This Management and Switch Card used Broadcom 12 Gigabit switching solution to provide non-blocking traffic for gigabit bandwidth services. With two management and switch cards for network connection also can be used to support fully redundancy feature for network protection. It means anyone network failure, services still can be continued due to this protection. This non-blocking switching capability design with four gigabit uplinks including RJ45 and Small Form Factor (SFP) interfaces are ideal solution for flexible deployment in variety network and topology applications such as ring or tree topology.
