IBM System x3850 X5 Implementation Manual page 77

The x3850 X5 has the following physical specifications:
Width: 440 mm (17.3 in.)
Depth: 712 mm (28.0 in.)
Height: 173 mm (6.8 in.) or 4 rack units (4U)
Minimum configuration: 35.4 kg (78 lb.)

Figure 3-1 shows the x3850 X5.
Figure 3-1 Front view of the x3850 X5 showing eight 2.5-inch SAS drives
In Figure 3-1, two serial-attached SCSI (SAS) backplanes have been installed (at the right of
the server). Each backplane supports four 2.5-inch SAS disks (eight disks in total).
Notice the orange colored bar on each disk drive. This bar denotes that the disks are
hot-swappable. The color coding used throughout the system is orange for hot-swap and blue
for non-hot-swap. Changing a hot-swappable component requires no downtime; changing a
non-hot-swappable component requires that the server is powered off before removing that
component.
Figure 3-2 on page 58 shows the major components inside the server and on the front panel
of the server.
