Figure 11: Airflow Through the Chassis
•
If you are mounting the services gateway on a rack or cabinet along with other
equipment, ensure that the exhaust from other equipment does not blow into the
intake vents of the chassis.
•
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the services gateway as indicated in
Table 17 on page 26.
Table 17 on page 26 provides information about the clearance requirements for
maintaining optimum airflow and the distancesnecessary to facilitate easy maintenance
of the services gateway.
