Supporting 6-Gb/s data transfer speeds, the 3U, 120 (2.5-inch) DAE has the following
components:
◆ Ten fans (two separate rows of five fans each, front and mid-section), inside
◆ Up to 120 disks (six rows of twenty each), inside
◆ One system status card (SSC), front
◆ Two Link Control Cards (LCCs), rear
◆ Four power supplies supporting one type of power supply module—a dual DC output
version, rear
Note: To see an example of the interior view of a 3U, 120 (2.5-inch) DAE, go to Figure 79 on
page 100. In this illustration all of the main components except the power supplies and
the LCCs are shown.
Figure 69 shows the front view of the 3U, 120 (2.5-inch) DAE. The front shows five fan
modules or cooling modules

and a system status card (SSC) with three status LEDs (an
enclosure fault led, an enclosure power led, and an SSC fault led).

Fan module (cooling module)
Five of the ten fan modules (cooling modules) of the 3U, 120 (2.5-inch) DAE are located
(Figure 69) on the front. Cooling is provided by these front fan modules and the five fan
modules located in the mid-section of the DAE (Figure 81 on page 103). All of the fan
modules are installed or removed with the DAE pulled out of the cabinet (for information
about how to install or remove the fan module, go to “Access to disk drives and fan
modules (cooling modules)” on page 102). For a closer look of a fan module, go to “Fan
module (cooling module)” on page 105.
14. The 3U, 120 (2.5-inch) DAE has a total of ten fan modules or cooling module (five in the front and
five in the mid-section of the DAE).
