is CX22E4GF VER.A, and the silkscreen of the E4GFA is CX22E4GFA VER.A. The card
labels show the card types. The label of the E4GF is CX22E4GF, and the label of the E4GFA
is CX22E4GFA.
l The card appearances are different. The E4GF has the cooling fins, as shown in Figure
4-3, whereas the E4GFA does not, as shown in Figure 4-4.
Table 4-11 describes the meanings of indicators on the E4GF.
