3 HARDWARE 3.2 WIRING
For the 9G/9H CPU, the 10Base-T port can only be used when the CH1 10Base-F fiber has been removed. The
10Base-T Ethernet cable and the CH1 10Base-F fiber cable cannot both be installed at the same time.
NOTE
For 9J/9K CPU, the 10/100Base-T port has the lowest priority and is only active if both CH1 and CH2 fiber links are
down. Installation of the 10/100Base-T Ethernet cable at the same time as the CH1 and/or CH2 100Base-F fiber
cables does not affect the communication over the CH1 or CH2 fiber ports.
