AC Power Cord

The AC power sockets are located on the rear of the chassis. Contact Celestica if you want to use other types of power cords.

CAUTION: For products with multiple power cords, all power cords must be disconnected to completely remove power from the system.
CAUTION: Not all power cords have the same current ratings. Do not use the power cord provided with your equipment for any other products or use. Do not use household extension cords with your product.
CAUTION: This product is designed to work with power systems having a grounded neutral (grounded return for DC-powered products). To reduce the risk of electric shock, do not plug products into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

Important:

This product supports the use of Titanium-rated PSUs and Platinum-rated PSUs, but does not support mixed use.

Only use PSUs with identical part numbers. Two Titanium-rated PSUs with different part numbers is not supported.

Case 1: For a whole system initial power up, if the system is powered up with non-matching PSUs, the system will not function (allow data I/O) until a valid configuration is installed.

Case 2: If a PSU is replaced with a non-matching PSU while the system is functioning, the system will power off the newly inserted PSU and trigger an alarm mix log and the enclosure fault LED.

Case 3: All PSUs are of the same certified rating (Titanium or Platinum) but the part numbers do not match.
