone" and should be used for
all machines powered by the UPS and having a serial port
connection to the UPS, but where there are no other computers
dependent power from the same UPS. This is the "normal" case.
Use "netmaster", if and only if you have a serial port connection
to the UPS and there are other machines deriving power from the
same UPS.
Use "netslave" if and only if you have no serial port connection
to the UPS, but you derive power from it.
Use "shareslave" if and
only if you are using a ShareUPS and connected to a BASIC Port with
Simple Signal.
Use "sharemaster", if and only if you are using a
ShareUPS and connected to the ADVANCED Port Smart Signal control.
.LP
.B UPSMODE --
[ disable | share | net | sharenet ] are valid types.
.br
.LP
[ disable | net ] are the only known and tested classes.
.br
[ share | sharenet ] classes are being tested.
.LP
BETA [ share ] For two or seven (2/7) additional simple signal
ports on a SmartAccessories(tm) (internal/external box) for SmartUPSes.
.LP
.LP
.B NETTIME
-- <time in seconds>
.br
The rate in seconds that broadcasts information to Slave machines.
This rate is reset if there is a power state change. This value
is now passed to the slaves to sync. the openning of a socket
by the slave for the master.
.LP
.B NETPORT
-- <TCP|UDP port number>
.br
This unix service port number must be set in the /etc/services file
as follows:
.br
tab tab(spacejunk) tab tab
.br
name (stuff)/xxp #
.br
.br
apcupsd NETPORT/tcp #
.br
apcupsd NETPORT/udp #
.LP
.B MASTER
-- <name of master> for Slave machine.
.br
The name of the master which is authorized to send commands to this slave.
.LP
.B SLAVE
-- <name of slave(s)> for Master machine.
.br
The name of the slave machine attached to the master.
There can be max. 20 slaves attached to one master.
.LP
.B USERMAGIC
-- < user defined magic> for Slave machine.
.br
The second level of magic security. It must be (17) characters long
without spaces. This is passed to the master machine during
initialization of sockets. This string should be different for
each and every slave on the network.
.SH SMARTUPS
If you start getting the follow message:
.B Emergency -- Batteries Have Failed!
.br
.B Change Them NOW!
Act upon it quickly. It means what it says.
Also, not all "SmartUPS" models are eqaully smart. A non-NET or old
class of "SmartUPS" has a subset of the full UPSlink(TM) language,
and can not be polled for its control codes.
.LP
.SH SHAREUPS
Special note for ShareUPS users,
.B TIMEOUT, BATTERYLEVEL, and MINUTES
are disabled or set to default values. Currently, there is not a known
way of early signals to be sent to BASIC Ports. MINUTES are set to 0.
.SH Hewlett Packard
The HP PowerTrust 2997A UPS has been tested as a "smartups" with cable
Hewlett Packard part number 5061-2575 as "CUSTOM-SMART".
.SH CABLES
.br
First, you will need the cable between APC Smart UPS and PC computer
running Linux. You can use either the special cable which is enclosed with
the PowerChute (TM) software or you can make your own cable connected as
follows:
.LP
SMART-CUSTOM
.br
PC (9 pin) APC (9 pin)
.br
2 RxD 2
.br
3 TxD 1
.br
5 GND 9
.LP
SIMPLE-CUSTOM
.br
DB9/25F PC Side DB9M UPS Side
.br
4/20 DTR (5vcc) nc (*)
.br
8/5 CTS (low-batt) 5 (*)
.br
2/3 RxD (other line-fail) 3 (*)
.br
5/7 Ground (Signal) 4
.br
1/8 CD (line-fail from ups) 2
.br
7/4 RTS (shutdown ups) 1
.br
nc/1 Frame/Case Gnd (optional) 9
.LP
List if componets one needs to make this CABLE:
.br
1) One (1) DB9 use solder type connector only.
.br
2) One (1) DB9/25F use solder type connector only.
.br
3) two (2) 4.7K ohm 1/4 watt %5 resistors.
.br
4) one (1) foot of 3/32" (inch) shrink wrap/boot.
.br
5) rosin core solder.
.br
6) three (3) to five (5) feet of 22AWG multi-stranded five
.br
(5) conductor cable.
.LP
First solder both of the resistors into pin# (4) DB9 or (20) DB25 the DTR.
This will be used as the Vcc pull-up voltage for testing the outputs on
any "UPS by APC" ONLY in Simple Signal mode. This may not work on a
BackUPS Pro if the default communications are Smart Signal mode. This
cable is valid for "ShareUPS" BASIC Port mode if there are no other cables
that can be gotten.
.LP
Next bend each of the resistors so that one connects to (8) DB9 or (5) DB25
the CTS (aka battery low signal) and the other to (2) DB9 or (3) DB25 the
RxD (aka another line fail signal). This line is not currently used, but
it will be in the near future.
.LP
(*) 8/5 is also wire to pin# 5 on UPS cable side.
.br
(*) 2/3 is also wire to pin# 3 on UPS cable side.
.br
(*) we use the DTR as our +5 volts power for the circuit.
.LP
If you have one of the following cables supplied by APCC,
.B apcupsd
will support off the shelf cables.
.br
940-0020B Simple Signal Only, all models.
.br
940-0024[B/C] SmartMode Only, SU and BKPro only.
.br
940-0095[A/C] PnP (Plug and Play), all models.
.br
940-0023A Simple Signal UNIX, [BROKEN STILL].
.SH FILES
.B /etc/apcupsd/apcupsd.conf
- configuration file.
.br
.B /etc/apcupsd/apcupsd.status
- STATUS file
.br
.B /etc/apcupsd/apcupsd.events
- where up to the last 50 events are stored
for the network information server.
.SH EVENTS
apcupsd generates events when certain conditions occur
such as a power failure, batteries exhausted, power return,
...
These events are sent to the system log, optionally sent
to the temporary events file (/etc/apcupsd/apcupsd.events),
and they also generate a call to /etc/apcupsd/apccontrol
which in turn will call any scripts you have placed in the
/etc/apcupsd directory.
.SH DATA format
If the DATATIME configuration command is set nonzero,
apcupsd will log a data record at the interval defined
on the DATATIME command. This data record is in a format
similar to the PowerChute data file format.
.SH STATUS format
The STATUS output is in ASCII format and generally there
is a single piece of information on each line output.
The format varies based on the type of UPS that you are using.
