Page 13: Power Consumption And Heat Dissipation
Conditions other than worst case would permit increasing the number of COTS per bay without jeopardizing the CO thermal integrity. Due to the chimney effect, ADC recommends you install one heat-dissipating baffle between every COTS. This action would prevent exceeding the rated operating temperature of the COLU units. -
Page 14: Maximum Power Consumption
Monitoring, History and Diagnostics SCP-PLL722-010-04H Maximum Power Consumption Maximum power consumption is the total power that the COLU consumes or draws from its -48 Vdc COTS power source. This parameter is needed when the COLU is located remotely from its serving CO. It determines the battery capacity required to maintain an 8-hour standby battery reserve for emergency situations. -
