Power-On Diagnostics

All VS1000 units include autoswitching power supplies.
You may need to select the appropriate power cable for
your location, but the VS1000 automatically senses and
switches to the correct line voltage and cycle frequency.
The VS1100 expansion unit draws its power from the
host VS1000 base unit and does not contain a power
supply or cooling fan.
After you have connected the VS1000 to the network,
and the VS1100 to the VS1000, connect the power cord
to the VS1000 and switch the VS1000 on. Then use the
following information to determine if your VS1000/
VS1100 units are working correctly.
1. If the LEDs for Ports 1 through 16 flash during
power up, the VS1000/VS1100 hardware is working
properly.
2. If using the 10Base-T connection and the polarity is
correct, the lower LED remains on.
Note: After the power-up tests, the VS1000 waits for the
server PC to download the VS-Link software. The
Port 1 LED blinks while the VS1000 is waiting
and goes out when the server initiates normal
program activity.
3. If the LEDs do not display an error condition, go to
the Installation and Configuration Guide for
instructions on installing and configuring VS-Link
for your operating system.
