• Non-Blocking Switching Performance
• Supports up to 9,216 bytes Jumbo Frame Packet for secured large file transmission
• 2 Relay Outputs for Gigabit port Link Failure Detection
• IEEE 802.1p Quality of Service (QoS) for packet forwarding precedence
• Auto Gigabit RJ-45/SFP module detection
• IP31 rugged aluminum case
• Dual 24V (12-48V) DC power inputs
• Operating temperature -25~70oC
