Panel Plate and LEDs
Unlike most XIO boards, the TPU XIO panel plate has no ports. It contains three round
LEDs. During normal operation, these LEDs illuminate green.
• 2.5 PWR: indicates that 2.5 voltage is supplied to the board.
• 3.3 PWR: indicates that 3.3 voltage is supplied to the board.
• LINK UP LED: indicates that communications have been established with the
system.
If a problem occurs with power or communications to the board, the LEDs illuminate
amber.

Troubleshooting Suggestion
If any LED fails to illuminate, ensure that the correct software is installed and configured;
refer to “Software Installation and Configuration” on page 4. If any LED still does not
illuminate, contact your SGI authorized service provider.
