CAUTION
If you remove a power supply, it is imperative to wait at least
15 seconds before reinserting it. The delay gives the power
supply’s inrush protection circuit time to reset itself. If the
circuit does not have time to reset, the supply draws a larger
than normal inrush current and may trip main circuit breakers
or UPS breakers.

NOTE
The keyboard and mouse ports are interchangeable and at boot
time the I/O Riser board automatically detects which device is
connected to the port. The I/O Riser board, located on the I/O
baseboard behind the rear panel connectors, contains the
electronic circuitry to support all of its connections.
