#18 - Analyzing the hardware of the industrial managed switch Stratix

Rockwell Stratix Layer 2 Managed switches were  developed in partnership with CISCO and  are widely used in industrial networks. They are responsible not only for the physical points of the network articulation in ring topology that makes the communication within the factory, but also for the management and orchestration of this complex communication between the devices. In this post we will show some points  of the Hardware part. 

The Switch is available in different number of ports, such as 20 ports:

• DIN-Rail mounted to be fitted inside an electrical panel
• 16 copper cable ports (in this example of 20 total ports): 
• Physical medium: Copper
• Bandwidth: 10 or 100 Mbps
• Example of Ethernet-IP communication protocol 
• Example topology: star
• doors number: 1 to 16
• Local devices on a local VLAN network (example IP 192.168.1.x): 
• PLC
• VFD
• Remote IOs
• etc
• 2 ports for SFP (small form-factor pluggable): 
• Physical medium: SFP Copper (for distance less than 100m) or SFP Fiber (for distance greater than 100m).
• Bandwidth :  10 or 100 Mbps
• Communication protocol example: Ethernet-IP
• Example topology: star
• ports number: 17 and 18
• Local devices on a local VLAN network (example IP 192.168.1.x): 
• PLC
• VFD
• Remote IOs
• etc

• 2 Gigabit ports:
• Physical environment: Copper (for distance less than 100m) or Fiber (for distance greater than 100m).
• Bandwidth :  10, 100 or 1000 Mbps
• Communication protocol example: OPC-UA
• Example topology: ring
• ports number: 1 and 2
• Industrial ring network devices
• Switches
• Servers (Supervisory)

This switch can be powered at 24VDC at two points for redundancy. Also observe the grounding points below:

It is possible to insert an SD card for backup:

The configuration can be done in several ways: Express Setup (recommended) or Console.

Alarms can also be configured and triggered through these relays. They can be used to alert power failure, high or low temperature, software license problems or with two external inputs.

Some of the features available depending on the model:

• CIP Sync: Protocol that allows synchronization with high precision of the clocks of the automation devices.
• REP (Resilient Ring Protocol): Protocol that guarantees the ring topology works, through connection between switches.
• NAT (Network Address Translation): Method that translates network addresses. In this case, this function is not available for the device described in this post.
