flwo60 is a Sun Ultra 2 workstation with 512 MB of memory installed. It uses a S16D card to interface with the various instruments, and an Aurora 8 port card to interface with various serial devices, such as the guide and tcs pc computers. It contains approximately 42 GB of disk storage on several disk drives.
External devices include a 4mm dat drive (/dev/rst11) and a DLT-IV drive (/dev/rst36). FLWO provides dat tapes. Observers wishing to use DLT tapes need to provide these tapes, although in an emergency, we have a reserve.
Flwo60 runs SOLARIS 2.5.1. It uses the X11 Window system supplied under Sun's Openwin.
Flwo60 and most devices needed for the observer are protected by a UPS, which will produce enough power to run 25 minutes without external power.
If you need to reboot flwo60, please follow this procedure. Exit the Realtime System if possible, and from your login window type godown -r or godown -h. The godown command is a clean way for a normal user to restart the system. The flags -r and -h stand for reboot and hard. If you use the hard option, cycle the power to the cpu, which is a switch located behind flwo60 on the right. Then shut down all remote devices and the monitor.
If flwo60 has been shut down, Turn all remote devices on first, then the cpu, then the monitor.
