10 Installing the Hardware
Leakage Current (High Touch Current) in AC-powered systems with more
than 3+1 power supplies. The power cord plugs must be secured to the building
outlets by the qualified chassis installer or a qualified electrician
.
WARNING: The C300 operates in either of two voltage ranges. Each range
supports a different power supply configuration. 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.
Installing DC Power Supplies
• The C150 requires at least one DC PEM for operation, but Dell Force10
recommends a one-plus-one redundancy configuration. Those DC PEMs are
inserted in slots 0 and 2.
• The C300 requires at least one DC PEM for operation, but Dell Force10
recommends a one-plus-one redundancy configuration. Those DC PEMs are
inserted in slots 0 and 7.
Voltage Frequency Maximum PSU
100 -110 50/60Hz 6 primary + 2 redundant
200 - 240 50/60Hz 3 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 Force10 recommends installing power supplies starting from the
left side, top row of the chassis, leaving no blank slots between units.
4 Plug the AC power cord into the power receptacle in the face of the
power supply.
5 Lower the retaining latch, and tighten it into place.
6 Plug the power cord into an AC power outlet.
