Complete installation and power on debugging process
2.1 Step by step installation operation
Unpacking inspection: check the standard configuration (switch, power terminal, manual+CD), and inspect for transportation damage;
SFP module pre installation (only for ZZZ6 model): Remove the slot protection cap, close the latch and push the SFP module into the buckle lock, only allowing the use of Husman original SFP;
IP address marking: Fill in the device IP in the body label area for easy on-site operation and maintenance identification;
Power and alarm terminal wiring
Dual DC redundant power supply, equipment automatically selects the higher voltage channel; Single power supply will trigger the FAULT alarm, which can be blocked on the network management interface;
FAULT relay monitoring failure: power loss, port link disconnection, redundant failure of ring network, complete machine self-test failure, ring network configuration error; Support manual control of relay output external devices through web pages; Explosion proof scenarios must strictly adhere to physical parameter limitations;
DIN rail installation and grounding
Compatible with 35mm standard DIN EN 60175 rail, snap on quick fix; Connect the grounding screw to protect the grounding wire; Grounding of twisted pair shielding layer to panel;
Insert the terminal into the body and connect it to the power supply to automatically turn on the device;
Data cable connection
RJ45 electrical port: Cat5e cable can transmit up to 100m and supports MDI-X automatic line sequence;
DSC fixed fiber: multimode 50/125 μ m up to 5km, 62.5/125 μ m up to 4km; single-mode 9/125 μ m up to 30km; must be docked with the same type of fiber;
