2924M XL DC
for
Service Provider
Networks
The Cisco Catalyst
®
2924M XL DC is a
10/100 autosensing Fast Ethernet switch
designed for Service Provider Networks
that combines outstanding performance,
ease of use, and integrated Cisco IOS
®
software. The Catalyst 2924M XL DC is
a DC-powered, flexible, and scalable
solution, ideal for aggregating Ethernet
and Fast Ethernet workgroups and
delivering dedicated 10 or 100 Mbps
connectivity for network components
with high-speed uplink modules, including
Gigabit Ethernet and ATM, to connect to
servers and LAN backbones.
The Catalyst 2924M XL DC switch, a
DC-powered member of the Catalyst 2900 Series
XL family, contains 24 10BaseT/100Base TX
ports and two versatile module slots to provide
unmatched expansion capabilities and high-speed
connectivity. The modular design allows users to
easily add 10BaseT/100BaseT, 100BaseFX,
Gigabit Ethernet, or Asynchronous Transfer
Mode (ATM) (OC-3) ports to increase port
density and deliver high-speed uplinks. With the
Gigabit Ethernet module, Catalyst 2924M XL
switches can be stacked (up to nine switches) with

the low-cost Cisco GigaStack
™
gigabit interface
controller (GBIC). The advanced Cisco
architecture incorporates a switch fabric of
3.2 Gbps and a forwarding rate of 3.0 million
packets per second (pps) to deliver wire-speed
performance across all ports.

The Cisco Catalyst 2924M XL DC switch meets
telcos’ critical physical requirements for depth
(maximum 12 inch depth), -48v DC power, and
Common Language Equipment Identification
(CLEI) codes. The Catalyst 2924M XL DC switch
is also NEBS Level 3-compliant.

Service Provider Networks
Service Providers [for example, Regional Bell
Operating Companies (RBOCs), Intra Exchange
Carriers (IXCs), Internet Service Providers and
Wireless companies] can use the Catalyst 2924M
XL DC to provide Ethernet connectivity between
network elements in central offices, points of
presence (POP), and Wireless/Mobile Switching
Centers that are provisioned with DC power.

Central Office
: Service Providers can use the
Catalyst 2924M XL DC in Central Offices as a
component of the Data Communications
Network (DCN). The DCN is an out-of-band
network that separates network management
traffic from customer service networks in order
to reduce complexity in managing the network.
