The Cisco® MGX® 8000 Series Multiservice Switches are a scalable family of multiservice switches, scaling from 1.2 Gbps to 180 Gbps redundant switching capacity and from DS0 to OC-192/STM-64 interface capacity. This scalability provides exceptional savings and efficiency for network operations and services growth. The Cisco MGX 8000 family includes the Cisco MGX 8850, MGX 8850/B, MGX 8830/B and MGX 8950 Multiservice Switches.
The Cisco MGX-XM60 Switching Module is the switch fabric that powers the Cisco MGX 8950 Advanced ATM Multiservice Switch. The Cisco MGX-XM60 provides 60 Gbps of full-duplex nonblocking switching capacity. Each Cisco MGX 8950 can be configured with up to four Cisco XM-60s to provide 240 Gbps of switching capacity for the system.
The Cisco MGX-XM60 Switching Module meets service providers' demand for carrier-class availability by offering hot-standby, load-sharing redundancy. (Refer to Figure 1.)

Technical Specifications
The Cisco MGX-XM60 Switching Module has the following primary features:
• Single-height card
• 60-Gbps nonblocking crosspoint switch fabric
• Dynamic sharing of capacity across multiple Cisco XM-60s, allowing for N + 1 redundancy
• Four installed in each Cisco MGX 8950 for 240-Gbps total capacity, 180-Gbps redundant capacity
• Hot card insertion/removal
• Complete separation from control processor, allowing data forwarding in the event of control card failure
