APC Network Power Management Controller

Controls rebooting of APC network PDU switches with 'telnet' network interface. Tested with the AP7900, but likely works with other models.

This handles locking of the device so that parallel calls will block, since APC has a single telnet session.

Requirements

• Python 2.x or Python 3.x
• Python Expect (pexpect) library. To install: 'pip install pexpect'
• APC with telnet network interface (tested on AP7900)

Installation

$ pip install git+https://github.com/scls19fr/APC

or

Download source and run

$ python setup.py install

The APC needs to be set up with telnet enabled, and using a fixed IP address. If a DHCP address is used, it may change, and you will have trouble connecting.
