Chapter 1 Overview of the Cisco Nexus 3000 Series Switches
Cisco Nexus 3548 and Cisco Nexus 3524 Switches
The Cisco Nexus 3172PQ is compatible with existing Gigabit Ethernet infrastructure. The 10 Gigabit
Ethernet interfaces can operate in either Gigabit Ethernet or 100-Mbps mode. Tabl e 1-18 lists the Gigabit
Ethernet SFP transceivers that are supported. 100-Mbps connectivity can be achieved by using
copper-based SFP transceivers (SFP-GE-T and GLC-T).
Cisco Nexus 3548 and Cisco Nexus 3524 Switches
The Cisco Nexus 3548 is a 1 rack unit (RU) switch that supports 48 fixed 1- and 10-Gigabit Ethernet
Small Form-Factor Pluggable (SFP+) ports, dual redundant, hot-swappable power supplies, four
individual, redundant, hot-swappable fans, one 1-PPS timing port, two 10/100/1000 management ports,
one console port, and one USB port. The power supply units and fan trays provide forward or reverse
airflow for cooling. The Cisco Nexus 3548 provides line-rate, Layer 2 and 3 switching at ultra low
latency and consumes low power.
Note The Cisco Nexus 3524 (N3K-C3524P-10G) is a Cisco Nexus 3548 switch but with only 24 ports active
and can be upgraded to use all 48 ports.It is the lowest entry point for main-stream top-of-rack (TOR)
data center deployments which offers wire-rate Layer 2 and Layer 3 switching with a comprehensive
feature set, including Algo Boost technology, and ultra-low latency.
