Features
The switch can be deployed as a broadband aggregation switch, aggregating 1000BASE-X SFP Ethernet traffic from other network devices to 10-Gigabit uplinks. The Cisco ME 4924-10GE switch has a
48-Gbps, nonblocking, full-duplex switching fabric, providing 102 million packets-per-second of switching capacity for high-speed applications.
A removable automatic variable speed fan tray for low noise operation at room temperature and removable and redundant 300 W AC or 300 W DC power supplies provide fault-tolerance protection for the switch. A faulty fan tray may be removed and replaced with a new one without taking the switch out of service. You may also replace a faulty power supply while the redundant supply provides uninterrupted power to the switch.
The following sections describe the switch features.
