Just a little bit of information on connecting a UPS to a Sun
Blade 100. It took me a while to gater all of the information I
needed from usenet so this might save somebody some time - the
information is available, but does need to be tracked down.
UPS Model: APC - Smart-UPS (SU620INET - 230V/AC)
The Smart UPS models are best supported by the S/W
and is probably the only one to consider. Downside is
that it does have a bigger price tag.
Software required: ACP UPS Daemon
There is some software supplied with the Smart-UPS
but I did not like the look of it. They do have a
product called PowerChute Plus which is given away
for Windows and sold for $$ on Solaris - this is the
kind of policy that I very much dislike and feel that
everything should be supplied with the product -
especially when I am on a Sun Blade !.
To connect to the UPS to the Blade via serial then you need
to connect on "ttyb" - the 2nd serial port. There is no 2nd
serial external connection on the Blade so you need to make
one using a spare PCI slot.
A second serial port header is located on the riser board at
J13 - I took information on the pin-out from the "Sun Blade
150 Service Manual" (June 2002) - Sun document 816-4379-10;
Appendix B5. You will need a DB9 serial connector to IDE-10
mounted in a PCI slot - I took mine from a very old 33DX PC
which had the correct connections and gender as "ttya" i.e.
IDE/1 - DB9/1
IDE/2 - DB9/6
IDE/3 - DB9/2
IDE/4 - DB9/7
IDE/5 - DB9/3
IDE/6 - DB9/8
IDE/7 - DB9/4
IDE/8 - DB9/9
IDE/9 - DB9/5
Check these yourself do not rely on me typing them in
correctly. Given a ribbon connector of the correct type - a
visual inspection of the back of the DB9 connector should
reveal odd/even wires being connected to upper/lower rows (it
looks very tidy). Any crossing of wires and you have the
wrong inter-connect (could re-solder them to fix).
The standard cable supplied with the Smart-UPS may be used
for connection to this second serial port.
Follow the build, install and test instructions in the
EXCELLENT documentation supplied with the apcupsd software
(on-line or PDF). Use the CD supplied with the UPS as a
coaster for your coffee as you install and configure your
The only issue I had post install was that the incorrect
version of "shutdown" was bing used in the "apccontrol" file
- possibly because I omitted to get my configuration settings
correct when I built the software. Make sure that
"/usr/sbin/shutdown" is used as opposed to the one in
"/usr/ucb/". This fault is apparent when you run the tests as
a notification of shutdown is issued and nothing happens.
For the people who wrote, support and maintain "apcupsd" a big
Thank You! - good stuff.
