2. Remove the failed expander.

a) Label all cables to ensure proper recabling later, then remove the cables from the expander.

b) Pinch the controller handle release clip to unlatch the controller handle.

c) Grasp the failed expander by the handle and use a firm, steady pressure to pull the expander out of the chassis bay.

Use two hands to support the expander during removal, but keep the expander tray level, with one hand supporting

the expander platform from underneath to prevent it from falling forward.

Important:

To avoid electrostatic damage, place array components on a grounded anti-static mat. Use an ESD wrist strap

during removal and replacement.

3. Install the replacement expander.

a) Slide the replacement expander into the chassis bay until the handle latches into place.

Do not force the expander. If it does not slide in easily, remove it and try again.

b) Reattach the cables (use the labeling from step 2a as a guide).

4. 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.

5. Return the failed expander as directed on the RMA work order.
