In-Depth Information
Using the multiple individual connectors shown in the previous figure, you would have to
plug each connector into the proper pin. Some internal chassis USB cables use two 5-pin
inline connectors, in which case you just need to ensure that you don't put them on back-
ward. Consult your motherboard and chassis manual for more information if you are un-
sure about your particular connections.
Caution
If your chassis uses multiple individual nonkeyed connections, you must be sure to connect
themproperlytotheconnectoronthemotherboard.Ifyouconnectthemimproperly,youcan
cause a short circuit to occur that can damage the motherboard or any USB peripherals you
plug into the front panel connectors. Higher-quality motherboards usually have self-healing
fuses on the power signals, which can prevent damage if such a situation occurs.
Although IEEE 1394 (FireWire/i.LINK) is not present on all motherboards, many mid-
range and high-end boards do incorporate this feature or offer it as an option. You can
also add FireWire via an expansion card, and many of the cards have header connectors
for front panel or rear bracket connections similar to that found on a motherboard.
