Verifying Operation

Elements begin operating when power is applied. Check the enclosure status LEDs in the
front, lower right corner (see Figure 2–3). If the display is not exactly as shown, there is an
element error condition. Check the drive and enclosure status LEDs on the front and the
EMU, power supplies, blowers, and I/O module status LEDs on the rear (see Figure 2–4)
to determine the defective element.
NOTE: Either of drive displays in Figure 2–3 indicate a properly functioning disk.
