This is the card im talking about: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AP9630&tab=models 

But I guess it does not support master protocol. It supports SNMP is jsut for monitoring isnt it? Can I send shutdown commands over
SNMP?

Thanks

apcsmart supports only serial communication. apcmaster and apcmastersnmp work over TCP/IP. Perhaps this UPS also supports snmp,
maybe that's worth a try. What exactly is that extra management card? Does it support master protocol?
