6.9Redundancy

The power sub-system may have different levels of redundancy depending upon the availability requirements of the system. The Required, Recommended, and Optional items are broken down here. To be redundant each item must be in the hot swap power supply module.

STATUS

Required

The power sub-system shall have redundancy of the main power converters for the power factor correction stage and the main +12V output.

STATUS

Recommended

It is recommended the power sub-system have redundancy for the following items, however, depending upon the system availability requirements, these items may be non-redundant.

It is recommended to have redundancy for the output or’ing devices, fans, AC bridge, output capacitors, -12V converter, and 5VSB converter.

STATUS

Optional

It is optional to have redundancy for the AC EMI filter components, 3.3V output converter, and 5V output converter.

6.10 Hot Swap Requirements

STATUS

Required

The power supply modules shall be hot swappable. Hot swapping a power supply is the process of inserting and extracting a power supply from an operating power system. During this process the output voltages shall remain within the limits specified in Table 20 with the capacitive load specified Table 23. The hot swap test must be conducted when the sub-system is operating under both static and dynamic conditions. The sub-system shall not exceed the maximum inrush current as specified in section 5.8. The power supply can be hot swapped by the following methods:

•AC connecting separately to each module. Up to two power supplies may be on a single AC power source. Extraction: The AC power will be disconnected from the power supply first and then the power supply is extracted from the sub-system. This could occur in standby mode or powered on mode. Insertion: The module is inserted into the cage and then AC power will be connected to the power supply module.

•For power modules with AC docking at the same time as DC. Extraction: The module is extracted from the cage and both AC and DC disconnect at the same time. This could occur in standby or power on mode. No damage or arcing shall occur to the DC or AC contacts which could cause damage. Insertion: The AC and DC connect at the same time as the module is inserted into the cage. No damage to the connector contacts shall occur. The module may power on or come up into standby mode.

Many variations of the above are possible. Supplies need to be compatible with these different variations depending upon the sub-system construction. In general, a failed (off by internal latch or external control) supply
