When determining where to place the switch, be sure to observe the guidelines listed below:
A Catalyst 3500 XL switch can be installed in a 19-inch or 24-inch standard rack, on a wall, or on a table or shelf. This section contains procedures for installing a switch in each of these locations.
Before you begin the installation, decide how to mount the switch by reviewing the illustrations in this section. If you decide to mount the switch in a rack or on a wall, use the mounting brackets supplied with the switch.
To install the switch in a 19-inch or a 24-inch standard rack, follow the instructions described in these procedures:
Figure 2-1 and Figure 2-2 show how to attach a bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.
After the brackets are attached to the switch, use the four supplied Phillips machine screws (number 12) to securely attach the brackets to the rack, as shown in Figure 2-3.
After the switch is mounted in the rack, attach the power cord to the switch. If you are using the Cisco Redundant Power Supply (RPS), see the Cisco RPS documentation for installation instructions.
After the power is connected, the System LED turns amber for 2 seconds, and then it flashes green while the switch completes a series of power-on-self-tests (POST) described in the "POST Results" section.
We recommend attaching the cable guides to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack. If the switch is in a 19-inch or 24-inch rack, you can attach the cable guide to the left or right bracket by using the supplied black screw, as shown in Figure 2-4.
This section describes the steps required to attach the switch to a wall:
Use two of the supplied Phillips flat-head screws (number 8) to attach the long side of the bracket to the switch.
Figure 2-6 shows how to attach the brackets to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.
For best support of the switch and cables, make sure the switch is attached securely to a wall stud or to a firmly attached plywood mounting backboard, as shown in Figure 2-7.
After the switch is mounted on the wall, attach the power cord to the switch. If you are using the RPS, see the Cisco RPS documentation.
After the power is connected, the system LED turns amber for 2 seconds, and then it flashes green while the switch completes a series of self-tests described in the "POST Results" section.
Follow these steps to install the switch on a table or shelf:
Step 2 Place the switch on the table or shelf near an AC power source.
Step 3 Connect the power cord to the switch rear panel and to the power outlet. If you are using the RPS, see the RPS documentation for installation instructions.
After the power is connected, the system LED turns amber for 2 seconds, and then it flashes green while the switch completes the power-on self-tests (POST).
POST is a series of eight tests that run automatically to ensure that the switch functions properly. When the switch begins POST, the port status LEDs turn amber for 2 seconds, and then they turn green. The System LED flashes green, and the RPS LED turns off. As each test runs, the port status LEDs, starting with number 1, turn off. The port status LEDs for ports 2 to 8 each turn off in turn as the system completes a test.
When POST completes successfully, the port status LEDs return to the status mode display, indicating that the switch is operational. If a test fails, the port status LED associated with the test turns amber, and the system LED turns amber. Refer to "Troubleshooting," to determine a course of action if POST fails.
POST failures are usually fatal. Call Cisco Systems immediately if your switch does not pass post.
This section explains how to connect devices to the 10/100 and 1000BaseX ports.
The switch 10/100 Ethernet ports configure themselves to operate at the speed of attached devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have their speed and duplex parameters manually set can reduce performance or result in no linkage. To maximize performance, choose one of these methods for configuring the 10/100 Ethernet ports:
Follow these steps to connect to 10BaseT and 100BaseTX devices:
Step 1 When connecting to servers and workstations, connect a straight-through
Category 5 cable to an RJ-45 connector on the front panel, as shown in Figure 2-8.
Step 2 Connect the other end of the cable to an RJ-45 connector of the other device. The port status LED comes on when both the switch and the connected device are turned on.
The port status LED is amber while Spanning-Tree Protocol (STP) discovers the topology and searches for loops. This takes about 30 seconds, and then the port status LED turns green.
If the port status LED does not come on, the device at the other end might not be turned on, or there might be a cable problem or a problem with the adapter installed in the attached device. See "Troubleshooting," for solutions to cabling problems.
Step 3 Reconfigure and reboot the connected device if necessary.
Step 4 Repeat steps 1 through 3 to connect each device.
For detailed instructions on installing, removing, and cabling the GBICs (1000BaseSX module or the 1000BaseLX/LH module), refer to the GBIC documentation.
For detailed instructions on installing and cabling the GigaStack GBICs, see the Catalyst GigaStack Gigabit Interface Converter Installation Guide.
