Ptx10003 Environmental Requirements And Specifications - Juniper PTX10003-80C Hardware Manual

PTX10003 Environmental Requirements and Specifications

The PTX10003 must be installed in a rack. It must be housed in a dry, clean, well-ventilated, and
temperature-controlled environment.
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 PTX10003 cooling system.
Maintain ambient airflow for normal PTX10003 operation. If the airflow is blocked or restricted, or if
the intake air is too warm, the chassis might overheat, leading to the PTX10003 temperature monitor
shutting down the router to protect the hardware components.
Table 22 on page 73 provides the required environmental conditions for normal PTX10003 operation.

NOTE: Install the PTX10003 only in restricted access areas, such as dedicated equipment rooms
and equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NFPA 70.
Tolerance
No performance degradation up to 6000 feet (1828.8 meters).
Normal operation ensured in relative humidity range of 5% through 90%,
noncondensing.
Short-term operation ensured in relative humidity range of 5% through 93%,
noncondensing.
NOTE: As defined in NEBS GR-63-CORE, Issue 3, short-term events can
be up to 96 hours in duration but not more than 15 days per year.
Normal operation ensured in temperature range of 32° F (0° C) through
104° F (40° C).
Nonoperating storage temperature in shipping container: –40° F (40° C)
through 158° F (70° C).
Complies with Zone 4 earthquake requirements per NEBS GR-3160-CORE,
Issue 3.
