Server Installations and Upgrades—NSW1U Network Server
With AC power, if the server power cord is plugged into an outlet that is part of the rack, then you
must provide proper grounding for the rack itself. If the server power cord is plugged into a wall
outlet, then the safety ground conductor in the power cord provides proper grounding only for the
server. You must provide additional, proper grounding for the rack and other devices installed in it.
AC Overcurrent protection: The server is designed for an AC line voltage source with up to 20
amperes of overcurrent protection per cord feed. If the power system for the equipment rack is
installed on a branch circuit with more than 20 amperes of protection, you must provide supplemental
protection for the server. The overall current rating of a server configured with two power supplies is
less than 4 amperes.
Caution: Temperature: The operating temperature of the server, when installed in an
equipment rack, must not go below 5° C (41° F) or rise above 35° C (95° F). Extreme
fluctuations in temperature can cause a variety of problems in your server.
Ventilation: The equipment rack must provide sufficient airflow to the front of the server to maintain
proper cooling. It must also include ventilation sufficient to exhaust a maximum of 1200 BTU per hour
for a fully loaded Kontron IP Network Server NSW1U system.
It is important to note that this measurement is the maximum, and a minimum or typical system
could be much less. You may want to calculate the BTU/hr measurement more accurately for your
configuration. An extra 500 BTU/hr over many systems would translate into a large error calculating
air conditioning capacity.
