|
|
|
This document describes the planned installation of #acr("EET") measurement systems on Maerospace equipement.
|
|
The goal of theis initial installation is to evaluate the potential of using power consumption measurement to protect Maerospace equipement.
|
|
The protection capabilities may not be limited to cyber-attacks and may also include malfunctions or unforeseen behavior.
|
|
The type of equipement is also not limited to processing servers and may include gateway computers.
|
|
|
|
= Measurement Equipement
|
|
|
|
The measurement equipement (thereafter refered to as the #acr("EET") box or simply the box) comprises a Hall Effect sensor, a digitizer, and a #acr("SBC").
|
|
The box is powered through #acr("PoE") and thus uses the same Ethernet cable for power and communication.

= Planned Installation
|
|
|
|
The initial installation will deploy 6 boxes to measure DC power at different point in the system.
|
|
Because the goal is to remain minimaly invasive, only the exposed DC cables will be monitored.
|
|
The measurement points are:
|
|
|
|
+ 2 DC cable pairs from the power supply on the right (marked 1 on @fig:rack).
|
|
+ 3 DC cables from the power supply on the left (marked 2 on @fig:rack).
|
|
+ The gateway computer outside on the rack (not marked on @fig:rack).

|
|
|
|
The following equipement will be added to the system:
|
|
|
|
- 5 EET measurement boxes.
|
|
- 5 replacement cables for the cables that are monitored.
|
|
- 1 PoE switch.
