[CentOS] PCNS for CentOS and APC ups's

Apparently there is only an Itanium client for RHEL according to APC? I need to setup a few boxes to shut down safely and don't know if the PCNS 2.2.3 Linux version will do it? Anyone know why it needs Java as well? (Blegh)

Assuming APC is fairly popular, how do you guys shutdown your CentOS boxes with a UPS with a management card in it?

Thanks!
