APC's new SMX SMT SURTD Signalling system[edit]

Can someone elaborate on APC wonderful new signalling system that no longer works with Microsoft's Control Panel > Power Options UPS tab, but requires 100 MB of APC's bloatware (including 85 MB of Java) just to shut down a server cleanly when supply power is lost. Installing 100 MB of dubious software on a company's crown jewels - the Enterprise Resource Planning (ERP) server is just crap. I bought two new SMT3000RM12U at the cost of £2000 and now find myself in a bind. APC's international technical support having never heard of controlling APC UPS equipment using built in Windows utilities - unbelievable! — Preceding unsigned comment added by 87.83.230.50 (talk) 07:54, 9 April 2013 (UTC)[reply]

APC tech support is pretty good, you might just have to go back and forth a few times until you get past level 1 support. I'd be very surprised if they have broken backwards compatibility. Failing that, tell your account manager/salesperson you'll return them if he can't get you the answer you want, that works fantastically well. You can also try asking on a mailing list for one of the open source UPS programs. They are likely to know if the new devices can be made to work with existing software. -- Malvineous (talk) 08:19, 9 April 2013 (UTC)[reply]

Thanks Malvineous, it would appear that APC are keeping their new signalling system under their hat. Hopefully this is comment section may warn people replacing old equipment that things are not simple! NUT (Network UPS Tools) part of the Opensource Software Community has complained that APC will not co-operate with them with this new system. Anyway it would appear that to revert the new range of UPS's to the traditional signalling system, required an extra module is required (AP9620) costing another £40. Sadly I have found APC technical support absolutely hopeless, for such a supposedly large player. Can anyone explain UPS hardware requires a minimum of 100 MB of software to shut-down a server via RS232 (Serial) communications. Information on the new signalling system would enable people to develop better simpler shutdown software.

SUA vs SMT models[edit]

Does anyone have more info on differences between the older SUA models and the newer SMT models?

One difference I've been told is that the old ones trickle-charge the batteries at a float voltage once they're full but due to problems (presumably due to age), the float voltage starts to drift and overcharges the batteries unless they're manually recalibrated or, in some cases, have the microcontroller parameters changed (see http://www.jjoseph.org/notes/apc_smartups_battery_float_voltage, http://web.archive.org/web/20131224040214/http://www.apc-fix.com:80/page.php?al=apcfix)

Supposedly the SMT ones no longer trickle-charge but instead do on-again/off-again cyclic charging but there's precious little info floating around to back this up or give any detail.

The only other difference I'm aware of is the SMTs have an LCD control panel and more buttons.

Anyone able to expand on this to make it article worthy? — Preceding unsigned comment added by 77.101.174.194 (talk) 10:06, 12 April 2013 (UTC)[reply]

USB Cable[edit]

Does anyone know about / have a reference for the wiring of the 940-273A cable? The link to USB cables covers the 940-127 series - is the 940-273A different? APC says it's an RJ45 (though I suspect it may be an RJ50 - I don't have the UPS to look at the female connector). I've had no luck with search engines. Many thanks in advance.

The USB cable has a keyed 10P10C RJ45 (rather than the "standard" 8P8C RJ45 common to Ethernet networking) at the one end but only 4 pins are actually cabled.

Bad Links[edit]

The link for the AP9606 (http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AP9606) is 404. I suspect other links are, as well.
