20 Installation VH-8TX1UM/VH-8TX1MF

Powering the Switch

To supply power to the switch, connect the power cord to the switch and

to a grounded three-prong wall outlet (Figure 2-3). See Appendix A,

“Technical Specifications” on page 25 for more information regarding

specific international power cord requirements.

Figure 2-3. Connecting the Power Cord

The Power LED lights green (see Figure 1-1). If it does not, check to make

sure that the power cable is plugged in correctly and that the power

source is good.

When power is applied, the switch conducts a series of hardware and

software tests to verify operation. If a terminal or computer is connected

to the console port, the results of the tests are displayed on the screen. If

you want to display the results of the tests after the switch has been

turned on, turn the power to the switch off then back on.

The switch performs two basic types of tests at power-up. During this

time, all the LEDs light in sequence. These tests are:

• Serial port

The serial console port test is the first test. If the switch fails, no

further tests are performed and the console displays no information.

• Memory

Memory tests on the CPU RAM are performed after the serial port

test. No results are displayed on the console.

After these tests are performed, the system initialization screen provides

the option of starting the operational software of the switch or performing

an XMODEM download to upgrade system firmware. When the

operational software is started, the system is functional and the user

interface is ready to receive commands at the console.
