For security reasons, there is no reset button on the switches. If you need to reset the switch to factory settings, you will need a USB C cable (B - older models) and SIMULand.v4 configuration software.

Procedure

Click USB in the Conectivity menu, click Reset (Factory Default) in the following window and reset the switch to factory settings.

Note: For Windows 8.1 and earlier operating systems, you may need to install the USB driver.

Yes. A USB factory reset will restore the device to factory settings.

Default parameters
IP address - printed on the switch label
Mask - 255.0.0.0
Gateway - 10.1.0.1

In Simuland.v4, which always contains the latest firmware available for the switch.

After upgrading the switch, the switch will be set to its default settings, except for the IP, mask, gateway and ring.

Not really. After the switch upgrade, only the settings, IP, mask, gateway and ring will be preserved. The rest of the configuration will be default.

The mechanical and electrical parameters of SFP modules and slots are defined in the MSA (multi-source agreement). This ensures mutual compatibility between SFP module manufacturers and SFP slots of network elements. The SFP module includes an EEPROM. It stores information about the module type, supported speed, optical interface type, etc. The most widely used standards in IT are 100BASE-LX and 1000BASE-LX standards (LC connectors) with 2-fiber communication. This has probably also led to the fact that some commercial switches do not support the more modern single-fiber 100BASE-BX and 1000BASE-BX standards. Specifically, this refers to Byte 6 in the EEPROM (Ethernet Compliance Codes). For the above reasons, all BX-1000-...SFP modules have bit 1 (1000BASE-LX) set in Byte 6 and BX-1000-...SFP modules have bit 4 (100BASE-LX) set in Byte 6. The modules are then easily detected even by a switch that does not implement 100/1000BASE-BX support.

The recommended line load is 75% of the total data throughput.

Yes, of course, this option is available for the LAN-RING system. Only in this case, we recommend disabling the ringing function in the switch configuration (None) or switching LAN-RING to Rapid Spanning Tree Protocol (RSTP-M).

‌

The PoE function is factory set to "disable". Therefore, individual ports to which cameras or PoE-enabled devices are connected must be enabled in the configuration. If PoE does not start even after activation, the switch allows you to enable the Ignore Detect feature.

If the distance between the camera and the switch is longer than 100 m, we use a LAN-EXT solution. This is a device that can repeat the route of the link, even several times in a row.

LAN extenders

It is annoying to climb a pole and restart the camera or drive 100 km when the camera freezes. For this reason, we have added an IP Watchdog feature to the switches that monitors the camera address and automatically restarts PoE if communication is lost.

IP Watchdog is not only used to restart PoE, but can also monitor any IP address and in case of IP address failure, it can switch any contact in the LAN-RING network or trigger any other configured event.

I have observed different RSTP behavior of your switch compared to a competing switch in the following situation. There are two switches in the network connected to each other by a fiber optic link. Egress filtering is enabled on one of these devices (Egress filtering: No unknown destination address). However, only one switch is available at this time because the link is blocked by the RSTP protocol. However, if I replace the unavailable switch with a competing device with a similar configuration, both switches are available.

Egress filtering causes BPDU frames to be sent only in one direction because the other direction is filtered. This causes the first switch to know about the second, but the second switch does not know about the first. This condition is handled by the so-called "contention mechanism". This was incorporated into the 802.1D-2004 standard and solves the problem you mentioned by blocking the link to prevent loops. Our implementation of the RSTP protocol complies with this standard. Other vendors may have a different implementation of the RSTP protocol based on an older standard that did not include a "dispute mechanism".

Yes, the switch allows you to respond to the input state of a remote device by data shutting down the port. PoE remains active, so there is no need to wait for camera initialization on recovery, it is available immediately.
