During our maintenance activities, we had faced several times the necessity to connect the console port connections on \ac{ACA} correlator hardware modules. How we did this at the beginning was to personally travel to \ac{AOS} and connect the desired module using the laptop provided by \ac{NAOJ} (National Astronomical Observatory of Japan) with the provision to have this laptop connected to the network for remote access. The shortcomings of this approach are that we can connect only one module at a time, and if we need to manage another module, we would be forced to have someone to perform the change at the \ac{ACA} Correlator room manually. This with the time penalties of personnel availability and work time constraints (engineers from Japan work when local staff is not on duty due to the extensive time zone differences between Chile and Japan).
The solution presented was based on a server that allows us to establish a remote connection to a device which manages all serial connections on a particular quadrant simultaneously. More specifically, ssh sessions are provided which enable direct connection to a desired serial port. For accomplishing this mission, I completed a series of milestones: prepared a formal document with system engineers for approval by the \ac{ALMA} stakeholders; established cable standards (Ethernet/RS-232), and technical specifications for each quadrant; assisted the construction process and installation preparation; placed and configured terminal servers; arranged network addresses for general access; tested \ac{PDU} inputs for power control of the terminal servers; added switch access support from each quadrant; and documented usage instructions for engineers, technicians, and managers.
