Cisco Network Equipment Chassis

The D9190 chassis features dual-redundant and hot-swappable power supplies. It has the capacity to hold up to six modules. The chassis supports advanced internal common synchronization mechanisms that can be used to synchronize the various services being hosted. Dedicated management and auxiliary input ports are also provided for control system monitoring and communication. The PowerVu Conditional Access (CA) modules are field-replaceable to allow for fast service with minimum downtime. A contact-closure output is used to signal a major alarm to the control system when it is active.
