1. Intellislot 1 port shares communication resource with the RS232 port. To avoid conflict, when the RS232 port is used
for service or commissioning, it is not recommended to use Intellislot 1 port.
2. Intellislot 2 port shares communication resource with the SPM monitoring module. If the SPM monitoring module is
configured, optional communication cards cannot be installed in Intellislot 2 port.
