Cisco Catalyst 4900 Series

High-performance switching for datacenter top of rack applications and space
constrained LAN aggregation in branch deployments.
The Catalyst 4900 Series are a compact form factor (1-2RU) family of switches
providing wire speed GE and 10GbE connectivity and services for top of rack
server aggregation in the datacenter and for space constrained branch collapsed
core/distribution LAN aggregation. The Catalyst 4900 Series includes four Layer
2–4 fixed-configuration switches.
The Catalyst 4948 switch offers 48 ports of wire-speed 10/100/1000BASE-T with
four alternative wired ports that can accommodate optional 1000BASE-X Small
Form-factor Pluggable (SFP) optics.
The Catalyst 4948-10GbE switch offers 48 ports of wire-speed 10/100/1000BASE-T
with two wire-speed 10 Gigabit Ethernet (10GbE) uplinks via optional 10GbE (X2) optics.
The Catalyst 4928-10GbE switch offers 28 wire-speed Small Form-Factor Pluggable
(SFP) ports with two wire-speed 10 Gigabit Ethernet (10GbE) uplinks via optional
10GbE (X2) optics.
The Cisco Catalyst 4900M is a 320-Gbps, two-rack-unit (2RU) semi-fixed
configuration switch with 8 fixed wire-speed 10GbE ports on the base unit and 2
optional half-card slots for deployment flexibility. Three half-card modules provide
additional 10GbE density or 10/100/1000 copper ports. The 8 port half card
supports 1 GE SFPs via the TwinGig adapter.
All models provide exceptional reliability and serviceability, supporting optional
internal AC or DC 1 + 1 hot-swappable power supplies and a hot-swappable fan tray
with redundant fans.
These switches are available with either the IP Base Software image or the
Enterprise Services Software image. The Enterprise Services Software additionally
supports Shortest Path First (OSPF), Intermediate System-to-Intermediate System
(IS-IS), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway
Protocol (BGP).
