UPS options other than Powertrust for D380

We have a D380 server running 10.20 for disaster recovery in the event we ever needed it. Hardly robust, dual processor, 4 4.3gb HDD, DDS3 tape drive, CD-ROM and external DLT4000 tape drive. Are there any 3rd-party UPS options that anyone could recommend that would provide for graceful shutdown? I've seen APC PowerChute for HP-UX in many weblinks, but have yet to find anyone that actually has the product in stock.

Any help would be appreciated.

Do you already have an UPS?

There is no UPS for the D380. We just completed piecing together the system and a UPS is the last peripheral we need.

In the mid 90s I had (and still have at home) a HP 715 workstation.
after a heavy corruption due to power shortage I had a backups PSU to connect to (just for the AC) but no one would pay for more...
So I tried to figure out a workaround, after working out I had 10 minutes to shutdown the station, I came up writing a script for the cron which pinged my pc every 4 minutes and in case of a failure would do a shutdown... Not as elegant as a real software and port connection, but better than nothing...
