Keep the coverplate in the event 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 air flow.
6. Repeat steps 2–3 to install the power supply in the right power supply bay.

Powering Up the SSA Switch

To connect the SSA switch to the power sources:
1. Plug a power cord into each power supply's AC power receptacle.
2. Plug the cord into a dedicated grounded AC outlet.
In the case of a two power supply configuration, to take advantage of redundancy capabilities,
plug each power cord into a separate dedicated AC outlet.
The system PWR LED, located on the switch I/O port panel, turns ON (green) and the CPU LED
turns red until the SSA switch completes its initialization. See
and CPU LED locations. It takes under 30 seconds for the SSA switch to boot up.
When the initialization process is successful, the CPU LED turns green. If the CPU LED does not
turn green, refer to
Figure 2-10 on page 2-13). Reinstall the screw once the cover plate is removed.
