TCX1000-RDM20 AC Power Supply Description

 

The AC power supplies in the TCX1000-RDM20 (see Figure 1) are hot-removable and hot-insertable field-replaceable units (FRUs) that you can install without powering off the TCX1000-RDM20 or disrupting the functioning of the TCX1000-RDM20. The TCX1000-RDM20 has two power supplies. Both power supplies are initially installed at the factory. See Figure 2 for the power numbering scheme.

Each of the 650-W power supplies has a single AC input. The power supply provides 12-VDC output with a standby voltage of 12 VDC. A TCX1000-RDM20 has twice the number of power supplies needed to power all of the components in the device, which is known as 1+1 redundancy. When the TCX1000-RDM20 has both power supplies installed and connected to power, the device has full power redundancy. If a power supply fails or is removed, the other power supply provides power for the full load without interruption.

The fan in the power supply provides front-to-back airflow, which is also known as airflow out (AFO).

Caution

To avoid electrical injury, carefully follow instructions in Connecting AC Power to a TCX1000-RDM20 , Installing a Power Supply in a TCX1000-RDM20, and Removing a Power Supply from a TCX1000-RDM20.
