1 7 Rack latches
If your server is installed in a rack, you can use the rack latches to help you slide the server out of the rack.
You also can use the rack latches and screws to secure the server in the rack so that the server cannot slide
out, especially in vibration-prone areas. For more information, refer to the Rack Installation Guide that comes
with your rail kit.
2 2.5-inch hot-swap drive bays
The number of the installed drives in your server varies by model. When you install drives, follow the order of
the drive bay numbers.
The EMI integrity and cooling of the server are protected by having all drive bays occupied. The vacant drive
bays must be occupied by drive fillers.
