Fixed-configuration switches offering high-performance,
rack-optimized server switching for organizations of
all sizes.
The Cisco Catalyst 4900 Series is based on the proven hardware and software
architecture of the Cisco Catalyst 4500 Series modular switches, but is
distinguished by a 1-RU design that is ideal for top-of-rack server aggregation.
The Catalyst 4900 Series includes two 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. Both
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).
