M12 Ethernet Connections
Use data-quality (not voice-quality) twisted pair cable rated category 5e (or better) with standard M12
(D-coded, male, 4-pin) connectors. Straight-through or crossover Ethernet cable can be used for all devices
to which the switch is connected because all the ports are capable of auto-MDI/MDIX crossover detection.
e maximum cable length for 10/100/1000BaseT is 100m [328ft].

NOTE: The supplied M12 caps need to be used on open (disconnected) ports. Replacement caps
(Part # ZP-JBH-CAP) are available from AutomationDirect.com.
Ethernet Fiber Wiring Guidelines
Some switches include ber ports, either SC or ST connector, or an SFP option. Refer to the switch
specications for details on the available connection types.
For each ber port there is a transmit (TX) and receive (RX) signal. When making your ber optic
connections, make sure that the transmit (TX) port of the switch connects to the receive (RX) port of
the other device, and the receive (RX) port of the switch connects to the transmit (TX) port of the other
device. Use standard ber optic wiring techniques (not covered by this manual) to make your connections.

It is important to consider the output power and the receiver sensitivity for each end of each ber
connection, especially when the distances that each ber transceiver in each switch are specied to
support dier or when the transceivers (switches) are separated at a distance dierent than that which the
transceivers are specied to support.
SC and ST Fiber Connections
e SC and ST type ber ports work in multi-mode at 1310nm wavelength, and are compatible with
50/125 or 62.5/125 µm ber. When connecting the ber port to another device, please follow the
guidelines in the previous subsection.
