    Features of product

    We cope with "PoE" of all port IEEE802.3af/at conformity feeding! 1000BASE-T-adaptive switching hub for corporations which are usable on severe condition of "50 degrees Celsius" with metal case

    It supports "PoE" of all port IEEE802.3af/at conformity feeding. 1000BASE-T-adaptive switching hub for corporations

    It is giga switching hub for 1000BASE-T-adaptive corporations which secured superior reliability, stability. It is exothermal and adds to superior metal case adoption and realizes "action environment temperature 50 degrees Celsius", and use environment comes even to severe environment of factory and various facilities which are easy to become high temperature by operation in peace for long term.

    24 port models


    The PoE function deployment that can supply power as well as data only with LAN cable

    PoE-adaptive model copes with the high output PoE feeding supporting IEEE802.3at standard (PoE+).
    Supplying power is possible with data only with LAN cable at Fixed Wireless Access point or Network camera. We contribute to reduction of large power supply construction cost.

    When PoE feeding reaches the upper limit of system, we will tell with "PoE MAX" LED.

    Example utilizing PoE

    Fanless design ideally silent for feeding to Network camera and IP telephone

    Silent fan reply design that the use in the desktop circumference is comfortable as for 5 ports which is most suitable for feeding to Network camera and IP telephone, 8 port models.

    Target model EHB-UG2B08-PL2/EHB-UG2B05-PL

    All giga Switch which are most suitable for Network which of data continues increasing year by year

    All ports which are most suitable for current duties Network that giga Network became standard are Switch for giga.

    It supports rack mounting setting corresponding to the effective accommodation of 19 inches

    3 pin -2 pin conversion adapters or mounting bracket for rack fixation of 19 inches are attached and can easily incorporate in 19 type rack mounting system.

    The loop prevention function deployment that minimizes network failure

    It is equipped with "loop prevention function" to reduce Network down and minimizes network failure by automatically blocking target port. "Loop prevention function" can change ON/OFF in Switch.

    What is Network loop? Phenomenon that packet continues spreading in network path becoming loop architecture endlessly, and Network is saturated in communication packet, and to cause obstacles such as Network down.

    Even as for the summertime becoming severe environment cheap; constant; heat resistance 50 degrees Celsius correspondence to provide possible motion

    At place that is easy to become severe environment in the summertime such as school or apartment cheap; constant; is correspondence to operating temperature 50 degrees Celsius to provide possible motion. It is available without minding setting environment.
    We clear immunity examination of "IEC61000-4" conformity. We realized high reliability and longer life appropriate for switching hub which operation was demanded from for 24 hours.

    We further guarantee by user's registration for three years of extension guarantee relief for two years (sendobakku maintenance)

    We guarantee for three years of relief for term of a guarantee (sendobakku maintenance).
    Furthermore, we do extension guarantee (five years in total) of two years only in customer who had you register within three months after purchasing.

    ※ELECOM support & service company (ESSC) performs about extension guarantee offer for two years by user's registration.

    We cope with maintenance service to support use of long-term apparatus

    bnr_support_repair We prepare for delivery maintenance (last soup stock) and sendobakku maintenance (extension) with option to be able to use apparatus in peace in the long term.
    You have a choice depending on needs of customer.

    About maintenance service, it is this in detail

    Delivery maintenance (optional service)

    We send substitute plane to designated place of customer at the time of obstacle. Please send back apparatus with malfunction to us after the exchange in customers.

    sendobakku extension maintenance (optional service)

    Extension service of standard free term of a guarantee (three years). We have you send inoperative apparatus and send repair completion article or substitute plane to customer-designated place.

    It is equipped with magnet (only as for 5 port/8 port models), abundant function including jumbo frame correspondence

    Magnet (separate sale)

    eresapo By having you attach magnet sold separately, setting to metal surface is enabled, too.
    ※Only EHB-UG2B05-PL (5 port models)/EHB-UG2B08-PL2/EHB-UG2B08-PL/EHB-UG2B08F-PL (8 port models) supports.
    ※EHB-UG2B16F-PL (16 port models), EHB-UG2B24F-PL (24 port models) are non-compliant.

    Optional magnet EHB-EX-MG4 for hub is this >>

    Jumbo frame correspondence

    Data transmission that is higher-speed between jumbo frame Supported Devices is possible in correspondence with jumbo flame.
