As the 9466-ET Ethernet switch supports Auto MDI/MDI-X, a straight connected RJ45 Cat5e cable
is used to connect to any device.
It is recommended that Cat5e cables for Hazardous Area Zone 1 use are ‘Blue’ in colour and are
of good quality (see accessories section), the Safe Area cables being a colour other than blue to
aid identification.
