Data Sheet

1Description

The FL SWITCH SFN… range of Factory Line switches with

standard functions in numerous versions can be used for

quick and cost-effective Ethernet network expansion to the

field level. Due to their narrow housing design, the

components are suitable for universal remote use in control

cabinets and junction boxes. The switches have five or eight

ports, up to two of which are glass fiber ports provided in SC

or ST format. The switches support the auto negotiation

function at the twisted pair ports and offer transmission

speeds of 10/100/1000 Mbps depending on the switch

version. Mixed operation for the connection of segments

with different data transmission speeds is also supported.

The glass fiber ports only support 100 Mbps or 1000 Mbps

(Gigabit version).

The RJ45 ports offer an auto crossing function, which means

it is not necessary to make a distinction between 1:1 and

crossover cables.

The fiber optic ports can be used to extend the segment

length up to 20 km. Unused RJ45 ports can be fitted with

security caps to provide mechanical protection against

unauthorized use.

The FL SWITCH SFN…GT… switches offer additional

gigabit performance, alarm contact and redundant power

input capability.

2Features

– Increased network performance

– Switched Ethernet reduces traffic and non

predictable timing

– Quality of Service: Pretagged high priority

messages are forwarded before lower priority

messages during periods of high network traffic

– Gigabit options for data intensive applications

– Gigabit switches support jumbo frames up to

9600 bytes per frame

– Easy network expansion

– No configuration of the switch

– Auto negotiation and autocross simplify cabling

– Coupling copper network segments with different

bit rates with automatic detection of the data

transmission speed of 10 Mbps, 100 Mbps or

1000 Mbps depending on the switch version

– Fiber optic options extend distance and electrical noise

immunity

– 1- or 2-port options

– SC or ST connector options

– Multimode or singlemode option

– Low cost, low complexity security (optional)

– Connect Layer 1 security elements at the RJ45 port

to restrict access or tampering

Please note the different connection directions of the transmission media for five-port switches: copper cables

are connected at the front, glass fiber cables at the bottom.

Make sure you always use the latest documentation.

FL SWITCH SFN… and 7 are considered high priority and processed before packets with a priority level between 0 and 3. After prioritization the packets are forwarded without modification. 8 Dimensions frames are technically defined as 9000 bytes or less, but commercial use of the term has been applied to packet sizes over 9000 bytes. Jumbo frames are used to reduce network loading when transferring large data files.
PAGE 12
FL SWITCH SFN… Bidirectional data transfer guidelines When using jumbo frames for bidirectional data transfers, the generation of pause frames starts at 3000-byte size frames. Traffic loadings of near 100% are possible with frame sizes up to 7000 bytes. Above 7000 bytes the percent traffic loading has to be reduced to prevent dropped packets. and pause frame traffic for each link between cascaded switches. 200 180 Overhead (Mbps) direction, i.e.

This means that three times the overhead value must be used. Add all the application traffic (step 2.) with all the over head values (step 3.) and compare with the total available bandwidth. Example 1 Assuming gigabit devices are used with 9000-byte jumbo frames and a total of three cascaded switches.
