Data Sheet
Cisco 1548 Micro Switch 10/100 Cisco Networked Office Stack
The Cisco 1548 Micro Switch is an affordable, easy to use, 10/100 autosensing Fast Ethernet switch
for creating high-performance LANs in small offices and workgroups. A single Cisco Micro Switch
10/100 offers eight 10BaseT/100BaseTX switched ports, making it ideal for connecting
high-performance workstations and servers. The Cisco 1548 Micro Switch 10/100 also can be
deployed as the LAN backbone in larger office networks aggregating other devices, including the
Cisco 1528 Micro Hub 10/100.
Each switch port supports autosensing and autonegotiation
features to correctly set the communications speed and
duplex mode between connected devices. The Cisco 1548
Micro Switch 10/100 offers the key advantages of simple
configuration, low cost, optimal port density, high
performance, and flexibility.
The Cisco 1548 Micro Switch 10/100 is an integral
member of the Cisco Networked Office stack of networking
solutions designed for small businesses. Combined with the
Cisco 1600 router series and other products in the Cisco
Networked Office stack, the Cisco 1548 Micro Switch 10/
100 provides high-performance local-area networking with
reliable and affordable Internet access, and a secure
remote-access solution.
Key Features and Benefits
High Performance
• Eight 10BaseT/100BaseTX autosensing, autonegotiation
ports deliver Fast Ethernet performance where it is needed
most—to demanding workgroups and servers—while
preserving legacy 10BaseT connectivity.
• Full-duplex operation on each switched 10BaseT/
100BaseTX port delivers up to 200-Mbps of bandwidth to
end stations or servers and between switches.
• 800-Mbps switching capacity with up to 1.19 million
packets per second forwarding rate ensures continuous,
high-speed network operation.
Easy to Install and Use
• Installing a Cisco 1548 Micro Switch 10/100 does not
Cisco 1548 Micro Switch 10/100
require technical expertise. Automatic configuration and
self-test on startup ensures that the switch will function
• Color-coded ports on the rear panel of the unit enable
simple and accurate connection of hubs, PCs and
workstations, printers, fax servers, and other devices.
• LED indicators on each port of the Cisco 1548 Micro
Switch 10/100 provide comprehensive and convenient
visual management. LEDs indicate system and port status,
power, bandwidth utilization, speed (10 Mbps or 100
Mbps), and half-/full-duplex operation.
• Autonegotiation on each port automatically selects half- or
full-duplex transmission mode to optimize bandwidth.
Protects Networking Investment
• Supports existing 10BaseT and 100BaseTX equipment
• One year
minimizing network change and overall deployment costs.
Safety Specifications
