[SBE] Net Guardian SNMP Monitoring

[Londono Echeverry, Roberto]

Hi Kim

Here is definition SNMP.

The Simple Network Management Protocol (SNMP) forms part of the internet
protocol suite as defined by the Internet Engineering Task Force (IETF).
SNMP is used in network management systems to monitor network-attached
devices for conditions that warrant administrative attention. It
consists of a set of standards for network management, including an
Application Layer protocol, a database schema, and a set of data
objects.
Reference

When you said " I tried to connect the Net Guardian to my APC Smart UPS
1000 via the RS232
connector."  You can't  use this protocol to Management your UPS  to use
RS232 you need to connect by RJ 45 Like Al Muick said " you may need a
crossover

> cable to bypass the need for connecting them through a network.  (You

can

> tell by the lack of activity on the NIC cards when they are jacked

network. 
Many problem UPS are Batteries or protections check that before you put
trash.

Thanks for the quick response Al. I'm so glad I finally found someone
that
might be able to help me with this.

I tried to connect the Net Guardian to my APC Smart UPS 1000 via the
RS232
connector. The manual for the UPS said it was SNMP enabled, but I was
unable
to get the Net Guardian to "see" the UPS. At the time that UPS was the
only
thing I had in my shop with SNMP. Sadly, that UPS was killed in a recent
electrical storm. I didn't think of using a crossover cable or null
modem
cable at the time, that may have been my problem. Now I need to find a
piece
of inexpensive equipment, or borrow something from a client so I can
continue to experiment with SNMP.  What would you recommend to test
with? I
have a few consumer (home network) linksys routers laying around, do you
think one of those would work for my testing purposes?
