General Specifications Intel® Server Boards SE7320SP2 and SE7525GP2 Table 104. Turn On / Off Timing Item Tsb_on_delay T ac_on_delay Tvout_holdup Tpwok_holdup Tpson_on_delay T pson_pwok Tpwok_on T pwok_off Tpwok_low Tsb_vout T5vsb_holdup Description Delay from AC being applied to 5VSB being within regulation. Delay from AC being applied to all output voltages being within regulation. Time all output voltages stay within regulation after loss of AC. Delay from loss of AC to de-assertion of PWOK Delay from PSON# active to output voltages within regulation limits. Delay from PSON# deactive to PWOK being de-asserted. Delay from output voltages within regulation limits to PWOK asserted at turn on. Delay from PWOK de-asserted to output voltages (3.3V, 5V, 12V, 12V) dropping out of regulation limits. Duration of PWOK being in the de-asserted state during an off/on cycle using AC or the PSON signal. Delay from 5 V SB being in regulation to O/Ps being in regulation at AC turn on. Time the 5 VSB output voltage stays within regulation after AC lost.
