FL SWITCH SFN… Five- and Eight-Port Standard Function Ethernet Switches with Narrow Housings – Gigabit as an Option AUTOMATION Data Sheet 2732_en_D 1 © PHOENIX CONTACT 2011-01-26 Description 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). 2 – – 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. – – Features 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 loading – 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.

Invalid or faulty data packets (> 1522 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 addresses in its address table with an aging time of 5 minutes. This is important when more than one termination device is connected to one or more ports. In this way, several independent subnetworks can be connected to one switch. A restart deletes the entire address table. – Figure 9 Switching Characteristics 5-port fiber optic ports Quality of Service (QoS): IEEE 802.1P/Q The FL SWITCH SFN… switches are capable of reading Ethernet packets that have already been assigned a priority level by a managed switch. In cases of heavy traffic, packets with a priority level between 4 PHOENIX CONTACT 10 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. Fewer but larger packets, containing fewer overall overhead bytes, increase the overall network efficiency.

Jumbo 2732_en_D FL SWITCH SFN…GT… Jumbo Frame Capability Jumbo Frame Performance Factors The switch’s frame buffer size, the size of the frames (bytes/frame) and overall traffic loading of the network (bandwidth) impact the overall application performance. In the following sections, the loading per port is compared with the maximum frame size. At packet (frame) sizes over 3000 bytes, the switch will start sending pause frames to control the traffic flow (see vertical line on Figure 11 and Figure 12). As the size of the frame increases, the sending of pause frames increases. Figure 11 and Figure 12 indicate the maximum loading per port that can occur (for each jumbo frame size) until the buffer is overloaded and packets start to be dropped. Figure 11, Figure 12, and Figure 13 display traffic loading for 1000 Mbps (gigabit) data rates. For 100 Mbps data rates divide the y axis numbers by 10. 9.3 Application Guidelines The use of jumbo frames in industrial applications typically falls into two major application classes: – Bidirectional data transfers: usually caused by larger data file exchanges between controllers or PC applications. These may use jumbo frames in both directions (read/write) between the industrial devices. – Unidirectional data transfer: typically found in networks where security cameras or vision inspection equipment feed back to a centralized monitoring station. In these cases, the vast majority of the traffic flows in one PHOENIX CONTACT 11 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., security images from a camera to the network, with only a few, normal size transmissions containing control commands going the opposite direction. 160 140 120 100 80 60 40 20 0 2000 3000 4000 5000 6000 7000 8000 9000 Frame size (bytes) Figure 13 Traffic loading (Mbps) 1000 800 9.4 600 400 200 0 2000 3000 4000 5000 6000 7000 8000 9000 9600 Frame size (bytes) Maximum loading Pause frame threshold Figure 11 Maximum bidirectional traffic loading per port (FL SWITCH SFN 8GT) Unidirectional data transfer guidelines In applications where the data flow is predominantly in one direction, such as cameras and vision systems, near 100% loading is possible using jumbo frames. 1000 Traffic loading (Mbps) 900 800 Overhead/cascaded switch vs. frame size Calculating Total Network loading with cascaded (trunk topology) switches Because of the buffer size considerations when using jumbo frames, network bandwidth loading should be planned in advance to prevent packet loss. 1. Determine the total application traffic load for the connected devices. Add all the traffic loads from each device that will be connected to the switch and transferred to the main trunk line. When using cameras or vision systems, the bandwidth usage per device can be high (see Table 2). Actual numbers may vary depending on the camera or device type used. Table 2 Typical bandwidth load Typical Camera Settings 60 frames per second 750 x 640 pixels per frame 700 600 500 Color Depth (bits/pixel) 8 12 16 24 32 Typical Traffic Load (Mbps) 182 275 366 550 732 400 2. 