Data Sheet
Cisco 1548 Series Micro Switch 10/100
The Cisco 1548 series Micro Switch products are affordable autosensing 10/100 Fast Ethernet switches for creating high-performance LANs in enterprise remote branch offices or small and growing businesses. For customers whose bandwidth requirements have outgrown their legacy 10BaseT networks, the eight-port Cisco 1548M and Cisco 1548U switches offer dedicated 10/100 Autosensing Fast Ethernet connections, ideal for aggregating workgroups or connecting Ethernet and Fast Ethernet desktops.
The Cisco 1548M switch provides the most powerful and cost-effective Fast Ethernet solution in its class. Embedded Simple Network Management Protocol (SNMP) and Remote Monitoring (RMON) capabilities provide management, monitoring, and analysis. A Web-based management interface common to most Cisco stackable LAN products allows network managers to manage a switch from anywhere on the Internet through a standard Web browser. The Cisco 1548M Micro Switch 10/100 also supports four port-based VLANs for enhanced performance, management, and security. And, because management functionality is embedded within the Cisco 1548M, there is no need to purchase additional management modules.
The Cisco 1548U delivers dedicated 10/100 autosensing Fast Ethernet in an extremely affordable solution. For customers who want to deploy new bandwidth intensive applications but don't require management, the Cisco 1548U Micro Switch 10/100 is ideal.
The Cisco 1548 series Micro Switch 10/100 products are part of Cisco Networked Office (CNO) stack, a complete networking solution for enterprise branch offices and small and growing businesses. The CNO suite of stackable desktop products and software is affordably priced and delivers secure Internet access, high-performance local-area networking, and flexible remote access.

Key Features/Benefits
Exceptional Performance
- Eight 10BaseT/100BaseTX autosensing, autonegotiating switched ports deliver Fast Ethernet performance where it is needed most, while preserving your investments in legacy 10BaseT equipment.
- Full-duplex operation on each switched 10BaseT/100BaseTX port delivers up to 200-Mbps of bandwidth to end stations or servers and between switches.
Powerful and Cost-Effective Management
- Built-in HTTP server provides easy-to-use Web-based management interface through a standard browser such as Netscape Navigator or Microsoft Explorer. This Web-based management application provides easy-to-use, graphical configuration and monitoring options. (Cisco 1548M only.)
- SNMP and Telnet interface support delivers comprehensive in-band management, and command line interface (CLI)-based management console provides detailed out-of-band management. (Cisco 1548M only.)
- Cisco Discovery Protocol (CDP) enables a CiscoView network management station to automatically discover the switch in a network topology. (Cisco 1548M only.)
- Manageable through CiscoWorks Windows network management software on a per-port and per-switch basis providing a common management interface for Cisco routers, switches, and hubs. (Cisco 1548M only.)
- Support for up to four port-based VLANs for increased LAN performance and security. (Cisco 1548M only.)
- RMON software agent supports four RMON groups for enhanced traffic management, monitoring, and analysis. (Cisco 1548M only.)
- Switched Port Analyzer (SPAN) port permits high-performance traffic monitoring of a single port from a single network analyzer or RMON probe. (Cisco 1548M only.)
- Extensive per-port LEDs for power, port status, speed, and duplex indication provide easy and comprehensive visual management of the system.
Flexibility
- Autosensing and autonegotiating capabilities on all ports provide outstanding flexibility for deployment within a diverse network environment of equipment and technologies.
- Support for 4096 (4K) Media Access Control (MAC) addresses on the Cisco 1548M provides significant growth opportunity in number of end users supported by the network. The Cisco 1548U supports 2048 MAC addresses.
Ease of Use and Deployment
- An internal power supply provides single, compact design without external connections or devices.
- Autosensing on each port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing the deployment of the switch in mixed 10 and 100BaseT environments.
- Autonegotiating on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
- Extensive per-port LEDs for power, port status, and speed and duplex mode indication provide easy and comprehensive visual management.
- ConfigMaker management software common to all Cisco Networked Office products allows for easy configuration and deployment of an entire stack of Cisco products.
Single Vendor Solution and Support
- Warranty includes return to factory for free repair as long as you own the product. Power supply and fan are covered for first five years of ownership.
- When combined with a Cisco 1600 series or 1720 router and other Cisco Networked Office stack components, the Cisco 1548 series Micro Switch 10/100 products offer a complete LAN/WAN solution that is easy to install, manage, operate, and expand.
- Cisco Systems offers complete technical support and service for all Cisco Networked Office stack products, whether purchased separately or in combination with other Cisco products.
