Juniper CTP151 Platform, Hardware Manual, Page: 29 / 104

Follow these environmental guidelines:
•
The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the
efficiency of the device cooling system.
•
Maintain ambient airflow for normal operation of the device. If the airflow is blocked or restricted, or if
the intake air is too warm, the device might overheat, leading to the device temperature monitor shutting
down the device to protect the hardware components.
Table 6 on page 20 provides the required environmental conditions for normal operation of the device.
