4U Chassi 17 slots, for E1-SERIAL converters

19-Inch 4U rack 17 slots for E1 to serial converter cards


Catégorie :

Product Description

 This is 4U 17 interfaces Rack. The rack height is 4U, can insert 17 block interface conversion cards, or1 block network management card and 16 feature cards, each card works independently. Different interface conversion cards can be inserted in and work simultaneously on the same rack. It uses communication isolation technology communication to separate system power from interface conversion card completely to ensure the reliability of the entire system.


Ø  Can insert various types of interface converter produced by our company

Ø  19-Inch 4U standard rack, using the principle of air, good rack radiating performance, ease of management and maintenance

Ø  Can insert up to 17 hot-plug cards, each interface conversion card can achieve conversion function independently

Ø  Two power panel slots support mutual hot spare between two power units. Each power unit can support the entire rack work full of configuration.  Two power units work together through shunt on the one hand to reduce each power unit load, on the other hand by mutual hot spare to ensure if one power unit having problem within the time rack inner function panel can work

Ø  Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV, Impedance (2 Ohm), CM(Common Mode): 6KV, Impedance (2 Ohm) standard

Ø  Fully meet Telecom operation requirements, Mean time Between Failures (MTBF) is more than 50,000 hours.
