Appendix C: Optional BootPROM Chip and DIP Switch Settings
202
DIP Switch Settings
Some older models of the AT-2450FTX, AT-2700FTX, and AT-2745FX
Series cards have a DIP switch you need to set if you install the optional
BootPROM chip. If your network adapter card has the switch, you must set
it to reflect the active port or speed of the adapter. The possible settings
are given in the following tables.
Note
If the optional BootPROM chip is NOT installed, the DIP switch
should be set to the factory default setting.
