System status card
The system status card (SSC) is a removable circuit board located on the bottom, front of
the 3U, 120 (2.5-inch) DAE and provides the following functionality (Figure 69 on
page 91):
◆ Three status LEDs (Table 42)
• SSC fault LED
•Enclosure fault LED
• Enclosure power LED
◆ Fan voltage of 12 VDC is provided to two fans; fan 0 located in the front of the DAE and
fan 7 located in the mid-section of the DAE; this maintains proper cooling,
◆ An inlet temperature sensor that determines the ambient temperature outside the
enclosure
◆ SSC resume EEPROM for tracking manufacturing information
