The DPM5500 system is designed to fit in a standard 19 inch
wide rack. It is important to the chassis installation to locate
the hole pattern in the rack rails (see
figure 2
).

ARNING
:
If the rack is empty at the time of
installation, do NOT install the DPM5500
chassis too high in the rack. The weight of
the chassis may cause the rack to become
“top heavy” and unstable if installed in the
top of an empty rack.
