Maintain ambient airflow for normal operation. If the airflow is blocked or restricted, or if the intake air
is too warm, the appliance might overheat.
Table 10 on page 23 lists the environmental conditions required for normal operation.
Table 10: Environmental Specifications for SSR120

Clearance Requirements for Hardware Maintenance of SSR120
When planning the site for installing an SSR120, you must allow sufficient clearance around the installed
chassis.
•
For the operating temperature of the SSR120 to be optimal, the airflow around the chassis must be
unrestricted.
•
For service personnel to remove and install hardware components, and to accommodate the interface
and power cable bend radius, there must be adequate space at the front and rear of the appliance. Allow
at least 24 in. (61 cm) of space both at the front and the rear of the appliance.
•
If you are mounting the appliance in a rack with other equipment, or if you are placing it on the desktop
near other equipment, ensure that the exhaust from other equipment does not blow into the intake
vents of the chassis.
