Caution
Temperature: The operating temperature of the server, when
installed in an equipment rack, must not go below 5 °C or rise
above 35 °C. Extreme fluctuations in temperature can cause a
variety of problems in your server.
Ventilation: The equipment rack must provide sufficient airflow
to the front of the server to maintain proper cooling. It must also
include ventilation sufficient to exhaust the total sum of the Btu's
per hour for the servers installed in the rack. The rack selected
and the ventilation provided must be suitable to the
environment in which the server will be used.
Note: For vertical reference, every three screw holes on the
vertical mounting rail are equal to 1U (1.75 inches).
Figure 35: 1U specifications (in millimeters)
Mounting holes in the vertical mounting rails of equipment racks
are commonly spaced in a 5/8 x 5/8 x 1/2-inch sequence. Per-
form the following steps carefully; brackets must be mounted
with precision to allow room for the next server you install in a
rack.
