Turning On Your VES-1012
This chapter discusses the fans and LEDs of the VES-1012 after you turn it on.
5.1 Introduction
Before turning on your VES-1012, make sure you:
•
Have attached a computer to the VES-1012 serial port as explained previously.
•
Can see the status LEDs on the front panel while you view the VT100 terminal emulator.
Push the power switch (located at the back of the VES-1012) to the ON position. The VES-1012 will
automatically run a self-test that takes approximately 20 seconds. The SYS LED will remain on if your VES-
1012 has started normally.
If the SYS LED does not turn on then recheck your connections or refer to the Hardware
Troubleshooting chapter.
Make sure you can feel and/or hear the fans working — working fans emit a low buzz and blow air. The fans are
located on the VES-1012 as shown next. Refer to the
Hardware Troubleshooting chapter to test the fans if they
are not working.
See the next section to interpret the operational status of your VES-1012.
