IND331 Harsh

To open the harsh enclosure, use a flat blade screwdriver. Push the blade into each of the two slots
in the cover (indicated in Figure 2-4) to compress the spring clip until the cover pops up. When
both corners are free, press the cover upward until it clears the front edge of the housing. Then,
press it backward until it unlatches the two remaining spring clips. Lift it carefully off the enclosure
and swing it forward. The cover is attached to the enclosure by two strain relief/grounding cables,
and is connected to the main board by the video/keyboard harness (see Figure 2-21).
