When determining where to place the switch, be sure that the following conditions are met:
A Catalyst 2900 series switch can be installed in a 19-inch or 24-inch standard or telco rack, on a wall, or on a table or shelf. You can mount the switch in a rack or on a wall using the mounting brackets supplied with the switch.
This section describes the following steps to install the switch in 19- and 24-inch standard and telco racks:
Depending on your installation, you might have to first replace the screws in the switch chassis with screws for the mounting brackets. Decide how you are going to mount the switch by reviewing the illustrations in this section. Remove the screws as the first step in attaching the bracket. Figure 3-1 shows the screws to remove, as needed.
The bracket orientation and the screws you use depend on whether you are attaching the brackets for a 19-inch or 24-inch rack. Use two of the supplied screws to attach each bracket, according to the following guidelines:
Figure 3-2, Figure 3-3, and Figure 3-4 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 to securely attach the brackets to the rack, as shown in Figure 3-5.
After the switch is mounted in the rack, attach the power cord to the switch. If you are using the redundant power system (RPS), see the Cisco RPS documentation for installation instructions.
After the power is connected, the System LED turns green, and the switch starts a series of self-tests described in the "Reading 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 3-6. The cable guides for the modular switches require two screws.
This section describes the steps required to attach the switch to a wall:
The bracket orientation and the screws you use depend on whether you are attaching the brackets for parallel or vertical wall-mounting. Use two of the supplied screws to attach each bracket, according to the following guidelines:
Figure 3-7 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 3-8.
After the switch is mounted in the rack, attach the power cord to the switch. If you are using the redundant power system (RPS), see the Cisco RPS documentation.
After the power is connected, the System LED turns green, and the switch starts a series of self-tests described in the "Reading 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 green, and the switch starts a series of self-tests described in the "Reading POST Results" section.
When the POST completes successfully, all the port status LEDs blink once and go off, 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.
POST failures are almost always fatal. Call Cisco Systems immediately if the switch does not pass POST. See the "Understanding POST Results" section for a test-by-test description of the POST.
This section provides procedures for connecting to the 10/100 ports, the 100BaseFX ports, and the console port.
The Catalyst 2900 series 10/100 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 link. To maximize performance, choose one of these methods for configuring the 10/100 ports:
Follow these steps to connect to 10BaseT or 100BaseTX devices:
Step 1 When connecting to servers and workstations, insert a straight-through
Category 5 cable into an RJ-45 connector, as shown in Figure 3-9.
Step 2 Insert the other end of the cable in the 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.
Follow these steps to connect to one of the fixed 100BaseFX ports:
Step 1 Remove the rubber plugs from the fiber-optic port and store them for future use.
Step 2 Insert the connector into the fiber-optic receptacle, as shown in Figure 3-10.
 | Caution Do not remove the rubber plugs from the fiber-optic port or the rubber 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. |
Follow these steps to connect the terminal or PC to the switch:
Step 1 Be sure that your PC or terminal-emulation software is configured to communicate with the switch via hardware flow control.
Step 2 Configure the baud rate and character format of the terminal or PC to match the following default characteristics of the console port:
After you have gained access to the switch, you can change the baud rate of the port. See the "System Configuration" section for instructions on how to change the baud rate.
Step 3 Using the supplied rollover cable, insert the RJ-45 connector into the console port, as shown in Figure 3-11. 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 into the attached adapter.
Step 6 Boot the terminal-emulation program if you are using a PC or workstation.
You can assign IP information to the switch after you have attached a terminal or PC with emulation software. When the switch has an IP address, you can continue the configuration through the web-based manager software.
The first time you connect to the switch, the setup program prompts you for an IP address, subnet mask, and 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 Be sure the rollover cable is connecting a PC or terminal serial port to the console port. The data characteristics are 9600, 8, 1, no parity.
Step 2 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 3 Enter the switch IP address, and press Return:
Enter IP address: IP_address
Step 4 Enter the subnet mask (IP netmask) address, and press Return:
Enter IP netmask: IP_netmask
Step 5 Enter Y to enter a default gateway (router) address:
Would you like to enter a default gateway address? [yes]: y
Step 6 Enter the IP address of the default gateway (router), and press Return:
Enter router IP address: IP_address
Step 7 Enter a secret password and press Return:
Enter enable secret password: secret_password
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
!
end
!
Use this configuration? [yes/no]:
Verify that the addresses are correct, enter Y, and press Return. If the addresses are not correct, enter N, press Return, and begin again at Step 2.
The "Configuring the Switch for Telnet" section describes how to set a password to protect the switch against unauthorized Telnet access.
The "Recovering from a Lost or Forgotten Password" section describes how to access the switch without entering the password.
