    Instruction manual for the SECO-LARM ENFORCER NS-104UT-MAQ and NS-508UT-GAQ Unmanaged PoE Switches — fast packet-forwarding Ethernet switches designed for delivering data and power to IP cameras, access control devices, and other PoE equipment.

    Introduction

    ENFORCER Unmanaged PoE Switches provide Ethernet and power to PoE devices such as IP cameras, IP access control, IP speakers/intercoms, and IP telephony equipment. Fast packet forwarding and extra backplane bandwidth ensure clear images at fast transmission speeds, making them well-suited for HD CCTV installations.

    Model Comparison

    Model Ethernet Ports Bandwidth VLAN Power
    NS-104UT-MAQ 10/100Base-TX 4 Downlink, 2 Uplink 1.2Gbps Yes 60W Adapter
    NS-508UT-GAQ 10/100/1000Base-TX 8 Downlink, 2 Uplink 20Gbps No 120W Built-in

    Features

    • Provides Ethernet data and power to multiple PoE devices (IP cameras, access control, speakers/intercoms, VOIP, etc.)
    • Fast packet forwarding for clear images and smooth video transmission
    • Easy plug-and-play installation
    • Supports 10/100BaseT (NS-508UT-GAQ also supports Gigabit 1000BaseT)
    • Conforms to IEEE 802.3, 802.3u, 802.3af, 802.3at (NS-508UT-GAQ also 802.3ab); IEEE 802.3x flow control

    Parts List

    • 1x PoE Switch
    • 1x Power adapter (NS-104UT-MAQ only)
    • 1x AC Power cord
    • 1x Manual

    Sample Installation

    1. Determine the best location for the switch — the uplink cable (and PoE device cable, except NS-104UT-MAQ with VLAN turned ON) cannot exceed 328ft (100m).
    2. If installing the NS-104UT-MAQ, make sure the VLAN function switch is set correctly.
    3. Turn off power to both the display device and the PoE device before proceeding — installation under power can damage the transmission equipment.
    4. Connect the PoE device(s) to a downlink port using a Cat5e/6 cable (EIA/TIA 568A or 568B).
    5. Connect the DVR or computer to the uplink port using a Cat5e/6 cable (same standard on both ends).
    6. Connect power to the switch and confirm the power LED and PoE LED (on connected ports) are on.
    7. Turn on the display device and verify the system is functioning properly.

    Troubleshooting

    Symptom Checks
    PoE device doesn't function correctly Confirm both input and output devices are on; ensure Ethernet cable doesn't exceed 328ft (100m) or 656ft (200m) for NS-104UT-MAQ with VLAN on; confirm no PoE device exceeds 30W; confirm cable meets EIA/TIA 568A/568B and both ends match (not a crossover cable); test the cable and try a known-good PoE device.

    FCC Compliance

    This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that it may not cause harmful interference and must accept any interference received. Unauthorized changes or modifications could void the user's authority to operate the equipment. No change to the antenna or device is permitted without voiding RF exposure compliance.
