[1] The drive has a 2.2K ohm resistor in series with this LED driver. Tie the minus side of an
external high-efficiency LED (i.e., 2ma) to this pin. Connect the plus side of the LED to
+5V.
[2] An external current-limiting resistor is required when connecting an LED to this pin. The
minus side of the resistor/LED combination is connected to this pin. Connect the plus side
to +5V.
[3] Jumper storage location (across pins 2 and 4).

8.2.1 J6 connector requirements
Recommended mating connector part number: Berg receptacle, 6-position, Berg part number 690-006.
8.3 Drive orientation
The drive may be mounted in any orientation. All drive performance characterizations, however, have been
done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two pre-
ferred mounting orientations.
8.4 Cooling
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding
the drive will not exceed temperature conditions specified in Section 6.4.1, "Temperature."
The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and
head and disc assembly (HDA). You should confirm that adequate heat removal is provided using the tempera-
ture measurement guidelines described in Section 6.4.1.
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1,
in which case the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is
