Powering on the Switch for the First Time

Powering on the Switch for the First Time

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Multimeter
  • Console cable


  1. Check the switch before powering it on.
    1. Check that the power modules installed on the switch are turned off. (Skip this step if the power modules do not have power switches.)
    2. Use a multimeter to check that there is no short-circuit condition between the phase wire (also called the live wire), earth wire, and neutral wire.
    3. Use the multimeter to check that the input voltage provided by the external power supply system is within the operating voltage range for the switch. For the operating voltage range required by the CE8800&7800&6800&5800 series switches, see Switches Overview.
  2. Check that the power cables are correctly connected.
  3. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  4. Connect the console cable.

    Connect the DB-9 connector (with holes) of the console cable to the 9-pin serial port on the maintenance terminal, and connect the RJ45 connector of the console cable to the console port on the switch. See Figure 10-1.

    Figure 10-1 Console cable connection

    After connecting the switch to the maintenance terminal using the console cable, power on the switch. When the switch is starting, you can choose whether to enter the BootROM menu. The BootROM menu and the procedure for entering the BootROM menu vary according to software versions. For details about the BootROM menu, see the upgrade guide for the specific product and software version.

    The CE6850-48S6Q-HI, CE6850U-48S6Q-HI, CE6850-48T6Q-HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-24S2Q-HI, CE6875-48S4CQ-EI, CE8850-64CQ-EI, CE8860-4C-EI, CE8861-4C-EI, and CE8868-4C-EI also support first login through the Mini USB port. For details on the login method, see the Configuration Guide of the product.

  5. Turn on the power modules. (Skip this step if the power modules do not have power switches.)
  6. Check the switch after powering it on.

    Check the following items after powering on the switch:

    • Whether the sound of fans can be heard and air is exhausted from the air vent. (If the switch uses front-to-back airflow, air is exhausted from the air vents at the port side. If the switch uses back-to-front airflow, air is exhausted from the air vents on the fan modules at the power supply side.)

    • Whether the indicators on the switch, power modules, and fan modules are in normal state. Normally, the SYS indicator on the switch and the STATUS indicators on the fan modules and power modules are steady green. For details about indicator states and meanings, see Appendix A Indicators.

    After the switch is powered on and completes the startup, the command line interface (CLI) is displayed. You can configure the switch on the CLI. For details about the configurations supported and commands used, see the Configuration Guide of the switch.

Follow-up Procedure

Powering off the switch will interrupt all the services on the switch. Exercise caution when you perform this operation.

To power off the switch, perform the following steps:

  1. Turn off the power modules. (Skip this step if the power modules do not have power switches.)
  2. Turn off the external power supply system connected to the switch.
  3. Check that the switch and all its modules are powered off.
