Explanation
A problem with output overload has been reported
by the uninterruptible power supply 2145 UPS-1U. The Overload Indicator
on the 2145 UPS-1U front panel is illuminated red.
User Response
- Ensure that only one 2145 is receiving power from the 2145 UPS-1U.
Also ensure that no other devices are connected to the 2145 UPS-1U.
- Disconnect the 2145 from the 2145 UPS-1U. If the Overload Indicator
is still illuminated, on the disconnected 2145 replace the 2145 UPS-1U.
- If the Overload Indicator is now off, and the node is a 2145-CG8
or 2145-CF8, on the disconnected 2145, with all outputs disconnected,
determine whether it is one of the two power supplies or the power
cable assembly that must be replaced. Plug just one power cable into
the left hand power supply and start the node and see whether the
error is reported. Then shut down the node and connect the other power
cable into the left hand power supply and start the node and see whether
the error is repeated. Then repeat the two tests for the right hand
power supply. If the error is repeated for both cables on one power
supply but not the other, replace the power supply that showed the
error; otherwise, replace the power cable assembly.
