TCX1000-RDM20 Cabinet Requirements on page 31
The TCX1000-RDM20 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 TCX1000-RDM20 cooling system.
Maintain ambient airflow for normal TCX1000-RDM20 operation. If the airflow is
blocked or restricted, or if the intake air is too warm, the chassis might overheat, leading
to the TCX1000-RDM20 temperature monitor shutting down the device to protect the
hardware components.
Table 16 on page 34 provides the required environmental conditions for normal operation
of the TCX1000-RDM20.
Tolerance
No performance degradation up to 6000 feet (1828.8 meters).
Normal operation ensured in relative humidity range of 5% through 85%,
noncondensing.
Short-term operation ensured in relative humidity range of 5% through 90%,
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).
Short-term operation ensured in temperature range of 23° F (–5° C) through
131° F (55° C).
Nonoperating storage temperature in shipping container: –40°F (–40° C)
through 185° F (85° C).
Designed to comply with Zone 4 earthquake requirements per NEBS GR-63-CORE,
Issue 3.
NOTE: Install the TCX1000-RDM20 only in restricted-access areas, such as
dedicated equipment rooms and equipment closets, in accordance with
Articles 110-26 and 110-27 of the National Electrical Code, ANSI/NFPA 70.
