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 10/100BASE-TX ports
The 24 RJ-45 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 10/100BASE-TX connection:
10BASE-T
100 ohm Category 3, 4, 5 UTP/STP cable
100BASE-TX
100 ohm Category 5 UTP/STP cable
Auto MDI/MDI-X function
The SNMP-FSH2400RS 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 10/100BASE-TX connections, either to a PC or to a networking device such as
other hub or switch.
