*Short pins in mating backpanel connector.

[1]This pin may be connected to external logic to detect the presence of the drive. The drive connects this pin to the common ground.

[2]Pins 9, 10, 17, 18, and 39 are option select pins and are tied high by the drive circuitry. The preferred elec- trical connection at the backplane is either open or grounded (open for the ‘1’ setting, grounded for the ‘0’ setting). Alternatively, these pins may be driven by a 3.3V logic device, pulled up to 3.3V through a pull-up resistor (recommended size of 10k ohm), or grounded through some other means.

9.5.5FC-AL transmitters and receivers

A typical FC-AL differential copper transmitter and receiver pair is shown in Figure 17. The receiver is required to provide the AC coupling to eliminate ground shift noise.
