Hi, just testing with a HP R1500 XR (answers as Powerware) with SNMP/Serial Port Card using SNMP I found: 1st: The batt status 1.3.6.1.4.1.534.1.2.5.0 goes away after some time. Isn't visible in a snmpwalk anymore, seems to be a bug in the card. 2nd: The ups turns into "resting" 48h after battery is full. It turns off the fan, the batt voltage lowers a little, it seems, avoiding permanent charging to increase life time. 3rd: Because the fan is turned off, the ambient temperature rises to 61 ?C an decreases lifetime:-) I had to do some changes in the mibs to get all relevant data: { "input.voltage", 0, 1.0, PW_OID_IN_VOLTAGE ".1", "", SU_INPUT_1, NULL }, { "input.current", 0, 0.1, PW_OID_IN_CURRENT ".1", "", SU_INPUT_1, NULL }, Must get ".1" there, as it is in output.voltage/current. (The input current isn't returned, but I think it should be right with .1 there...) TestBattery misses the .0 at the end: #define PW_OID_BATTEST_START "1.3.6.1.4.1.534.1.8.1.0" And by the way, the RFC1628-way of initiating tests works (by hand using snmpget [SpinLock]/snmpset) with this ups, too. And I took the ups status from ietf: { "ups.status", ST_FLAG_STRING, SU_INFOSIZE, IETF_OID_POWER_STATUS, "OFF", SU_STATUS_PWR, &ietf_pwr_info[0] }, because 1.3.6.1.4.1.534.1.4.5.0 isn't answerd by the card.
