The Cisco Nexus 3548 and 3524 have the following hardware configuration:
● 48 fixed Enhanced Small Form-Factor Pluggable (SFP+) ports (1 or 10 Gbps); the Cisco Nexus 3524 enables only 24 ports
● Dual redundant hot-swappable power supplies
● Four inpidual redundant hot-swappable fans
● One 1-PPS timing port, with the RF1.0/2.3 QuickConnect connector type*
● Two 10/100/1000 management ports
● One RS-232 serial console port
● One USB port
● Locator LED
● Locator LED button
Support for both port-side exhaust and port-side intake airflow schemes is available. Port-side exhaust airflow is useful when the port side of the switch sits on a hot aisle and the power supply side sits on a cold aisle. Port-side intake airflow is useful when the power supply side of the switch sits on a hot aisle and the port side sits on a cold aisle.
Colored handles on each fan or power supply clearly indicate the airflow direction, as seen in Figures 2 and 3.

Cisco Nexus 3548x and 3524x Switches
The Cisco Nexus 3548x and 3524x Switches (Figure 4) are the next generation of the Cisco Nexus 3500 platform. Like the previous generation, these switches are compact 1RU form-factor 10 Gigabit Ethernet switches and provide line-rate Layer 2 and 3 switching with ultra-low latency. In addition, they consume 25% less power. This new generation introduces powerful hardware-based multicast NAT and latency monitoring capabilities and a second USB port for easier manageability.
