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 ships without a coverplate for the PS1 bay.

Note

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

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

1. Before handling a power supply, put on the antistatic wrist strap and attach it to the ground receptacle on the front of the SSA.
   Refer to the instructions in the anti-static wrist strap package. See SSA Ground Receptacle for the location of the ground receptacle.

2. Visually verify that the power supply airflow direction agrees with the airflow direction of the installed fan module.
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 is completely inside the bay.
   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 screws that attach the coverplate to the SSA.

   Keep the coverplate in case you need to remove the power supply.

6. Repeat step 2 through step 4 to install the power supply in the right power supply bay.
7. Tighten the captive screws of the power supplies.
