Supports 18 slots for compact applications
Supports redundant dual power inputs
Distributed design; each fiber transceiver module has an independent power module
Fanless; operating temperature -40℃ to +75℃
The MAK-A18HH chassis is a standard 19-inch 2U industrial fiber transceiver chassis with 18 slots for independent MSM series industrial fiber transceivers; all slots are universal with no fixed position/order.
The MAK-A18HH industrial fiber transceiver chassis supports redundant dual power inputs with distributed design; each service slot is powered independently to avoid single-point failure.
The cable is connected, but the port will not come UP / the link is down. What should I check?
+What are the PoE power specifications?
+Which ring protocols are supported, and what is the self-healing time?
+How should I choose between Layer-2 and Layer-3 industrial switches?
+Can non-OEM SFP optical modules work normally?
+How do I restore factory settings if I forget the device login password?
+What are the power supply requirements for industrial switches?
+What are the operating temperature range and protection rating of industrial switches?
