Installing the Power Supplies

If you are installing only one power supply, you must put the power supply in the left power supply bay (labeled PS1). The SSA switch ships without a coverplate for the PS1 bay.

Note

For proper operation, the SSA switch must have a power supply in PS1 whenever the SSA switch is powered up.

To install the power supplies in the SSA switch, follow these steps:

1. Use appropriate antistatic protection when handling power supplies.
2. Visually verify that the power supply airflow direction agrees with the airflow direction of the installed fan module.
   For details, see Power Supply Airflow and Switch Fan Module Airflow.
3. Holding the power supply by the handle and bottom, align the power supply with the left power supply bay (labeled PS1).
4. Slide the power supply forward until it is plugged into the chassis connector and the lock tab clicks to the right.
   Pull on the power supply handle to ensure that the power supply is firmly in place. See Installing a Power Supply.

5. If you are installing a second power supply, remove the coverplate from the right power supply bay by unscrewing the screw that attaches the coverplate to the SSA switch and rotating the coverplate out of its position from right to left before disengaging it from the chassis (see Removing the Power Supply Bay Coverplate). Reinstall the screw after the cover plate is removed.

   Keep the coverplate in case you need to revert to a single power supply configuration. If a power supply is not installed, the coverplate must be in place for proper airflow.

6. Repeat step 2 through step 4 to install the power supply in the right power supply bay.
