Quick Start Guide Cisco 300 Series Managed Switches
Welcome Thank you for choosing the Cisco 300 Series Managed Switch, a Cisco network communications device. This device is designed to be operational right out of the box as a standard bridge. In the default configuration, it will forward packets between connecting devices after power up.
Do not deploy the device in a location where any of the following conditions exist: • High Ambient Temperature—Refer to the following table for the high ambient temperature rating of each switch: Ambient Temperature Ratings Switch Model High Temperature SF300-24P 104 degrees Fahrenheit (40 Centigrade) SF300-24PP 113 degrees Fahrenheit (45 Centigrade) SF300-24MP 122 degrees Fahrenheit (50 Centigrade) SF300-48P 104 degrees Fahrenheit (40 Centigrade) SF300-48PP 122 degrees Fahrenheit (50 Centigrade)
Rack-Mount Placement STEP 1 Remove the four screws from each side near the front of the switch. Retain the screws for re-installation. (Do not remove the four screws from each side near the back of the switch.) STEP 2 Place one of the supplied spacers on the side of the switch so the four holes of the spacers align to the screw holes. Place a rack mount bracket next to the spacer and reinstall the four screws removed in Step 1.
There is a wall-mount kit packed with your switch. The dimensions for the mount kit are as follows: 1 3 2 196243 4 1 8 mm/0.4 in 2 22.2 mm/0.9 in 3 6.8 mm/0.3 in 4 17.6 mm/0.7 in Mount the managed switch to the wall by drilling two pilot holes 3.7 inches (95 mm) apart, attaching the provided anchors and screws to the wall, then sliding the switch into position on the screws. The switch should have a minimum of 5 inches (130 mm) of clearance on all sides.
STEP 3 Repeat Step 1 and Step 2 for each device you want to connect to the managed switch. NOTE Cisco strongly recommends using Cat5 or better cable for Gigabit connectivity. When you connect your network devices, do not exceed the maximum cabling distance of 100 meters (328 feet). It can take up to one minute for attached devices or the LAN to be operational after it is connected. This is normal behavior.
NOTE The switch can deliver a maximum of 15.4 Watts to any 10/100 or Gigabit PoE port. The 24MP, 28MP, 52P and 52MP models of the switch can deliver a maximum of 30 Watts to any PoE port. WARNING The switch is to be connected only to PoE networks without routing to the outside plant. CAUTION Consider the following when connecting switches capable of supplying PoE: The PoE models of the switches are PSE (Power Sourcing Equipment) that are capable of supplying DC power to attaching PD (Powered Devices).
Configuring the Cisco 300 Series Managed Switch 3 Before You Begin Verify the managing computer requirements in the product release notes. The switch can be accessed and managed by two different methods; over your IP network using the web-based interface, or by the Command Line Interface (CLI) through the console port. Using the console port requires advanced user skills.
NOTE Details on how to change the IP address on your computer depend upon the type of architecture and operating system you are using. Use the computer Help and Support functionality to search for “IP Addressing.” STEP 3 Open a Web browser window. If you are prompted to install an Active-X plug-in when connecting to the device, follow the prompts to accept the plug-in. STEP 4 Enter the switch IP address in the address bar and press Enter. For example, http://192.168.1.254. The Switch Login Page displays.
• 8 data bits • no parity • 1 stop bit • no flow control STEP 4 Enter a user name and password. User names and passwords are both case sensitive and alpha-numeric. The default username is cisco, and the default password is cisco. STEP 5 If this is the first time that you have logged on with the default username and password, the following message appears: Please change your password from the default settings. Please change the password for better protection of your network.
Pinging 192.168.1.254 with 32 bytes of data: Reply from 192.168.1.254: bytes=32 time<1ms TTL=128 If you cannot reach the switch, you should get a reply similar to the following: Pinging 192.168.1.254 with 32 bytes of data: Request timed out. Possible Causes and Resolutions Bad Ethernet connection: Check the LEDs for proper indications. Check the connectors of the Ethernet cable to ensure they are firmly plugged into the switch and your computer.
Features of the Cisco 300 Series Managed Switch 4 This section describes the exterior of the managed switches including ports, LEDs, and connections. Front Panel Ports The ports and LEDs are located on the front panel of the switch.
• The LEDs of the corresponding RJ-45 port light to respond to the SFP interface traffic. NOTE SG300-10SFP and SG300-28SFP have dedicated SFP ports. Their LED status and indication are the same as on the RJ-45 ports. Front Panel LEDs System LED—(Green) Lights steady when the switch is powered on, and flashes when booting, performing self tests, and acquiring an IP address. If the LED flashes Amber, the switch has detected a hardware failure. LINK/ACT LED—(Green) Located on the left of the port.
Console—The Console port is where you can connect a serial cable to a computers serial port for configuration using a terminal emulation program. 5 Returning the Device to the Factory Default Settings To use the Reset button to reboot or reset the managed switch, do the following: • To reboot the managed switch, press the Reset button for less than 10 seconds. • To restore the managed switch configuration to the factory default settings: 1.
