Optical Ila Environmental Requirements And Specifications - Juniper PTX3000 Hardware Manual

Optical ILA Environmental Requirements and Specifications

The optical ILA must be installed in a rack or cabinet. 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 optical ILA cooling system.
Maintain ambient airflow for normal optical ILA operation. If the airflow is blocked or restricted, or if
the intake air is too warm, the chassis might overheat, leading to the optical ILA temperature monitor
shutting down the device to protect the hardware components.
Table 14 on page 44 provides the required environmental conditions for normal operation of the optical
ILA .

NOTE: Install the optical ILA 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 41° F (5° C) through
104 F (40° C). Short-term temperature is 23° F (–5° C) through 131 F
(55° C)
Nonoperating storage temperature in shipping container: –40°F (40° C)
through 158° F (70° C).
Designed to comply with Zone 4 earthquake requirements per NEBS
GR-63-CORE, Issue 3.
