Installing the Hardware 9
WARNING: Use only the AC power cord supplied with the AC power supply.
Do not supply power to your system until the power supplies and fan tray are
installed, and RPMs and line cards have been installed.
WARNING: This product relies on the building's installation for short-circuit
(overcurrent) protection. Ensure that a fuse or circuit breaker no larger than
120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase
conductors (all current-carrying conductors).
WARNING: The C300 does not have a main disconnect device installed. It is
the responsibility of the installer to provide a suitable disconnecting device in
the building installation and ensure that it is located/installed near the
equipment and is easily accessible.
WARNING: The C300 and C150 operates in either of two voltage ranges. The
different power supply configuration supported is listed in the table below. As
a safety precaution, do not install more than the recommended maximum
number of PSUs (given by the table below), as this causes high leakage
current. Install blank panels in all unused PSU slots.
Voltage Frequency Maximum PSUs
C150 100-120 50/60Hz 5 primary + 1 redundant
200-240 50/60Hz 5 primary + 1 redundant
C300 100-120 50/60Hz 7 primary + 1 redundant
200-240 50/60Hz 7 primary + 1 redundant
Step Task
1 Verify the switch is in the OFF (left) position.
2 Secure the retaining latch in the unlatched position by tightening the
screw into the threaded hole.
3 Slide the power supply into the top left-most power supply slot.
Dell Networking recommends installing power supplies starting from
the left side, top row of the chassis, leaving no blank slots between units.
4 Lower the retaining latch, and tighten it into place.
5 Plug the AC power cord into the power receptacle in the face of the
power supply.
6 Plug the power cord into an AC power outlet.
