As shown in the above diagram, Ethernet Protected Switched Rings (EPSR) and 10 GbE modules allow the SwitchBlade x908 advanced modular switch, with a number of x900 switches or iMAPs, to form a high speed protected ring with sub 50ms failover. This feature is perfect for high performance at the core of your Service Provider network. Comprehensive, low latency Quality of Service (QoS) features operating at wire-speed provide flow-based traffic management with full classification, prioritization, traffic shaping, and min/max bandwidth profiles. These QoS features are ideal when you want to ensure maximum availability of voice, video and data services, and simultaneously manage customer service level agreements.
Providing maximum Gigabit Ethernet port density in a 3RU chassis, the SwitchBlade x908 has a large multicast group capacity, which allows you to offer the maximum number of video services to your customers - increasing your per-port revenue. A high degree of flexibility future-proofs your investment against changes in network infrastructure, topology, and physical link requirements. Future XEM modules will provide greater Ethernet connectivity options, allowing your network to adapt in response to business needs.
Fully operational with one PSU, the second PSU provides redundancy and the ability to support dual feed where needed. These internal PSUs eliminate the need for an external Redundant Power Supply (RPS), affording you more valuable rack space. This built-in redundancy guarantees the continued delivery of essential services.
