Table 3: Total Available Power with Four PSMsĮvery module for the GigaVUE-HC3 has a rated maximum Watts. Table 3: Total Available Power with Four PSMs shows the calculation for the total available power, where a PSM is present in all slots. Table 2: Total Available Power with Three PSMs Table 2: Total Available Power with Three PSMs shows the calculation for total available power, where there are three PSMs and one empty slot. Power management adds the eligible rated Watts to the available power and subtracts any removed, failed, or no input voltage power supply module from the available power. The maximum Watts is the available power for each AC or DC power supply module.įor a PSM to be included in available power, the PSM must be plugged in and have a status of on. Table 1: Input Voltage and Maximum Watts lists the PSMs with their input voltage and maximum rated Watts. Total redundant power-the total redundant power in the systemĮvery PSM has maximum rated Watts. Power redundant-the status of yes/no of whether or not the system currently has redundant power Power available-the power remaining and available after power has been allocated Power allocated-the power allocated to the modules by power management Total power-the total power available in the system, based on the PSMsīase power-the power needed for the control card and base system The following attributes for power computation are defined as follows: Note: Power management does not control power up/down of the control card. When a module is powered down by power management, the operational status of the module is shown as nopower in the output of the show cards command, which indicates that it was powered down by power management. When additional power is added, power management powers up the modules present in the higher priority slots before it powers up the modules in the lower priority slots. If the needed power is more than the available power, only the modules in the higher priority slots are powered up.įor example, when the available power falls below the needed power due to a PSM failing or being unplugged or removed, the module in the lowest priority slot is powered down first. The modules are powered up based on the available power. The modules present and configured in the chassis are used to calculate needed power. Available power is the total power available to power up the modules in the GigaVUE-HC3.
When all PSMs are plugged in and are up (LED status light is green), their power is pooled and used to calculate the available power. A mix of AC and DC power supply modules is not recommended. Two or four PSMs are recommended for 1+1 redundancy (two PSMs) or 2+2 redundancy (four PSMs). The power supply modules can be either AC or DC. Slot 4 defaults to the lowest priority of 4.Ī GigaVUE-HC3 chassis can have up to four PSMs. Slot 1 defaults to the highest priority of 1. It determines the priority of the modules to power up or down based on the total PSMs present.Īll four of the slots on the GigaVUE-HC3 are assigned a power priority. Power management controls power up/down of the modules in the GigaVUE-HC3 node through software.
