Powering on a Switch for the First Time

Procedure

1. Perform the following checks before powering on a switch:
   1. Use a multimeter to check that there is no short-circuit condition between the phase wire (live wire), ground wire, and neutral wire in each power outlet.
   2. 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, see Checking the Power Supply System.
   3. Check that the power switches of the external power supply system and the switch or the power module are both turned off.
   4. Check that the power cables are correctly connected.
2. 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.
3. Connect the DB-9 connector of the console cable to the 9-pin serial port on a maintenance terminal. Then, connect the RJ45 connector of the console cable to the console port on the switch. See Figure 1.
   Figure 1 Console cable connection
   
   

   • After connecting both ends of the console cable, power on the switch. During the startup of the switch, you can choose whether to enter the BootROM menu. The BootROM menu and the procedure to enter it vary depending on software versions. For details, see the upgrade guide for the switch and software version in use.
   • If a switch has a mini USB port, you can also use a mini USB cable to connect the switch to a maintenance terminal.

4. Turn on the external power supply system connected to the switch.
5. Turn on the power switch on the switch or power module.
   

   Skip this step if the switch does not support pluggable power modules or does not have a power switch.

6. After the switch completes its startup, check the indicators on the switch and power modules.

   The SYS indicator on the switch and the STATUS indicators on the fan modules and power modules should be steady green. For details about indicator states and meanings, see Appendix A Indicators.

   

   After startup, the command line interface (CLI) is displayed, through which you can configure the switch. For details about how to configure the switch and the configuration commands used, see the CLI-based Configuration Guide for the switch.
