Aký záložný zdroj?

[Rainbow]

Vsetko je to line-interactive. Akurat SmartUPS ma na vystupe sinus a BackUPS nie. Preto to bzuci - a preto to s niektorymi zdrojmi s aktivnym PFC vobec nefunguje.

[e1]

To ste ma nepotešili, takto bude výmena viac problémová. No nevadí, pokúsim sa s ním nejako dohodnúť. Inak pozeral som sa že rada Smart nemá vôbec France konektory. Od APC mi ako riešenie ponúkli redukčný kábel Power Cord, C14 to CEE 7/7 Schuko, 0.6m, ale stojí viac ako 30 € a toľko za blbý kábel nedám. Neviete kde by sa dal podobný neznačkový kábel kúpiť lacnejšie?

se da vyrobit - konektor do ups koupis v gme (nebo obdobnym shopu v .sk) a prodluzovacku v libovolnym baumaxu za 80kc

Tohoto som sa chcel vyvarovať, nakoľko na takéto bastlenie som úplný amatér, ale asi nemám na výber. Pravdepodobne pôjdem cestou (resp. niekoho poprosím, lebo ja neviem ani to že ktorá diera je plus a ktorá mínus ) odstrihnutia jedného konca predlžovacieho IEC kábla a k tomu prirobenie 3-tej zásuvky s vypínačom z predlžovačky. Takto totiž nemusím zháňať káble a koncovky.

Dodávateľ mi pristúpil na výmenu. Osobne sa mi pozdáva model APC Smart-UPS SC 1000VA 230V - 2U Rackmount/Tower, ale predajca mi tvrdí že budem potrebovať aspoň APC Smart-UPS 1000VA USB & Serial 230V. Vidím tam v popise rozdiel v tom že lacnejší model má druh priebehu "Iterační aproximace sinusového průběhu" verzus "Sinusoida" pri drahšom. Môže to byť kvôli tomuto? Ak áno, tak to potom už môžem rovno zobrať druhú APC Smart-UPS XL 750VA USB & Serial 230V.

[e1]

Zisťoval som info priamo na technickej podpore APC a potvrdili mi to isté čo povedal môj predajca, takže mám na ceste domov ďalšiu 750-ku XL. Tú čo je pripojená na server som cez noc otestoval, výdrž 74,6 minút, s tým že server sa vypol cca. pri 10% kapacite batérie. Zároveň pri tomto vypnutí som aj zistil divné chovanie v apcupsd, totiž nastavenia boli nasledujúce:

BATTERYLEVEL 2
MINUTES 3
RETURNCHARGE 10

a v momente vypnutia ostaválo asi 10% kapacity batérie čo malo stačiť na 14 minút prevádzky.
Takže problém bude asi s parametrom returnchange, pričom podľa neho by sa server nemal vypínať. Podľa popisu som jeho funkcionalitu pochopil tak že UPS nezapne stroj skôr, ako sa po opätovnom nabehnutí prúdu nedobije batéria na túto hodnotu, ale asi to tak nie je.

## apcupsd.conf v1.1 ##
#
# for apcupsd release 3.14.7 (1 August 2009) - gentoo

#
# ========= General configuration parameters ============
#

# UPSNAME xxx
# Use this to give your UPS a name in log files and such. This
# is particulary useful if you have multiple UPSes. This does not
# set the EEPROM. It should be 8 characters or less.
# UPSNAME

# UPSCABLE <cable>
#   Defines the type of cable connecting the UPS to your computer.
#
#   Possible generic choices for <cable> are:
#     simple, smart, ether, usb
#
#   Or a specific cable model number may be used:
#     940-0119A, 940-0127A, 940-0128A, 940-0020B,
#     940-0020C, 940-0023A, 940-0024B, 940-0024C,

