WSI2 board
indicators (LEDs)
and switch
The diagram below shows two indicators and a switch at the left. These are
the WSI2 board indicators. These indicators are directly visible with the
chassis front cover in place. The indicators are described as follows:
• Transaction error (red LED)
Indicates that a data parity error or bus error was encountered during
normal operation on the backplane module bus.
• WSCPU running (yellow LED)
When on indicates that the coprocessor software (HP-UX) is up and
running.
• Shutdown Switch
The switch can be used to force a coprocessor (HP-UX) shutdown. It is
recommended that the keyboard method (as documented in the
A

M
System Administration
manual) be used whenever possible.
The positions of this switch are defined as follows:
To the left = Shutdown
To the right = Normal
• The remainder of the diagram shows the connectors and indicators on
the coprocessor daughter board free edge. They are defined in a later
diagram.
