The AP9605 PowerNet SNMP Card is a SmartSlot card for APC SmartUPSs. It allows full management and monitoring via SNMP (and its Telnet interface). They are considered *old* cards, but work perfectly, and are cheap - usually around $20 refurbed.
From my blog: In the theme of upgrades, I also purchased two APC SmartUPS1000 units from refurbUPS.com. Now, I know that a lot of people are perfectly happy with serial connectivity. And it has its positives. But I'm running 2-3 servers per UPS, older servers, wanted to be able to monitor the UPSs, and perhaps control server shutdown, over the network.. So, I found that refurbUPS.com also sells SNMP management cards for them. They sell a refurbished AP9605 - it's an old 10BaseT PowerNet SNMP-only card (with telnet management). Seemed good, and the price of $15 was right.
They showed up, but I couldn't find much about them online, let alone anything useful.
After a phone call to APC, I managed to get the user's manual emailed to me. The few instructions I found online were totally wrong.
The general setup goes like this: 1) Connect network cable to card 2) Connect serial cable between a computer and the UPS's serial port. 3) Get a terminal emulator, like kermit. Settings for kermit: set modem-type none set carrier-watch off set speed 2400 4) connect and press enter. You'll be asked for a username and password. Use "apc" for both. 5) Setup the network - IP, mask, gateway, etc. 6) Ready-to-go!
Update 2008-07-23: I've only used these devices with APC serial cables. As per a reader who was kind enough to drop me an email. connecting with a non-APC-pinout (standard or null modem) cable can crash the machine used to connect. Please be warned. Pinouts are available on the Network UPS Tools site.