#     940-0095C, M-04-02-2000
#
UPSCABLE usb

# To get apcupsd to work, in addition to defining the cable
# above, you must also define a UPSTYPE, which corresponds to
# the type of UPS you have (see the Description for more details).
# You must also specify a DEVICE, sometimes referred to as a port.
# For USB UPSes, please leave the DEVICE directive blank. For
# other UPS types, you must specify an appropriate port or address.
#
# UPSTYPE   DEVICE           Description
# apcsmart  /dev/tty**       Newer serial character device,
#                            appropriate for SmartUPS models using
#                            a serial cable (not USB).
#
# usb       <BLANK>          Most new UPSes are USB. A blank DEVICE
#                            setting enables autodetection, which is
#                            the best choice for most installations.
#
# net       hostname:port    Network link to a master apcupsd
#                            through apcupsd's Network Information
#                            Server. This is used if you don't have
#                            a UPS directly connected to your computer.
#
# snmp      hostname:port:vendor:community
#                            SNMP Network link to an SNMP-enabled
#                            UPS device. Vendor is the MIB used by
#                            the UPS device: can be "APC", "APC_NOTRAP"
#                            or "RFC" where APC is the powernet MIB,
#                            "APC_NOTRAP" is powernet with SNMP trap
#                            catching disabled, and RFC is the IETF's
#                            rfc1628 UPS-MIB. You usually want "APC".
#                            Port is usually 161. Community is usually
#                            "private".
#
# dumb      /dev/tty**       Old serial character device for use

UPSTYPE usb
DEVICE

# POLLTIME <int>
# Interval (in seconds) at which apcupsd polls the UPS for status. This
# setting applies both to directly-attached UPSes (UPSTYPE apcsmart, usb,
# dumb) and networked UPSes (UPSTYPE net, snmp). Lowering this setting
# will improve apcupsd's responsiveness to certain events at the cost of
# higher CPU utilization. The default of 60 is appropriate for most
# situations.
POLLTIME 15

# LOCKFILE <path to lockfile>
# Path for device lock file. Not used on Win32.
LOCKFILE /var/lock

# SCRIPTDIR <path to script directory>
# Directory in which apccontrol and event scripts are located.
SCRIPTDIR /etc/apcupsd

# PWRFAILDIR <path to powerfail directory>
# Directory in which to write the powerfail flag file. This file
# is created when apcupsd initiates a system shutdown and is
# checked in the OS halt scripts to determine if a killpower
# (turning off UPS output power) is required.
PWRFAILDIR /etc/apcupsd

# NOLOGINDIR <path to nologin directory>
# Directory in which to write the nologin file. The existence
# of this flag file tells the OS to disallow new logins.
NOLOGINDIR /etc


#
# ======== Configuration parameters used during power failures ==========
#

# The ONBATTERYDELAY is the time in seconds from when a power failure
# is detected until we react to it with an onbattery event.
#
# This means that, apccontrol will be called with the powerout argument
# immediately when a power failure is detected.  However, the
# onbattery argument is passed to apccontrol only after the
# ONBATTERYDELAY time.  If you don't want to be annoyed by short
# powerfailures, make sure that apccontrol powerout does nothing
# i.e. comment out the wall.
ONBATTERYDELAY 0

#
# Note: BATTERYLEVEL, MINUTES, and TIMEOUT work in conjunction, so
# the first that occurs will cause the initation of a shutdown.
#

# If during a power failure, the remaining battery percentage
# (as reported by the UPS) is below or equal to BATTERYLEVEL,
# apcupsd will initiate a system shutdown.
BATTERYLEVEL 2

# If during a power failure, the remaining runtime in minutes
# (as calculated internally by the UPS) is below or equal to MINUTES,
# apcupsd, will initiate a system shutdown.
MINUTES 2

# If during a power failure, the UPS has run on batteries for TIMEOUT
# many seconds or longer, apcupsd will initiate a system shutdown.
# A value of 0 disables this timer.
#
# Note, if you have a Smart UPS, you will most likely want to disable
# this timer by setting it to zero. That way, you UPS will continue
# on batteries until either the % charge remaing drops to or below BATTERYLEVEL,
# or the remaining battery runtime drops to or below MINUTES.  Of course,
# if you are testing, setting this to 60 causes a quick system shutdown
# if you pull the power plug.
# If you have an older dumb UPS, you will want to set this to less than
# the time you know you can run on batteries.
TIMEOUT 0

# Time in seconds between annoying users to signoff prior to
# system shutdown. 0 disables.
ANNOY 60

# Initial delay after power failure before warning users to get
# off the system.
ANNOYDELAY 120

# The condition which determines when users are prevented from
# logging in during a power failure.
# NOLOGON <string> [ disable | timeout | percent | minutes | always ]
NOLOGON disable

# If KILLDELAY is non-zero, apcupsd will continue running after a
# shutdown has been requested, and after the specified time in
# seconds attempt to kill the power. This is for use on systems
# where apcupsd cannot regain control after a shutdown.
# KILLDELAY <seconds>  0 disables
KILLDELAY 0

