This is a 16 port 2U(?) smart power strip connected to the IPKVM box in the rack downstairs. We can use it to power of and on kit in the rack and measure total power consumption of the rack.
current port assignments
- A1: the ipkvm box itself
- B1: the Dlink POE midspan thing
- B2: Asimov
- B3: Babbage
- Get borg on the pdu
- Get the hp thing on the pdu
- graph power usage
- and loads of other stuff...
We use the pdu with the ipkvm thing, so this info isn't needed, might come in handy at some point tho.
Default behaviour is to act as a fairly dumb power strip - after a few seconds, all the outputs are turned on in sequence and remain on.
The control connection is RS232 to the RJ45 'IN' connector, as described in table A.19 of the manual above. This indicates the following connections to a 9-pin PC-AT RS232 connector, assuming the signals are crossed in the same way as a chained PM20i.
|Name||RJ45 pin||direction||D9 pin||Name|
It doesn't make sense to connect the two DSR pins together. This occurs because in chaining the units, pin 8 is connected anyway by the RJ45 cable and is presumably not used.
Connecting this to a PC running Kermit at 9600 baud, I got an immediate login prompt. The unit I tried had the factory default users set - no groups or usernames, user admin has password pm8. I didn't have to set any special line conditions so it's possible a 3-wire data-only connection would do.
If you need to reset the password, see loopback plug wiring (link pins 1-8, 2-7, 3-6)
