SRS2000 series rack-mount Layer-2 managed industrial switch
The SRS2000 series rack-mount Layer-2 managed industrial switch supports 4 GE/FE SFP + 24 PoE Gigabit copper, and 4 GE/FE SFP + 24 Gigabit copper, for harsh industrial environments as a cost-effective solution. Operating temperature -40°C~ +75°C.
The SRS2000 series rack-mount Layer-2 managed industrial switch uses redundant dual inputs of 100~240VDC/VAC and 48~54VDC (PoE models), rack mounting; PoE models deliver up to 30W per PoE port. Rugged aluminum alloy housing, IP40, high-level EMI/EMC tests and strict burn-in meet industry stability/durability standards.
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?
+All Gigabit ports
