N3K-C3548P-XL is the Nexus 3548-XL Switch, with 48 SFP+. The Cisco Nexus 3000 Series Switches are a comprehensive portfolio of 1, 10, and 40 Gigabit Ethernet switches built from a Switch-on-a-Chip (SoC) architecture. Introduced in April 2011, this series of switches provides line-rate Layer 2 and 3 performance and is suitable for Top-of-the-Rack (ToR) architecture. This series of switches has established itself as a leader in High-Frequency Trading (HFT), High-Performance Computing (HPC), and big data environments by pairing high performance and low latency with innovations in performance visibility, automation, and time synchronization.

Product Details
The Cisco Nexus 3548-XL Switches are, respectively, Cisco Nexus 3548-X Switches with a faster CPU, running at 2.5 GHz; system memory increased to 16 GB; and bootflash memory increased to 16 GB. These enhancements allow the switches to support the Cisco NX-OS Data Management Engine (DME) model.
The Cisco Nexus 3548-XL have the following hardware configuration:
- ¡ñ48 fixed SFP+ ports (1 or 10 Gbps)
- ¡ñDual redundant hot-swappable power supplies
- ¡ñFour individual redundant hot-swappable fans
- ¡ñOne 1-PPS timing port, with the RF1.0 and 2.3 QuickConnect connector type
- ¡ñOne 10/100/1000 management port
- ¡ñOne RS-232 serial console port
- ¡ñTwo USB ports
- ¡ñLocator LED
- ¡ñLocator 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.
