Important Points to Remember for Installing a DC Power
Supply
When using DC power supply, peel off the DC electrical label and place it on the main regulatory label
found on the bottom of the S5000 chassis. Position this label over the AC electrical ratings within the
dashed outline.
The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the
PSU or the S5000 chassis.
The S5000 supports AC and DC power supplies with two air-flow directions (I/O to Utility and Utility
to I/O). The S5000 does not support mixing PSU types, that is, you cannot replace an AC PSU with a
DC PSU and an AC-R PSU with a DC-R PSU. The fan airflow direction for both the PSUs must be the
same.
For DC PSUs, the power status LED is on the upper-left corner.
A DC PSU must be properly grounded. The system does not work when plugged into the wrong
power source polarity.
To view the log messages, use the show logging command. For more information, refer to the
System Logs chapters of the
