Measure the resistance of the disconnected mainline dc power cable from the ground pin
on one end to the cable ground (green and yellow) on the other end.
The measurement should be 0.1 ohms or less.

Internal Grounding on the 8265
On the 8265
Check that electrical continuity is assured within the chassis, between the chassis and the
installed power supplies via screws and internal connectors.
On the Rack (When the 8265 Is Installed In a Rack)
Check that electrical continuity is assured between the 8265 frame (chassis) and the rack
where the 8265 is installed.
There are two ways to ensure proper grounding of the rack:
1) Grounding is ensured by the screws which secure the 8265 chassis on the rack.
2) Grounding is assured by wire
.1/
connected from the 8265 chassis to the rack.
Note: The ground wire
.1/
is not provided by IBM.
