This PoE+ switch features up to 8 PSE (Power Sourcing Equipment) ports with plug-and-play functionality, providing power to all connected Powered Devices (PD) immediately upon connection. Fiber ports offer noise-free gigabit Ethernet transmission, enabling fast and reliable long-distance connections to other switches or control centers.The RJ45 console port allows outbound network troubleshooting in case of network issues. The USB port is used for saving configuration files, system log files, and firmware upgrades, reducing network downtime and operational costs. The switch provides various built-in traffic optimization and network performance features to prioritize industrial applications, prevent data loss during communication, and ensure stable transmission.The switch includes a topology map supporting third-party devices for network monitoring. The device complies with cybersecurity standards to protect against network vulnerabilities and safeguard assets.Constructed with industrial-grade components and housed in a high thermal conductivity IP30 aluminum case, it protects the device from tools and hazards. The wide input voltage range (24V–57V) allows operation in many marine applications without additional power outlets. For reliability, redundant power and alarm relay contacts on the terminal block ensure continuous operation and alert in case of power failure. Designed to withstand vibration, shock, drop, and temperature range of -40°C to 75°C (-40°F to 167°F), it is suitable for harsh environments.FunctionsHigh power budget for PoE devices: Compliant with PoE+ (IEEE 802.3at), each PoE port supplies 30W, with a total power budget of 240W, enabling easy 'plug-and-play' PoE for various high-power PoE devices. Advanced and smart PoE+ features save time for all users by automatic control configuration for PDs.Port-based and IEEE 802.1Q VLAN: GARP and GVRP protocols for dividing large networks into smaller segments and creating separate broadcast domains.Safety and high performance for industrial marine applications: Tested and certified for safe use under demanding conditions required by industrial and marine applications, resistant to EMI, ESD, power surge, overvoltage, overcurrent, and reverse polarity. Includes: Shock (IEC 60068-2-27), Free Fall (IEC 60068-2-32), Vibration (IEC 60068-2-6), DNV-CS-0339:2016, DNV-RU-SHIP-Pt4Ch9:2018, IEC-60945, IACS E10 (Rev.6 2014), LR certification environment categories ENV1, ENV2, ENV3.Time-efficient installation: Auto-MDI/MDIX on all ports enables automatic communication when the switch is connected.Redundant power system: Designed to connect to two power supplies and alarms simultaneously via standard industrial terminal block. If one power supply fails, the switch draws power from the alternative supply and triggers an alarm to notify technicians.SpecificationsStandards: IEEE 802.3 (10BASE-T), IEEE 802.3u (100BASE-TX), IEEE 802.3ab (1000BASE-T), IEEE 802.3z (1000BASE-SX/LX), IEEE 802.3 (Nway Auto-negotiation), IEEE 802.3x (Flow Control), IEEE 802.3ad (Link Aggregation), IEEE 802.3af (Power over Ethernet), IEEE 802.3at (Power over Ethernet Plus), IEEE 802.3az (Energy Efficient Ethernet), IEEE 802.1AB (LLDP), IEEE 802.1ad (QinQ), IEEE 802.1D (STP), IEEE 802.1w (RSTP), IEEE 802.1s (MSTP), IEEE 802.1p (Class of Service), IEEE 802.1Q (VLAN Tagging), IEEE 802.1X (Port Authentication), IEEE 1588v2 (PTP)Interface:Ports: 8 x 10/100/1000BASE-T (PoE RJ45), 4 x GbE SFP Slots, 1 x RJ45 Console Port, 1 x USB PortDIP Switch: Primary/Redundant Power Voltage Drop Alarm settingLED Panel: PWR, RPS, ALM, POST, PoE, 1000, LNK/ACTPower:Input Voltage: Primary inputs: 24~57VDC, Redundant inputs: 24~57VDCConnection: Terminal BlockPower Consumption: System: 18W, PoE Power Budget: 124W@24VDC or 240W@48VDCAlarm Relay: One relay output, 1 A @ 24V DCMechanical and Environment:Housing: Aluminum (IP30 Protection)Mounting: DIN-RailOperating Temperature: -40°C~75°C (-40°F~167°F)Storage Temperature: -40°C~85°C (-40°F~185°F)Operating Humidity: 5 to 95% RH (non-condensing)Storage Humidity: 5 to 95% RH (non-condensing)Weight: 955 g (2.1 lb)Dimension (WxHxD): 50 x 161.5 x 119.9 mm (1.97 x 6.35 x 4.72 in)Ordering InformationModelDescriptionSEN-9648PM-24VManaged 8 x 10/100/1000 PoE+ & 4 x GbE SFP Switch with USB Support, DNV MARINE APPROVALDNV compliantRedundant PowerPoE SchedulingPoE+IP Code 30DIN Rail30W per port-40°C-75°C operating temperatureUSB supportTechnical Specifications / Features8 x 10/100/1000 PoE+ ports (30W/port, total 240W)4 x GbE SFP uplink ports1 x RJ45 console port, 1 x USB portWide input voltage: 24–57VDCRedundant power and alarm relayOperating temperature: -40°C to 75°CIP30 aluminum housingDIN-rail mountingWeight: 955gDimensions: 50 x 161.5 x 119.9 mmCompliant with DNV GL, IEC, LR, IACS E10, and other marine/industrial standards
