Operating Power Limits and Ranges
The table below gives operating and power information for the Sun Fire V120 and
Netra 120 servers.
Netra 120 servers.
*
For both servers, the in-rush current decays to the normal operating current in less than
200 milliseconds. The in-rush decaying peaks last for less than 3 milliseconds in each half
cycle.
cycle.
Note –
The figures for the maximum operating current are provided to help you
specify the fusing and cabling you need to deliver power to your equipment.
However, these figures represent “worst-case” scenarios. Such occurrences are
unlikely in a real installation.
