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: middot, 48 fixed SFP+ ports (1 or 10 Gbps) middot, Dual redundant hot-swappable power supplies middot, Four individual redundant hot-swappable fans middot, One 1-PPS timing port, with the RF1.0 and 2.3 QuickConnect connector type middot, One 10/100/1000 management port middot, One RS-232 serial console port middot, Two USB ports middot, Locator LED middot, 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.
