PSU Installation Guidelines
•
The C9010 requires the use of at least one power supply for normal operation. Dell Networking
recommends using additional power supplies for redundancy depending on the maximum system
power that is required and the local power grid voltage (100~120Vac/200~240Vac).
•
C9010 power supplies do not support a combination of power grid types. For example, all PSUs in a
C9010 should be powered either by 200~240Vac or 100~120Vac, but not both. Do not mix utility
input.
•
To protect against high-voltage shock, install a power supply blank in all unused power supply slots.
•
Connect the AC power supply to the appropriate branch circuit protection as defined by your local
electrical codes.
•
Verify that the remote power source complies with the system input power specifications.
WARNING: Use only the AC power cord supplied with the AC power supply. Do not supply power
to your system until you install the power supplies, fan tray, route process modules (RPMs) and
linecards.
WARNING: The C9010 relies on the building's installation for short-circuit (overcurrent)
protection. Dell Networking recommends using a fuse or circuit breaker of 120 VAC, 20 A U.S.
(240 VAC, 20 A international) for AC input on each power supply to ensure its maximum power
capacity.
WARNING: The C9010 does not have a main disconnect device. You must provide a suitable
disconnecting device in the building installation. Ensure you locate and install the device near the
equipment and that it is easily accessible.
WARNING: The C9010 operates in either of two voltage ranges. The following lists the different
power supply configuration the C9010 supports. As a safety precaution, do not install more than
the recommended maximum number of PSUs, as this causes high leakage current. Install blank
panels in all unused PSU slots.
PSU Installation Procedure
1.
Verify that the PSU switch is in the OFF (down) position.
2.
Slide the first power supply into the left-most power supply slot (PSU 0) until the latch (item 1 in
Figure 22) snaps in place. Refer to
3.
Plug an AC power cord into the front of the power supply.
4.
Plug the power cord into an AC power outlet.
5.
Repeat Steps 1 to 4 to install additional AC power supplies of the same wattage. Install each
additional power supply in the left-most available PSU slot; for example, install the second power
supply in PSU slot 1, the third power supply in PSU slot 2, and the fourth power supply in PSU slot 3.
6.
Install a blank to cover any open PSU slot.
