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 Verify that no devices are connected to the switch, because during Express Setup, the switch acts as a DHCP server.
Step 7 Connect a straight-through Category 5 Ethernet cable (not provided) to any 10/100 or 10/100/1000 Ethernet port on the switch front panel and to the Ethernet port on the PC.
Step 12 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 and to which you assign IP information. 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.
Step 14 Click Submit to save your settings, or click Cancel to clear your settings. When you click Submit, the switch is configured and exits Express Setup mode. The PC displays a warning message and then attempts to connect with the new switch IP address. If you configured the switch with an IP address that is in a different subnet from the PC, connectivity between the PC and the switch is lost. Step 15 Disconnect the switch from the PC, and install the switch in your production network.

5 Rack-Mounting This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst 2950G-48-EI switch. You can install and connect other Catalyst 2950 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, refer to the Catalyst 2950 Switch Hardware Installation Guide on Cisco.com.
Installation Warning Statements This section includes the basic installation warning statements. Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 148 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.
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 Statements for Connecting to DC Power These statements apply when connecting a Catalyst 2950G-24-EI-DC or Catalyst 2950ST-24 LRE 997 switch to DC power. Warning When installing the unit, always make the ground connection first and disconnect it last.
Attaching the Brackets Use six Phillips flat-head screws to attach the long side of the brackets to Catalyst 2950G-48-EI, 2950SX-48-SI, or 2950T-48-SI switches in one of three mounting positions. Use four Phillips flat-head screws to attach the long side of the brackets for all switches other than the Catalyst 2950G-48-EI, 2950SX-48-SI, or 2950T-48-SI models.
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 to the Switch Ports This section describes how to connect to the fixed switch ports and to the SFP and GBIC module ports. Connect to 10/100 and 10/100/1000 Ports Follow these steps: Step 1 Step 2 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. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.
Install SFP and GBIC 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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Catalyst 29 50 SERIES 16 Catalyst 29 50 SERIES 1 15X 2 1 2 1 16X 2 SFP module Step 2 GBIC module Insert an appropriate cable into the module port. Insert the other cable end into the other device.
6 Connecting to DC Power To connect the Catalyst 2950G-24-EI-DC or Catalyst 2950ST-24 LRE 997 switch to a DC-input power source, follow the steps in this section.
Step 3 Slide the exposed area of the 6-gauge wire into the ground lug, and use the crimping tool to crimp the lug to the wire. Step 4 Using the ratcheting screwdriver, torque the ground lug screws to 15 lbf-in. (240 ounce-force inches [ozf-in.]) to attach the ground lug to the switch. CONSOL E Wiring the DC Input Power Source Follow these steps: Step 1 On the terminal block connector, identify the positive and negative feed positions.
Step 4 Step 5 Using the ratcheting torque screwdriver, torque each terminal block captive screw (above the installed wire leads) to 4.5 lbf-in. (72 ozf-in.). Insert the terminal block plug in the terminal block header on the rear panel of the Catalyst 2950G-24-EI-DC switch or on the front panel of the Catalyst 2950ST-24 LRE 997 switch. Return Negative Return Negative Feed A Feed B 36 - 72V 1 - 0.5A A B Step 6 Caution 18 Move the circuit-breaker handle for the DC power source to the on position.
