3 Running Express Setup When you first set up the switch, you should use Express Setup to enter the initial IP information. This enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration. To run Express Setup: Step 1 Make sure that nothing is connected to the switch. During Express Setup, the switch acts as a DHCP server.
Step 7 Connect a Category 5 Ethernet cable to any 10/100 or 10/100/1000 Ethernet port on the switch front panel. 1 SYST RPS MASTR STAT DUPLX SPEED STACK MODE 1X 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 15X 17X 2X 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 31X 33X 34 35 36 37 38 39 16X 18X 40 41 42 43 44 45 46 47 Catalyst 3560G 48 SERIES PoE-48 47X 32X 34X 49 51 Connect the other end of the cable to the Ethernet port on your PC.
Step 11 Enter this information in the Network Settings fields: • In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only if you want to change the management interface through which you manage the switch. The VLAN ID range is 1 to 1001. • In the IP Address field, enter the IP address of the switch. In the IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask. • In the Default Gateway field, enter the IP address for the default gateway (router).
Step 14 (Optional) Enter this information in the Advanced Setting fields: • In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch by using the command-line interface (CLI). If you enable Telnet access, you must enter a Telnet password. • In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25 alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end.
Refreshing the PC IP Address After you complete Express Setup, you should refresh the PC IP address: • For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect the PC to the network. The network DHCP server assigns a new IP address to the PC. • For a statically assigned IP address, change it to the previously configured IP address.
3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if your browser offers this choice.) 4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network Assistant installation. Refer to the Network Assistant online help and the getting started guide for more information. Command-Line Interface You can enter Cisco IOS commands and parameters through the CLI.
5 Planning Switch Stacks Before connecting the Catalyst 3750 switches in a stack, keep in mind these planning considerations: • The size of the switch. See the“Technical Specifications” appendix of the Catalyst 3750 Switch Hardware Installation Guide for the switch dimensions. Stacking together switches of the same size makes it easier to cable the switches. • Length of cable. Depending on the configuration of your switch stack, you might need different sized cables.
Cabling Considerations These illustrations show the recommended Catalyst 3750 switch stack configurations with redundant StackWise cabling connections for optimized stack bandwidth. For more configuration examples, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com. Vertical Stacking 86586 In this example, the stack uses the 0.5-meter StackWise cable to make redundant connections. 86585 In this example, the stacks use both 0.
Side-By-Side Stacking 86825 In this example, eight switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables. 90532 In this example, nine switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables. Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable.
6 Rack-Mounting This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst 3750G-48TS switch. You can install and connect other Catalyst 3750 switches as shown in these illustrations. For alternate mounting procedures, such as installing the switch in a 24-inch rack or on a wall, and for additional cabling information, see the Catalyst 3750 Switch Hardware Installation Guide on Cisco.com.
Installation Warning Statements This section includes the basic installation warning statements. Translations of these warning statements appear in the Regulatory Compliance and Safety Information for the Catalyst 3750 Switch guide. Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 148 Warning To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113°F (45°C).
Warning If a redundant power system (RPS) is not connected to the switch, install an RPS connector cover on the back of the switch. Statement 265 Warning Class 1 laser product. Statement 1008 Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: 10/100/1000 Ethernet.
Attaching the Brackets Use four Phillips flat-head screws to attach the long side of the brackets to Catalyst 3750 switches in one of three mounting positions.
Rack-Mount the Switch Use the black Phillips machine screw to attach the cable guide to the left or right bracket. Use the four number-12 Phillips machine screws to attach the brackets to the rack.
Connect the StackWise Cables Follow these steps to connect the StackWise cable to the StackWise ports: Step 1 Remove the dust covers from the StackWise cables and StackWise ports, and store them for future use. Step 2 Insert one end of the StackWise cable into the StackWise port on the back of the switch. STACK 1 STACK 2 CONSOL E Step 3 Use the window in the StackWise cable to align the connector correctly. Secure the screws tightly.
Connect to the Switch Ports This section describes how to connect to the fixed switch ports, the SFP module ports, and the XENPAK module ports. Connect to 10/100 and 10/100/1000 Ports Follow these steps: Step 1 When you connect to servers, workstations, IP phones, wireless access points, and routers, insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/100 or 10/100/1000 port.
Install the SFP Modules and Connect to the Ports Follow these steps: Step 1 Grasp the module on the sides, and insert it into the switch slot until you feel the connector snap into place. 13 14 15 13X 16 17 18 19 20 21 22 23 Catalyst 37 50G SERIES 24 PoE-24 23X 25 27 14X 24X 26 28 SFP module Step 2 Insert an appropriate cable into the module port. Insert the other cable end into the other device.
Install the XENPAK Module and Connect to the Ports Follow these steps to install a XENPAK module into the XENPAK module slot on the front panel of the Catalyst 3750G-16TD switch: Step 1 Step 2 Remove the two Phillips-head retaining screws from the XENPAK module slot cover, and store them for later use. Remove the cover.
