Hello again,
I have a Sola 305 (aka Powerware 3110) here connected via a serial
INT-0051 cable which I am trying to get working with nut. The
driver.list file indicates that nut supports the Sola 305 when connected
via the INT-0025C cable using the genericups driver with upstype set to
7 but it does not mention the INT-0051.
I was able to use the "Basic CheckUPS II" utility provided by Best
Power
to verify that the UPS is connected to the serial and is communicating
properly (after making a very small modification to the source
(inserting a usleep)). After verifying that the connection was okay, I
hunted around on the net and found the following document:
http://ftp.nluug.nl/os/Linux/distr/smeserver/contribs/rmitchell/smeserver/howto/powstatd
HOWTO for sme server.htm
It indicates that the settings to use when connected via a INT-0025C
are:
init0 dsr init0 rng init0 dtr init1 rts fail cts,0 low dcd,0 kill dtr,1
This seems to agree with the definition of type 7 in genericups.h:
/* Type 7 */
{ "CyberPower",
"Power99",
"CyberPower Power99",
TIOCM_RTS, /* cable power: RTS */
TIOCM_CTS, TIOCM_CTS, /* online: CTS on */
TIOCM_CD, 0, /* low battery: CD off */
TIOCM_DTR /* shutdown: set DTR */
},
The powstatd document then defines the settings to use when connecting
using a INT-0051 as:
init0 rts init0 rng init0 dsr init1 dtr fail cts,0 low dcd,0 kill rts,1
My guesstimate is that this would correspond to an entry in the upstab
something like:
{ "Sola",
"305",
"with INT-0051 cable",
TIOCM_DTR, /* cable power: DTR */
TIOCM_CTS, TIOCM_CTS, /* online: CTS on */
TIOCM_CD, 0, /* low battery: CD off */
TIOCM_RTS /* shutdown: set RTS */
},
This matches the definition of type 6 ("Best Patriot (INT51 cable)")
and
type 19 ("Fideltronik Ares Series"). I have set upstype to 6 and nut
appears to be happy, although this UPS is attached to a system that I
can't afford to shut down to perform a full test. The fact that the
Best Patriot configuration is specified as INT51 (as opposed to INT0051)
seems congruent to me.
Is anyone else using a similar configuration? If this setup is known to
work, would it be possible to add a new entry to drivers.list for Sola
305s connected via INT-0051?
Thanks,
Daniel Burr
