2.2 Heat Dissipation
The heat dissipation values for the Ethernet board and data server board
are listed in the table below. For the heating values of the system unit
of the CNC or other option units, refer to the connection manual
supplied with the CNC.

NOTE
1 Some data server boards for indicator-separated
control units (Series16i/18i-A) have the RISC option
implemented on a printed circuit board. The
dissipation values shown above do not include that
for the RISC option. For details of the RISC option,
refer to the connection manual supplied with the
CNC.
2 The dissipation value of the ATA flash card may vary,
depending on whether a large-capacity card is used
or whether the card specification has been modified.
