Cisco Small Business SLM Series Smart Switches Administration Guide 1

Getting Started

Thank you for choosing the Cisco Small Business Series Smart Gigabit Ethernet

Switch. The Smart Gigabit Ethernet Switches are cost-effective switching

solutions ideal for small businesses, the network edge, or workgroups within

larger organizations. These easy-to-install, high speed switches offer many of the

same Quality of Service and Security features found in more expensive full Layer 2

managed switches but without their complexity. The Smart Switches offer the

following interfaces:

•The SLM2024 and SLM2048 offer twenty four (24) or forty eight (48)

Gigabit copper ports, with two (2) shared copper or optical (SFP) uplink

interfaces for connecting the switch to the core network.

•The SLM224G, SLM224P, SLM248G, and SLM248P offer twenty four (24) or

forty eight (48) 10/100 copper ports, with two (2) shared Gigabit copper or

optical (SFP) uplink interfaces for connecting the switch to the core

network.

The Smart Switch’s simplified user interface is an intuitive management tool

enabling you to quickly utilize the comprehensive feature-set of the switch,

resulting in a better optimized network. The user interface is a web based

application that uses Microsoft Internet Explorer 6.0 or later, or Firefox 5.0 or later.

Starting the Application

To open the User Interface:

STEP 1 Open a web browser.

NOTE The default IP address is 192.168.1.254. If you have changed the IP address

or are using DHCP to assign it, enter the new IP address instead. The

computer you use for configuration should be on the same subnet as the

Switch.
