Ethernet switch, 24 Ethernet ports on the front in RJ45 format, automatic detection of 10, 100 or 1000 Mbps
data transmission rate, coupling of network segments with different transmission speeds, auto crossing function,
installs in 19-in. (482 mm) rack
Product Description
Ethernet interface
The FL SWITCH 1924 has 24 Ethernet ports in RJ45 format. It is mounted in a 19-in. (482 mm) rack with AC power. The data transmission speed is
10 Mbps, 100 Mbps or 1000 Mbps. The switch also supports jumbo frames.
Each port has an auto crossing function. It is not necessary to make a distinction between 1:1 or crossover Ethernet cables. Mounting brackets and
power cords for EEC (CEE 7/4) and North America (NEMA 5-15) are included. User supplies screws for bracket to rack connection.
Switching properties of FL SWITCH 1924
–Store-and-forward:
All data telegrams that are received by the switch have their validity checked. Invalid or faulty data packets (>9216 bytes or CRC errors) and fragments
(<64 bytes) are rejected. Valid data telegrams are forwarded by the switch. The switch always forwards the data using the data transmission speed that
is used in the destination network segment.
–Multi-address function:
The switch independently learns the addresses for termination devices, which are connected via a port, by evaluating the source addresses in the data
telegrams. Only packets with unknown addresses, with a source address of this port or with a multicast/broadcast address in the destination address
field are forwarded via the corresponding port. The switch can store up to 8192 MAC addresses in its address table.
–Quality of service (QoS): IEEE 802.1P/Q
The FL SWITCH 1924 switches are capable of reading Ethernet packets that have already been assigned a priority level by a managed switch. In case
of heavy traffic, packets with a priority level between 4 and 7 are considered high priority and processed before packets with a priority level between 0
and 3 (2:1 ratio). After prioritization the packets are forwarded without modification.
–Grounding
The metal RJ45 socket housings are connected to earth/ground. For maximum noise immunity, shielded RJ45 connectors and cables should be used.
