Long-term switch FAQ

Q: What long-term agreement with the switch? Can affect other network equipment connected?
A: The long-term switch using TCP / IP protocol, using an extension of the agreement mechanism, the network latency within the framework of the standard does not affect other network equipment

Q: ES1200 Series and ES4000 series What is the difference?
Answer: ES1200 series with an external power supply, suitable for indoor environment, cost-effective use of built-in power ES4000 family, stability, reliability, high

Q: Why I bought a long-term switch not reach the nominal distance?
A: Make sure to use a standard unshielded twisted-pair UTP cable or higher.

Q: how to determine network cable is the standard five or more lanes in unshielded twisted-pair?
A: 1, the proposed use of well-known brands of cable
2, if conditions permit, available multimeter measured cable resistance, the standard 300 meters of non-shielded five lines about 30 ohms DC resistance of about

Q: ES3200 Series and ES3300 series What is the difference?
Answer: ES3200 series is 10M, transmission distance up to 1,200 meters, ES3200 series is 100M, transmission distance up to 300 meters, are used HyperTrans technologies requires the pairs.

Q: The use of long-term switch uplink port, is that you can also use the nearest port of their neighboring
Answer: Uplink port is a common form of switch port, which is between the two switches in order to facilitate the cascading port. It is adjacent to its normal port and use the same channel, and therefore, if you use the Uplink port, and the other with the adjacent normal port no longer use. The two-port is called to share the port can not be used simultaneously.

Q: I have been using five types of shielded cable, it did not want to re-wiring how to do?
A: 1, so that five shielded cable grounded at both ends.
         2, can be used to support long-term switch over longer distances, for example, the use of five ES3202 shielded cable of up to 500 meters transmission distance

Q: ACORID ES series switches have lightning protection measures for long-term
Answer: ACORID ES switches full range of long-term use of two lightning: Anti-static pressure and the use of three pole ceramic discharge and transient voltage suppressor TVS for ESD protection, (TVS is a form of high-performance diode protection device. When the TVS diodes are reverse-polarized transient high-energy shocks, it can in order to the order of 10-12 seconds, the speed of its high-impedance between the two poles into a low-impedance, absorbing up to several kilowatts of power surges, so that between two poles The voltage clamp at a predetermined value, the effective protection of electronic circuits of the precision components, from a variety of surge pulse damage.)
