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 Cisco’s 4500 Series modular switches, but is distinguished
by a 1-RU design that is ideal for top-of-rack server aggregation. The Cisco
Catalyst 4900 Series includes two Layer 2–4 fixed-configuration switches.
Cisco 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. Cisco Catalyst 4948-10GE switch
offers 48 ports of wire-speed 10/100/1000BASE-T with two wire-speed
10 Gigabit Ethernet 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).
