Procedure
Step 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), earth 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 3.4 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.
Step 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.
Step 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 10-1.