300 200 100 0 2000 3000 4000 5000 6000 7000 8000 9000 9600 Frame size (bytes) Maximum loading Pause frame threshold Figure 12 Maximum unidirectional traffic loading per port (FL SWITCH SFN 8GT) When cascading devices in a trunk topology, up to 18 Mbps of the available bandwidth is required to support overhead 2732_en_D 3. Add all the application traffic from all connected switches and compare to the maximum network capacity. As the trunk traffic passes from switch to switch, add the total application device traffic from all the switches. The traffic load on the trunk ports cannot be greater than the total bandwidth available (1000 Mbps for gigabit and 100 Mbps for Fast Ethernet ports). Determine the traffic load for bandwidth consumed by application overhead and pause frames (see Figure 13). After the first switch, add this amount for each additional switch segment. PHOENIX CONTACT 12 FL SWITCH SFN… 4. As an example, if a total of four switches are connected together, there will be a first switch then three additional switched segments. 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. Each switch has one 8 bit/pixel camera plus 10 Mbps of miscellaneous traffic from other ports. Example 2 To take advantage of the bandwidth not used in example 1, assume one of the cameras is now required to operate at 12 bits per pixel. The increased camera color depth increases the traffic load to a total of 639 Mbps. Combined with the 360 Mbps overhead with a 9000-byte frame size, the total bandwidth is 999 Mbps. While technically within the capability of a 1000 Mb switch, any additional traffic across the transmission line could result in frame loss. Figure 14 depicts an example with three cameras connected to individual switches. Each camera is configured for an 8 bits per pixel color depth, creating a load of 182 Mbps per camera (see Table 2) with a total traffic load of 546 Mbps. Frame size is configured to 9000 bytes creating an overhead of 180 Mbps (see Figure 13) for each cascading switch for a total of 360 Mbps. 1 P 2 o w e r E T 1 1 0 3 d 4 g e HP LP 2065 US P 2 o w e r E T 1 1 0 3 d FL SWITCH SFN 8TX Ord.-No.: 2891929 US Figure 14 input 160 Mbps FL SWITCH SFN 8TX Ord.-No.: 2891929 US FL SWITCH SFN 8TX Ord.-No.: 2891929 US / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X1 X2 X1 X2 X1 100 100 100 100 100 / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X3 X4 X3 X4 X3 X4 100 100 100 100 100 / LNK ACT X2 100 100 / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X5 X6 X5 X6 X5 X6 100 100 100 100 100 100 / / / / / LNK ACT LNK ACT LNK ACT LNK ACT LNK ACT / LNK ACT X7 X8 X7 X8 X7 X8 100 100 100 100 100 100 e _ a u o t + input 182 Mbps 182 Mbps + 4 g HP LP 2065 180 Mbps FL SWITCH SFN 8TX Ord.-No.: 2891929 US Figure 15 180 Mbps / LNK ACT / LNK ACT / LNK ACT / LNK ACT X2 X1 X2 X1 X2 100 100 100 8000-byte frame size example 100 / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X3 X4 X3 X4 X3 X4 100 100 100 100 100 100 / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X5 X6 X5 X6 X5 X6 100 100 100 100 100 100 / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT / LNK ACT X7 X8 X7 X8 X7 X8 100 100 100 100 100 100 182 Mbps 275 Mbps US / LNK ACT X1 100 182 Mbps FL SWITCH SFN 8TX Ord.-No.: 2891929 / LNK ACT 100 a u to 160 Mbps FL SWITCH SFN 8TX Ord.-No.: 2891929 1 _ One possible solution is to change the frame size to 8000 bytes, reducing the overhead (see Figure 15). The reduced frame size results in a total overhead of 320 Mbps. Combined with the camera traffic load, the resulting bandwidth requirement is 959 Mbps, allowing some space for additional traffic. 182 Mbps 9000-byte frame size example Adding the camera data and overhead together indicates a total traffic load of 906 Mbps, leaving 94 Mbps of the 1000 Mbps total unused. 2732_en_D PHOENIX CONTACT GmbH & Co.
