Memory Card LEDs
The I3H-4FXM-MEM and I3H-6 TX-MEM IOMs provide a memory card slot where a small,
separately-purchased memory card (I3H-MEM) may be inserted. Use the memory card LEDs,
shown in Figure 3-3 and described in Table 3-5, to determine the activity and power states before
removing an installed memory card.