#
# ==== Configuration statements for Network Information Server ====
#

# NETSERVER [ on | off ] on enables, off disables the network
# information server. If netstatus is on, a network information
# server process will be started for serving the STATUS and
# EVENT data over the network (used by CGI programs).
NETSERVER on

# NISIP <dotted notation ip address>
#  IP address on which NIS server will listen for incoming connections.
#  This is useful if your server is multi-homed (has more than one
#  network interface and IP address). Default value is 0.0.0.0 which
#  means any incoming request will be serviced. Alternatively, you can
#  configure this setting to any specific IP address of your server and
#  NIS will listen for connections only on that interface. Use the
#  loopback address (127.0.0.1) to accept connections only from the
#  local machine.
NISIP 0.0.0.0

# NISPORT <port> default is 3551 as registered with the IANA
#  port to use for sending STATUS and EVENTS data over the network.
#  It is not used unless NETSERVER is on. If you change this port,
#  you will need to change the corresponding value in the cgi directory
#  and rebuild the cgi programs.
NISPORT 3551

# If you want the last few EVENTS to be available over the network
# by the network information server, you must define an EVENTSFILE.
EVENTSFILE /var/log/apcupsd.events

# EVENTSFILEMAX <kilobytes>
# By default, the size of the EVENTSFILE will be not be allowed to exceed
# 10 kilobytes.  When the file grows beyond this limit, older EVENTS will
# be removed from the beginning of the file (first in first out).  The
# parameter EVENTSFILEMAX can be set to a different kilobyte value, or set
# to zero to allow the EVENTSFILE to grow without limit.
EVENTSFILEMAX 1024

#
# ========== Configuration statements used if sharing =============
#            a UPS with more than one machine

#
# Remaining items are for ShareUPS (APC expansion card) ONLY
#

# UPSCLASS [ standalone | shareslave | sharemaster ]
# Normally standalone unless you share an UPS using an APC ShareUPS
# card.
UPSCLASS standalone

# UPSMODE [ disable | share ]
# Normally disable unless you share an UPS using an APC ShareUPS card.
UPSMODE disable

#
# ===== Configuration statements to control apcupsd system logging ========
#

# Time interval in seconds between writing the STATUS file; 0 disables
STATTIME 0

# Location of STATUS file (written to only if STATTIME is non-zero)
STATFILE /var/log/apcupsd.status

# LOGSTATS [ on | off ] on enables, off disables
# Note! This generates a lot of output, so if
# you turn this on, be sure that the
# file defined in syslog.conf for LOG_NOTICE is a named pipe.
# You probably do not want this on.
LOGSTATS off

# Time interval in seconds between writing the DATA records to
# the log file. 0 disables.
DATATIME 0

# FACILITY defines the logging facility (class) for logging to syslog..
#          If not specified, it defaults to "daemon". This is useful.
#          if you want to separate the data logged by apcupsd from other
#          programs.
#FACILITY DAEMON

#
# ========== Configuration statements used in updating the UPS EPROM =========
#

#
# These statements are used only by apctest when choosing "Set EEPROM with conf
# file values" from the EEPROM menu. THESE STATEMENTS HAVE NO EFFECT ON APCUPSD.
#

# UPS name, max 8 characters.

Ďalšia vec je nezrovnalosť v spotrebe. Zásuvkový merač spotreby mi ukazoval v idle 135W, apsupsd zase cca. 29% maximálneho príkonu, čo by malo byť cca. 175W. Pri záťaži je rozdiel 180W vs. 225W. Hodnoty ktoré udáva graf na stránke APC nedosahujem.

Mereni UPSky je orientacni (a on ten merak asi taky nebude zazrak), takze to nemuzes brat nijak vazne. Co se konfigurace tyce, chapu to tak, ze ke zhozeni stroje dojde pokud je dosazena alespon jedna z nastavenych hranic => mas ze pri 10% a ze to muze bezet jeste dyl nez 3 minuty je pak nepodstatny. Kazdopadne se nespolehej na to, ze UPSka presne vi, na jak dlouho ji baterka vydrzi, UPSka neni zalozni zdroj, UPSka je zdroj kterej ma preklenout kratkej vypadek, pripadne cas ke korektnimu vypnuti.
