Figure 25: Removing the ISA Cover
Note: The MIB-OWS is a two-tiered board that plugs into one ISA
slot and hangs over into the remaining space. Remove the two metal
tabs on the Fire-Net NCM so the MIB-OWS fits.
3. Twist out the two metal tabs that cover the ISA slot and other
empty slot (Figure 26) if not already removed.
