Removing And Reinstalling The Rack Handles - Lenovo ThinkServer RD440 User Manual And Hardware Maintenance Manual

Notes:
• Use only parts provided by Lenovo.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
The EMI integrity and cooling of the server are protected by having all drive bays and PCI card slots covered
or occupied. When you install an internal drive or a PCI card, save the EMI shield or dummy tray from the
drive bay or save the PCI card slot bracket in case you later remove the device.
Attention: An unoccupied drive bay or PCI card slot without a cover, shield, dummy tray, filler, or any
other protection might impact the EMI integrity and cooling of the server, which might result in overheating
or component damage.
