[Nut-upsuser] snmp-ups sends status "OL OB" on HP R3000 UPS with AF465A management card [UPDATE]

Thu Feb 27 14:25:00 UTC 2014

Additional question: I noticed on the HP Website that the latest version
of "CPQPOWER.MIB" (1.76, dated Sept. 19, 2013) was more recent than the
related file (./drivers/compaq-mib.c) in the NUT driver.

Is the MIB structure as implemented on the management card perhaps no
longer in line with the NUT driver ?

The latest MIB file can be downloaded from the following URL:

<https://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_bd9b6997fbc7fc515f4cf4626f5c8d01=wsrp-navigationalState%3Didx%3D|swItem%3DMTX_d32e012fd5f14f1fb3e3859897|itemLocale%3D|mode%3D|action%3DdriverDocument&javax.portlet.tpst=bd9b6997fbc7fc515f4cf4626f5c8d01&ac.admitted=1393496865122.876444892.492883150>

TIA

Cheers. Bye.
