4. Install the replacement expander.
a) Make sure the release levers are fully extended.
b) Slide the expander into the chassis bay. If it does not slide in easily, remove it and try again.
c) After the expander is in place, return the release levers to their original closed position, and then tighten the
thumbscrews.
d) Reconnect the network cables to the expander (as labeled from step 2).
e) Reconnect the power cables to both power supplies.
5. Verify that the new expander is powered on.
After it is installed, the expander powers on automatically. The LEDs on the expansion shelf light solid green. If the expander
does not power on automatically, contact HPE Support.
Note: The new expander might take up to 15 minutes to appear in the user interface. If the expander takes longer
than 15 minutes to report an Active/Standby state, contact HPE Support for assistance.
6. Return the failed expander as directed on the RMA work order.
