Raritan PX20 PDU

Similar Raritan PDUs may have similar model numbers, such as ‘PX2’. The following instructions may apply.

The firmware for these PDUs is from 2007, and does not support modern HTTPS or SSH protocols. I have figured out how to SSH into one, but not access the Web interface via HTTP (yet).

The serial console is accessed via an RJ45 port, next to the LAN and ‘feature’ ports. Raritan supply a proprietary DB9 to RJ45 cable, it’s not a Cisco console cable.

To reset a PDU, power it on. It will take up to two minutes to boot, at which time the LED display will light up and give power information. Connect the serial console at baudrate 9600. Use a paperclip or similar to press the ‘reset’ button, at the same time tapping ‘Esc’ into the console. the ‘=>’ prompt will appear. If any other prompt appears here, the process has failed, try again. Type ‘defaults’ followed by return at the ‘=>’ prompt. The PDU will reset its configuration to default values.

Once the PDU has rebooted, follow instructions on the console. I recommend typing ‘config’ to configure the network, accepting all default values.

The PDU will request a DHCP lease. Look up its address on your DHCP server.

Log in via SSH with the default credentials, 'admin’/'raritan’.

ssh -c 3des-cbc -oHostKeyAlgorithms=+ssh-rsa \
    -oKexAlgorithms=+diffie-hellman-group1-sha1  -l admin <=IP ADDRESS>

Turn power outlets off and on.

set /system1/outlet1 powerState=off

set /system1/outlet1 powerState=on

Outlets are all on by default. On Raritan PDUs, a green light next to an outlet indicates that it is off, red indicates that it is on. This is because red lights mean danger or ‘live’.
