Intel® Server Chassis H2000 Family TPS Power Sub-System Table 29. SMBAlert# Signal Characteristics Signal Type (Active Low) Alert# = High Alert# = Low Logic level low voltage, Isink=4 mA Logic level high voltage, Isink=50 A Sink current, Alert# = low Sink current, Alert# = high Alert# rise and fall time Open collector/drain output from power supply. Pullup to VSB located in system. OK Power Alert to system MIN MAX 0 V 0.4 V 3.46 V 4 mA 50 A 100 s 3.6 Protection circuits Protection circuits inside the power supply shall cause only the power supply's main outputs to shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15sec and a PSON# cycle HIGH for 1sec shall be able to reset the power supply. 3.6.1 Current Limit (OCP) The power supply shall have current limit to prevent the outputs from exceeding the values shown in table below. If the current limits are exceeded the power supply shall shutdown and latch off. The latch will be cleared by toggling the PSON# signal or by an AC power interruption. The power supply shall not be damaged from repeated power cycling in this condition. 12VSB will be auto-recovered after removing OCP limit. Table 30. Over Current Protection Output VOLTAGE PSU SKU +12V +12VSTB Input voltage range 90 - 264VAC 90 - 264VAC OVER CURRENT LIMITS 1200W 1600W 140A min; 170A max 180A min; 200A max 2.5A min; 3A max 2.5A min; 3A max 3.6.2 Over Voltage Protection (OVP) The power supply over voltage protection shall be locally sensed. The power supply shall shutdown and latch off after an over voltage condition occurs. This latch shall be cleared by toggling the PSON# signal or by an AC power interruption. The values are measured at the output of the power supply's connectors. The voltage shall never exceed the maximum levels when measured at the power connectors of the power supply connector during any single point of fail. The voltage shall never trip any lower than the minimum levels when measured at the power connector. 12VSBwill be auto-recovered after removing OVP limit. Table 31.
