WD SENTINEL DS5100/DS6100
ADMINISTRATOR AND MAINTENANCE GUIDE
Adding a Boot Drive
The WD Sentinel server comes with either one (DS5100) or two (DS6100) 2.5-inch boot
drive pre-loaded with Windows Server 2012 R2 Essentials and specialized hardware
services and drivers. The pre-loaded boot drive(s) provides the ability to keep the OS
running from the boot drive while redeploying or changing applications and folders running
on the large capacity data drives.
The boot drive in the WD Sentinel DS5100 server are “cold swappable.” This means that the
WD Sentinel server must be shut down prior to adding a boot drive. To shut down your WD
Sentinel server, follow the steps outline in “Shutting Down and Rebooting the Server” on
page 40.
What you’ll Need:
Phillips screwdriver
Flat-head screwdriver
Boot Drive kit
