When logging in to a CE series switch for the first time, you need to use a serial cable to connect to the switch. The CE6850HI, CE6855-48T6Q-HI, and CE6850U-HI switches also support the mini USB port. You can use a mini USB cable to connect to the switch for login for the first time.

How to log in to the device on AR routers for the first time through a console port
When you log in to the device through the console port, you need to install the terminal access software on the local PC (such as SecureCRT software) and set parameters of the terminal simulation software. After the login succeeds, you can configure the following parameters based on the requirements:
- Set the system date, time and time zone.
