BМТ401 LAN switch

BMT401 LAN switch is designed to connect several subscribers or local network nodes with the ability to power subscribers using PoE technology.

BМТ401 is intended for operation under the influence of the following external factors:
  • ambient temperature from minus 40°С to plus 50°С;
  • relative air humidity up to 100% at a temperature of plus 35°С;
  • atmospheric pressure from 60 to 107 kPa. 
  • BМТ401 has 12 ports supporting the following standards:
    – IEEE 802.3i (10Base-T);
    – IEEE 802.3u (100Base-T);
    – IEEE 802.3ab (1000Base-T);
    – IEEE 802.3at РоЕ (hereinafter - PoE) 
  • each port provides power supply (PoE) to the connected device with a power consumption of up to 25 W; 
  • process connector RS is intended for diagnostics and adjustment of the product by the representative of the manufacturer; 
  • power supply is carried out from a DC network with a voltage of 16 to 32 V; 
  • power consumed by BМТ401 does not exceed 300 W; 
  • overall dimensions - 243x190x75 mm; 
  • product weight - 2.1 kg; 
VMT401 remains operational:
  • after exposure to the extreme low ambient temperature minus 50°С; 
  • after exposure to a maximum elevated ambient temperature of 60°C; 
  • during and after exposure to a reduced relative humidity of 20% at a temperature of 30°C; 
  • after exposure to the limiting reduced atmospheric pressure of 25 kPa; 
  • during and after exposure to sinusoidal vibration with vibration acceleration amplitude of 5 g in the frequency range from 5 to 500 Hz; 
  • after exposure to linear acceleration with an amplitude of vibration acceleration 6 g in any direction;
  • after exposure to a single mechanical shock with a peak shock acceleration of 100 g and a duration of shock acceleration from 1 to 5 ms;
  • during and after exposure to repeated mechanical shock with a peak shock acceleration of 15 g and the duration of the shock acceleration impulse from 5 to 15 ms; 
  • during and after exposure to static dust (sand) with a concentration of (5 ± 2) g/m 3 at a circulation speed of up to 1 m/s; 
  • during and after the impact of rolling with an amplitude of up to ± 45° with a period of 7 to 16 s; 
  • during and after exposure to prolonged (without time and angle limitation) inclinations; 
  • after exposure to acoustic noise with a sound pressure level of 130 dB in the frequency range from 50 to 10000 Hz for 20 s; 
  • after exposure to atmospheric precipitation (rain) with an intensity of (5 ± 2) mm/min; 
  • after exposure to atmospheric condensed precipitation (frost and dew); 
  • after exposure to salt (sea) fog; 
  • after exposure to biological factors (bio-pests and rodents, after exposure to molds).
