Replacing a Switch

Procedure

1. Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that it is in close contact with your wrist and grounded properly.
2. Confirm that the names, models, and specifications of the new and original switches are the same. If a mismatch is found, contact technical support as soon as possible.
3. Record the IDs of slots where modules are installed and cable connections on ports of the original switch.
4. Back up configuration data of the original switch as follows: Run the save command to save configuration data into a configuration file on the storage medium, and copy the configuration file to a maintenance terminal.
5. Power off the original switch.
   

   The switch is successfully powered off when all indicators are off.

6. Remove all cables and pluggable modules from the switch.
7. Remove M6 screws from the mounting brackets and remove the switch from the cabinet (skip this step if the switch is installed on the desktop).
   

   When removing screws from the mounting brackets, hold the bottom of the switch to prevent it from falling down to cause personnel injury or damage to other devices.

8. Remove mounting brackets from the original switch and install the mounting brackets on the new switch.
9. Install the new switch in the same position as the original switch and secure it with M6 screws.
10. Install the original modules and cables according to the recorded information.
11. Power on the new switch and observe indicators on it. Normally, the SYS indicator on the switch and the STATUS indicators on the power module and fan module are steady green.
12. Log in to the new switch and check whether the switch is working properly.

    Run the display device command to check the running status of the new switch.
