Product Overview
The Cisco ME 4924-10GE Ethernet switch, also referred to as the switch, is a metro Ethernet switch that
can be used as user facing provider edge aggregation equipment to connect to service provider customer
routers, switches, or other devices. This chapter provides a functional overview of the switch:
• Features, page 1-1
• Front Panel Description, page 1-3
• Rear Panel Description, page 1-7
• Management Options, page 1-8
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.
Hardware Features
The Cisco ME 4924-10GE hardware provides:

For information about port numbering, see the “Front Panel Description” section on page 1-3
• 2 power supply bays that support AC or DC input and power redundancy
For instructions on installing power supply units, see Chapter 3, “Connecting the Power Supply.”
• Layer 2, Layer 3, and Layer 4 switching services
• Two 10-Gigabit Ethernet uplink ports using X2 interfaces
