Hello, we have a problem with RUT-955 connectivity with ethernet switch. Switch is connected with RUT-955 through switch gbic port with UF-RJ45-1G Cooper Transeiver and router does not see switch and their devices. If I connect switch to router through rj45 port I can access switch and their devices. It looks that something wrong with switch or its gbic port, but if I connect my laptop with switch through this cooper transeiver I can access it and ping it. Tried with other model switches. Is there any possibilly to solve this problem?
