Problems using shutdown -u command
I have a smart-ups connected to my OS X Snow Leopard server ver. 10.6. Based on the docs and forums I read, I have been trying to use the software provided by APC, PCNS. I have also tried to just use the UPS communications cable provided and use the OS' "UPS options". Neither of them work exactly how I need them to.
Here are the issues:
1. If I use the UPS options built in the server, it performs a soft shutdown. Once power is restored to the UPS, the server does not turn back on even though the option is set to power back on after a power outtage. (I understand this because the server had a soft shutdown and not a hard or dirty shurdown which causes the server to reboot once power is restored.
2. If I use PCNS (provided by APC), it will perform a soft shutdown but once again, it will not restart once power is restored to the UPS. There is a doc. mentioning on how to "fix" this. I change the shutdown command initiated by PCNS. The only thing this does is allow for a hard or dirty shutdown. Great, now it reboots once power is restored to the UPS... Problem is, I still need to have a soft shutdown so my VM's will shutdown properly.
3. The command I change from APC is a script that calls for the OS shutdown. The default is shutdown -h now. According to APC, I change this to shutdown -f now. (I never saw the -f option in any man page or Apple doc.) I did find one posting and also in several docs about the -u option. The problem here is that it seems to now work.
4. I perform a shutdown command with the -u command and it will not halt the power supplies for 5 min. before shutting down. If I try the command sudo shutdown -u the response is that I am missing a required option such as -h or -r.
So, I am at an impasse. I need to have my OS X server perform a soft shutdown AND power back up after power has been restored. Right now, it seems I can have either or, and that is not a very enticing resolution....
Any suggestions are most welcome. THanks!

apcsmart
APCSMART(8) Network UPS Tools (NUT) APCSMART(8) NAME
apcsmart - Driver for American Power Conversion Smart Protocol UPS equipment NOTE
This man page only documents the hardware-specific features of the apcsmart driver. For information about the core driver, see nutups- drv(8). SUPPORTED HARDWARE
apcsmart should recognize all APC models that use a serial protocol at 2400 bps. This is primarily the Smart-UPS and Matrix-UPS lines, but some Back-UPS Pro models are also supported. Some older hardware may only report a handful of variables. This is usually not a bug - they just don't support anything else. CABLING
This driver expects to see a 940-0024C cable or a clone by default. You can switch to the 940-0095B dual-mode cable support with the cable= definition described below. If your 940-0024C cable is broken or missing, use this diagram to build a clone: http://www.exploits.org/nut/library/cables/940-0024C.jpg EXTRA ARGUMENTS
This driver supports the following optional settings in the ups.conf(5): cable=940-0095B Configure the serial port for the APC 940-0095B dual-mode cable. sdtype=num Use shutdown type num, according to this table: 0: soft shutdown or powerdown, depending on battery status 1: soft shutdown followed by powerdown 2: instant power off 3: power off with grace period Modes 0 and 1 will power up the load when power returns. Modes 2 and 3 will keep the load turned off when the power returns. BUGS
Some older APC UPS models return bogus data in the status register during a front panel test. This is usually detected and discarded, but some other unexpected values have occasionally slipped through. AUTHOR
