What backup power supply can protect the fs against power outage?

Has anyone experince with power units like the APC Backup-UPS 280 for Linux
running on a 486?  I suppose one cannot guess this since the file structure
(especially in X11) must have its own time characteristic for breakdown. Don

1. power after power outage


I am newbie to Unix and we have one Sparc 5 station running Solaris 2.6, few
days ago there was power outage over week end and on Monday morning when I
tried to boot I got following messages:

The / file system (/dev/rdsk/c0t0d0s0) is being checked.
/dev/rdsk/c0t0d0s0: UNREF DIR  I=818446  OWNER=146 MODE=40777
/dev/rdsk/c0t0d0s0: SIZE=512 MTIME=Mar 5 13:18 2002  (RECONNECTED)

/dev/rdsk/c0t0d0s0: LINK COUNT INCREASING

WARNING - Unable to repair the / filesystem. Run fsck
manually (fsck -F ufs /dev/rdsk/c0t0d0s0). Exit the shell when
done to continue the boot process.

Type control-d to proceed with normal startup,
(or give root password for system maintenance):

I tried to give root password but server doesn't take root password.
When I tried probe-scsi from Ok prompt, I can see all scsi drive.

Any idea will be very much appreciated.
