Re: UPS battery replacement causes an . . . interruption

Understood.  My point was that if you did have a generator then the UPS would only need to run for the length of time that it would take for the generator to kick in and switch over.  That would likely be less than a minute.

A generator (which we do not have) has no bearing here.  The UPS has to be
shut down.

Yes it is "planned" but I'm making them do it at 6:30am.

  It's a question of planned vs unplanned interruption.  Besides, if you
have a generator you should only need a minute until it kicks in.

  Our IBM i has been in a data center for several years.  Since we no longer
needed the Nfinity UPS for such a small load (Sonicwalls, DNS servers,
switches, etc) we installed a rackmounted Tripp Lite SU1500RTXL2Ua with an
internal battery and an external battery.  This gives us just under 2 hours
in a power outage.

Imagine my surprise, now that it's time to replace the batteries, the
internal battery *is* hot swappable, but the external battery is *not* hot
swappable.  So we have to shut down the rack to replace the batteries.  If
anything, I would have expected the opposite.

It is ironic that replacing the batteries in an "uninterruptible" system
causes an interruption.