Follow these steps to connect to the port:
1. Remove the rubber plugs from the fiber-optic port on the module, and store them for future use.
2. Insert the SC connector in the fiber-optic receptacle, as shown in Figure 2-9.
 | Caution caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the fiber-optic port and cable from contamination and ambient light. |
Connect the GigaStack cable connector to the GigaStack GBIC as shown in Figure 2-10.
| Caution Do not create a loop in a stack configuration. |
A loop occurs when one of the following conditions occurs:
A loop causes excessive collision errors on the port and might cause the link to become unstable. This instability decreases performance on the links and disrupts communication between the switches in the stack. For proper configuration scenarios, see the Catalyst GigaStack Gigabit Interface Converter Installation Guide.
Use the supplied rollover cable to connect a terminal or PC to the console port. The terminal or PC must support VT100 terminal emulation. The terminal-emulation software---frequently a PC application such as Hyperterminal or Procomm Plus---makes communication between the switch and your PC or terminal possible during the setup program.
Follow these steps to connect the terminal or PC to the switch:
Step 2 Configure the baud rate and character format of the terminal or PC to match these console port default characteristics:
After you have gained access to the switch, you can change the port baud rate. See the Cisco IOS Desktop Switching Software Configuration Guide for instructions.
Step 3 Using the supplied rollover cable, insert the RJ-45 connector into the console port, as shown in Figure 2-13. See the "Console Port" section for a description of the pinout.
Step 4 Attach one of these supplied adapters to a PC or terminal:
Step 5 Insert the other end of the supplied rollover cable in the attached adapter.
Step 6 Boot the terminal-emulation program if you are using a PC or workstation.
You can assign the switch an IP address by two methods:
This section describes each method.
You can use an automatic setup program to assign IP information and to create a default configuration for continued operation. Later, you can use Cisco Visual Switch Manager (CVSM) or the command-line interface (CLI) to customize your configuration. To run the setup program, access the switch from the terminal or PC that you connected to the console port. (See the "Connecting a Terminal or PC to the Console Port" section.)
The first time you connect to the switch, the setup program prompts you for an IP address, a subnet mask, and the IP address of the default gateway. Contact your system administrator for these numbers:
Switch IP address | ___________.___________.___________._________ |
Subnet mask (netmask) | ___________.___________.___________._________ |
Default gateway (router) | ___________.___________.___________._________ |
Follow these steps to assign the IP addresses to the switch:
Step 1 Enter Y at the first prompt:
Continue with configuration dialog? [yes/no]: y
If this prompt does not appear, enter enable, and press Return. Enter setup, and press Return to start the setup program.
Step 2 Enter the switch IP address, and press Return:
Enter IP address: ip_address
Step 3 Enter the subnet mask (IP netmask) address, and press Return:
Enter IP netmask: ip_netmask
Step 4 Enter Y to enter a default gateway (router) address:
Would you like to enter a default gateway address? [yes]: y
Step 5 Enter the IP address of the default gateway (router), and press Return:
IP address of the default gateway: ip_address
Step 6 Enter a host name, and press Return:
Enter host name [Switch]: host_name
Step 7 Enter a secret password (which ensures switch security), and press Return:
Enter enable secret password: secret_password
Step 8 Enter Y to configure this switch as the cluster command switch. Enter N to configure it as a standalone switch.
Would you like to enable as a cluster command switch? y
Step 9 Assign a name to the cluster, and press Return:
Enter cluster name? cls_name
Step 10 The initial configuration displays:
The following configuration command script was created:
interface VLAN1
ip address ip_address ip_netmask
ip default-gateway ip_address
enable secret 5 $1$jJql$VA6U.6uTjsa56Xx2yy/t30
snmp community private rw
snmp community public ro
cluster enable cls_name
!
end
!
Use this configuration? [yes/no]:
Step 11 Verify that the addresses are correct.
Step 12 Enter Y, and press Return. If the addresses are not correct, enter N, press Return, and begin again at Step 1.
When you see the message "Press RETURN to get started," the setup program is complete. You can use your browser and CVSM or use the CLI to manage the switch.
You can use BOOTP to assign IP information to a 3500 XL switch. A database with a list of physical MAC addresses and corresponding IP addresses must be set up on the BOOTP server. Other optional information, such as the corresponding subnet masks and default gateway addresses, can also be stored in the database. The switch must be able to access the BOOTP server through one of its ports.
If the switch starts and no IP address has been assigned, it transmits a BOOTP broadcast request to all of its connected ports, requesting a mapping for its physical MAC address. A valid response includes the IP address, which is mandatory, and the subnet mask and the default gateway, which are optional.
The reception of a valid BOOTP response immediately activates the rest of the system protocol suite, without requiring a system reset. The running configuration is set, but the saved configuration in Flash memory is not automatically updated. To save the IP information, log in to the CLI, and enter the write memory command. The IP information is then preserved, and the switch does not issue BOOTP messages the next time it resets.
After you assign IP information, the switch can operate with the default configurations shown in Table 2-1.
