NOTE: Typically, the first Fibre Channel HBA that is initialized during the POST is the Fibre Channel HBA on the lower slot number. However, because this can change depending on your server architecture, always check your specific system architecture first. Connect the second Fibre Channel HBA that is initialized during the POST to the passive Fibre Channel Interconnect Switch (that is, the Fibre Channel SAN switch that is connected to the MSA1500 passive controller-in other words, the controller on the left as you look at the MSA1500 from the front).

However, because this can change depending on your server architecture, always check your specific system architecture first. Connecting the power cords To protect your system from power-failure-related downtime, each MSA ships standard with a redundant power supply. Depending how you connect the power supplies to your power source, you can eliminate downtime caused by power-related failures. When connecting the power cords, use the power cords shipped with the MSA. After power is supplied to the MSA, the power supply automatically senses the input voltage and the LED behind the power switch illuminates as solid amber.

Connecting the power cords
To protect your system from power-failure-related downtime, each MSA ships standard with a
redundant power supply. Depending how you connect the power supplies to your power source,
you can eliminate downtime caused by power-related failures.
When connecting the power cords, use the power cords shipped with the MSA. After power is
supplied to the MSA, the power supply automatically senses the input voltage and the LED behind
the power switch illuminates as solid amber.
