Remove a tray from the enclosure

Use this information to remove a DWC tray from the enclosure.

About this task

Attention

For safety reasons, when removing a tray or a PCS, it is highly recommended to use the Genie® Lift™ GL™-8 due to the server’s weight. Lenovo offers the lift with add on fixtures Genie Lift GL-8 Option Kit and GL-8 Kit for N1380 and SC Systems. If no lift tool is available on-site, customers must move the machine to an accessible, powered area before the trained technician arrives and handles reinstallation. Lenovo strongly advises configuring a complete solution for N1380 and SC-Systems with the lift tool and its add-on features via non-racked items.

Important

Mandatory tools for tray removal and installation.

• Lift tool assembly

  • Genie GL-8 lift tool installed with the lift tool fixture. The foot-release brake should also be attached to the lift tool.

  • For assembling instructions, see Setting up the lift tool assembly

• Rotate fixture cart assembly

  • Rotate fixture installed on the customized cart.

  • For assembling instructions, see Setting up the rotate fixture cart assembly

• For mandatory tools ordering information, see ThinkSystem server options.

    CAUTION

    Protective gloves should be worn for this procedure.

    The tray might be very hot. Wait several minutes to let the tray cool before removing the tray cover.

    
    
    
16. Once the DWC tray has been serviced, place the tray back into the original position as soon as possible.
    Attention

    • To maintain proper system cooling, do not operate the enclosure without a DWC tray or tray bay filler installed in each tray bay. For more information, see Install a tray in the enclosure.

    • When you remove the DWC tray, note the tray bay number. Reinstalling a DWC tray into a different tray bay from the one it was removed from can have unintended consequences. Some configuration information and update options are established according to tray bay number. If you reinstall the DWC tray into a different tray bay, you might have to reconfigure the DWC tray.
