Optical Fiber interface
SICOM3024SM offers 1 to 24 pairs of redundant 100Base-FX full duplex single mode or
multi-mode optical fiber interface, with SC, FC and ST connector. Optical fiber interface
should be used in pairs (TX and RX are a pair). TX interface is the transmitting end
connected to the receiving end RX of the optical fiber interface of another remote switch;
RX is the receiving end connected to the transmitting end TX of the same optical fiber
interface of the same remote switch. Eight pairs of redundant 100Base-FX optical fiber
interface can be used to form an optical fiber redundant ring network. In the event of the
system fault, the recovery time of the redundant ring network is less than 50ms,
effectively increasing the reliability of network operation.
RJ45 interface
SICOM3024SM offers 1 to 24 10Base-T/100Base-TX RJ45 Ethernet ports. Each RJ45
port has self-adaptation function, support MDI/MDI-X auto-connection and can be
connected to end equipments, servers, hubs or other switches in straight-through or
cross-over way. Each port supports IEEE802.3x self-adaptation, so the most suitable
transmission mode (half duplex or full duplex) and data rate (10 Mbps or 100Mbps) can
be automatically selected (the connected equipment should also support this
characteristic). If the equipment connected to these port does not support self-adaptation,
the ports will be able to send at proper speed but transmission mode is defaulted as half
duplex.
POE Interface
SICOM3024SM has 1 to 24 RJ45 ports of 10Base-T/100Base-TX with POE function.
Each RJ45 port supports feeding output of DC24V and DC48V and provides maximum
current of 600mA to remote Ethernet devices or industrial Ethernet switch at the power
receiving end. The maximum power consumption of port is configured to 5W, 10W and
15W through the network management. Each RJ45 port supports self-adaptive function
and MDI/MDI-X auto-connection.
LED Indicators
The indicators on the front panel of SICOM3024SM can show system operation and port
status, helping detect and eliminate faults. Table 3-1 describes the meanings of all
indication lights on the front panel.
