ECOM ES24F2G the Gigabit Ethernet Switch User’s Manual V1.0

• Do not place heavy objects on top of the switch.

• The location must preferably be free from excessive dust, away from heat vent, hot-air exhaust

and direct sunlight.

• The switch should not be placed near large electric motors or other strong electromagnetic

sources. As a reference, the strength of the electromagnetic field on site should not exceed the
(RFC) standards for IEC 801-3, Level 2(3V/M) field strength.

• The air temperature in the location should be within a range of 32 to 122 °F (0 to 55°C).

• The relative humidity in the location should not exceed 95% non-condensing humidity.

• The distance between the RJ-45 port and the standard network interface should not exceed 100

meters.

• Adequate space should be allowed in front of all the ports, so that each port is easily accessible

for cable connections.








Cabling Guide

For 100BASE-TX and 1000Base-T ports


The 24 10/100Mbps and 2 Gigabit station ports require Cat. 5 twisted-pair UTP/STP cable for
connection. When configuring within the 10/100BASE-TX cabling architecture, the cable distance
should be within 100m.

The following table summarizes the cable requirement for 10/100/1000BASE-T connection:

10BASE-T

100 ohm Category 3, 4, 5 UTP/STP cable

100BASE-TX

100 ohm Category 5 UTP/STP cable

1000Base-T

100 ohm Category 5 UTP/STP cable


Auto MDI/MDI-X function


The SNMP-FSH2402GT is equipped with Auto-MDI/MDI-X function, which allows you to use
straight-thru cable even when connecting to another switch/hub. Simply use the straight-through
cable for all types of 10/100/1000BASE-T connections, either to a PC or to a networking device
such as other hub or switch.
