Presence detectable baffle for electrical components in a computing system

1. A method of directing air flow in a computing system, the computing system including a slot for receiving an electrical component having a set of pins, the method comprising:

passing signaling information through a presence detectable baffle that has been inserted into the slot, wherein the presence detectable baffle includes a passive chassis having a form factor consistent with an electrical component and a presence detectable pin set that is consistent with the electrical component; and

causing, by the presence detectable baffle, air flow to be directed through the computing system in a manner consistent with air flow through the computing system when the electrical component is inserted in the slot wherein:

the presence detectable pin set is configured to indicate to a system manager that the presence detectable baffle is installed and that the presence detectable baffle is passive; and

the system manager is configured to identify, the presence detectable baffle after installation of the presence detectable and manage computing system operating attributes in dependence upon presence detectable baffle attributes.

2. The method of claim 1 wherein the presence detectable baffle includes a pin set compatible with the peripheral component interconnect express (‘PCIe’) specification.

3. The method of claim 1 wherein the slot is a peripheral component interconnect express (‘PCIe’) expansion slot.

4. The method of claim 1 wherein the electrical component of the computing system is an expansion card.

5. The method of claim 1 wherein the electrical component of the computing system is a memory module.

6. The method of claim 1 wherein passing signaling information through the presence detectable baffle includes passing a predetermined voltage value over predetermined pins of the presence detectable pin set.
