Communication upgrade module for communication with an information handling system air mover
A communication module may be used in an information handling system comprising an air mover configured to drive a flow of air and a processing component communicatively coupled to the air mover for controlling operation of the air mover via a first wire configured to communicate air mover speed commands from the processing component to the air mover for controlling a speed of the air mover and a second wire configured to communicate tachometer information from the air mover to the processing component. The communication module may include a connector other than an air mover connector configured to couple the air mover to the first and second wire and logic configured to monitor for an escape sequence communicated via first wire from the processing component to enter a command mode and responsive to detecting the escape sequence, communicating information regarding the air mover to the processing component via second wire.

responsive to receiving the command, communicate information to the processing component via the second wire.
5. The information handling system of claim 3 , wherein the removable communication module is further configured to, during the command mode:
monitor for a command from the processing component via at least one of the first wire and the second wire;
determine whether the command is a command for exiting the command mode; and
responsive to receiving the command for exiting the command mode, exit the command mode.
6. The information handling system of claim 1 , wherein the connector is mechanically coupled to the air mover.
7. The information handling system of claim 1 , wherein the connector is configured such that the air mover connector is coupled between the processing component and the connector.
8. A method comprising, in an information handling system comprising an air mover configured to drive a flow of air and a processing component communicatively coupled to the air mover for controlling operation of the air mover via a first wire configured to communicate air mover speed commands from the processing component to the air mover for controlling a speed of the air mover and a second wire configured to communicate tachometer information from the air mover to the processing component:
monitoring, with a removable communication module coupled to the first wire and the second wire via a connector other than an air mover connector configured to couple the air mover to the first wire and the second wire, such that the air mover remains communicatively coupled to the processing component via the first wire and the second wire when the removable communication module is removed from the connector, for an escape sequence communicated over the first wire from the processing component to enter a command mode; and
responsive to detecting the escape sequence, communicating information regarding the air mover from the removable communication module to the processing component via the second wire.
9. The method of claim 8 , further comprising, responsive to detecting the escape sequence, receiving information at the removable communication module from the processing component via the second wire.
10. The method of claim 8 , further comprising, responsive to detecting the escape sequence, entering the command mode.
11. The method of claim 10 , further comprising, during the command mode:
monitoring at the removable communication module for a command from the processing component via at least one of the first wire and the second wire; and
responsive to receiving the command, communicating information from the removable communication module to the processing component via the second wire.
12. The method of claim 10 , further comprising, during the command mode:
monitoring at the removable communication module for a command from the processing component via at least one of the first wire and the second wire;
determining at the removable communication module whether the command is a command for exiting the command mode; and
responsive to receiving the command for exiting the command mode, exiting the command mode.
13. The method of claim 8 , wherein the connector is mechanically coupled to the air mover.
14. The method of claim 8 , wherein the connector is configured such that the air mover connector is coupled between the processing component and the connector.
15. A removable communication module for use in an information handling system comprising an air mover configured to drive a flow of air and a processing component communicatively coupled to the air mover for controlling operation of the air mover via a first wire configured to communicate air mover speed commands from the processing component to the air mover for controlling a speed of the air mover and a second wire configured to communicate tachometer information from the air mover to the processing component, the removable communication module comprising:
