2. Inspect for Physical Damage
Carefully examine the switch for any signs of physical damage during shipping. If you notice any issues, contact Cisco support immediately.

Prerequisites and Preparation

1. Environmental Requirements
Before installing the Cisco 9300 switch, make sure the environment meets the following criteria:
Température: 32°F to 104°F (0°C to 40°C).
Humidité: 5% to 95% non-condensing.
Airflow: Ensure proper ventilation for adequate cooling.
2. Tools Required
Ensure you have the following tools ready for installation:
- Phillips screwdriver
- ESD wrist strap
- Rack-mount kit

Installing the Cisco 9300 on a Rack

The Cisco Catalyst 9300 can be installed in a standard 19-inch equipment rack using the included rack-mount brackets. Here are the steps for rack installation:

1. Attach the Rack-Mount Brackets
- Use the screws provided in the rack-mount kit to secure the brackets to the sides of the switch.
- Ensure the brackets are firmly attached and properly aligned with the rack holes.
2. Mount the Switch in the Rack
- Lift the switch and carefully position it in the desired rack space.
- Align the brackets with the rack's mounting holes and secure the switch using the screws.
3. Connect Grounding Wire
- Locate the ground lug on the back of the switch and attach a grounding wire for safety.
- Ensure the wire is properly connected to a verified earth ground.

Powering On the Cisco 9300

Once the switch is securely mounted, you can proceed with powering it on.

1. Connect Power Cables
- Plug the AC power cord into the switch's power supply unit (PSU).
- Connect the other end of the power cord to a power outlet or PDU (Power Distribution Unit).
2. Power On the Switch
- The switch will begin to boot up automatically after being connected to power.
- Observe the LED indicators on the front panel to confirm the switch is powering up correctly.
3. Verify POST (Power-On Self-Test)
- During bootup, the switch performs a POST to check hardware functionality.
- Ensure all system LEDs display a solid green or blinking green status, indicating a successful POST.

Connecting to the Console Port

To configure the switch, you'll need to establish a console connection. Here’s how:

1. Connect Console Cable
- Use the provided RJ-45 console cable to connect the console port on the switch to your computer’s serial port.
- If your computer doesn’t have a serial port, use a USB-to-serial adapter.
2. Open Terminal Software
- Open a terminal emulator such as PuTTY, Tera Term, or HyperTerminal.
- Configure the terminal with the following settings:
Baud Rate: 9600
Data Bits: 8
Stop Bits: 1
Parity: None
Flow Control: None
3. Access the CLI (Command-Line Interface)
- Once connected, press "Enter" to access the switch's CLI.
- You should see the command prompt, indicating a successful connection.

Initial Configuration of Cisco 9300

Now that the console connection is established, you can configure the switch. Begin with basic setup commands.

1. Enter Global Configuration Mode
- At the command prompt, type:

 enable

 configure terminal

2. Set Hostname
- Assign a hostname for the switch:

hostname SwitchName

3. Configure Management Interface
- Assign an IP address to the management interface:

 interface vlan1

 ip address 192.168.1.1 255.255.255.0

 no shutdown

4. Set Enable Secret Password
- For security, configure a password for privileged EXEC mode:

enable secret password

Stacking Cisco 9300 Switches

If you are deploying multiple Cisco 9300 switches, you can stack them for easier management and redundancy.

1. Connect StackWise Cables
- Use the StackWise-480 cables to connect the StackWise ports between switches.
- Ensure that the StackWise cables form a loop for redundancy.
2. Power On the Stack
- Power on all switches in the stack configuration.
- The switches will automatically elect a Stack Master based on configuration.
3. Verify Stack Configuration
- Once the switches are up, use the following command to verify the stack status:
 show switch
- Ensure all switches are properly detected in the stack.
