3-4 Hardware Installation
Providing Power to the SwitcHub
1. Power on the hub by plugging the power cord into the power socket at the
rear of the SwitcHub, and the other end into a power outlet.
2. Check the LED marked Power on the front panel to see if it is on. The unit
will automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
3. The SwitcHub performs a self-diagnostic test upon power on. (Note that this
test takes about 50 seconds to complete.) For details about the system self-
diagnostic test, refer to the following section.
Diagnostic Tests
Upon Power On
Upon power on, the system performs an internal self-diagnostic test of major
hub components. If any component fails during the test, the hub will try to
complete the diagnostic procedure. Otherwise, the system will hang. For
related information, refer to Diagnostics Display Mode in Chapter 2.
The components to be tested include:
System ROM
System EEPROM
Ports 1 - 2
During Normal Operation
You can use the Configure button any time you want to perform a diagnostic
test. When testing begins, the system leaves normal operation. If no problem
is encountered by the diagnostic test, the system automatically returns to
normal operation.
