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 Requirements
Ether-FSH2400N
Fast Ethernet Switch is primarily designed as a central switching device to
provide 10/100Mbps bandwidth to your Ethernet/Fast Ethernet LAN.
Cable requirement for 100BASE-TX Port
Those 24 RJ-45 station ports (MDI-X) all 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 10/100BASE-TX connection:
10BASE-T
100 ohm Category 3, 4, 5 UTP/STP cable
100BASE-TX
100 ohm Category 5 UTP/STP cable
Straight-through cabling
Under most conditions, the 24 station ports on the Switch accept normal, straight-through cables, i.e.,
standard UTP/STP cables, which are the only ones that can be used with a RJ-45 connector
interface.
Normally, 10BASE-T networks require a straight-through Cat. 3, 4, 5 UTP/STP cabling system.
The cabling system could be found in most existing Ethernet network installations.
100/100BASE-TX networks require Cat. 5 UTP/STP cabling system. The pin assignments for a
straight-through cable are shown in Figure 3-5 and 3-6.
