Installing a server module
NOTE: Ensure that you remove the server module partitions before installing the M820 server
module. For information about removing the server module partitions, see Dell PowerEdge VRTX
Enclosure Owner’s Manual at dell.com/poweredgemanuals.
1. If you are installing a new server module, remove the plastic cover from the I/O connector(s) and
save for future use.
2. Orient the server module so that the handle is on the left side of the server module.
3. Align the server module with the server module slot and the guide rails on the enclosure.
4. Using both hands, slide the server module into the enclosure until the module release handle
engages and locks the server module in place.
5. If applicable, reinstall the front bezel.
