Brocade DCX 8510-4 Backbone Hardware Reference Manual - Manual (Page 116)

Environmental requirements
The following table lists the environmental operating ranges for the Brocade DCX 8510-4. The
requirements for non-operating conditions are also provided for acceptable storage and transportation
environments.
Environmental requirements TABLE 20
Condition Acceptable range during operation Acceptable range during
nonoperation
Ambient temperature 0° to 40°C outside switch (32° to 104°F) -25° to +70°C outside switch(-13° to
158°F)
Humidity 5% to 93% RH noncondensing, at 40° Celsius,
with maximum gradient of 10% per hour 10% to 93% RH noncondensing, at 70°
Celsius
Altitude Up to 3 km (10,000 ft.) above sea level 0 to 12 km (40,000 ft.) above sea level
Shock 20G, 6ms duration, half-sine wave 33G, 11ms duration, half-sine wave
Vibration 0.5G p-p, 5-500 Hz at 1.0 octave/minute 2.0G p-p, 5-500 Hz at 1.0 octave/
minute
Airflow 250 cu ft/min. (425 cu m/hr) None required
Heat dissipation (fully
loaded with QSFPs) 1195 Watts or 4078 BTU/hr (192 port
configuration) Not applicable
NOTE
The 0° to 40° Celsius range applies to the ambient air temperature at the air intake vents on the
nonport side of the Brocade DCX 8510-4.The temperature inside the Brocade DCX 8510-4 can be up
to 75° Celsius during operation. If the internal temperature range exceeds the operating ranges of the
components, the LEDs, error messages, and Fabric Watch alerts will indicate a problem. Use the
tempShow command or Fabric Watch commands to view temperature status.
Fibre Channel port specifications
The Fibre Channel ports in the Brocade DCX 8510-4 support full duplex link speeds at 2, 4, 8, 10, or
16 Gbps inbound and outbound, automatically negotiating to the highest common speed of all devices
connected to the port.
The ports are compatible with optical SWL (short wavelength: approximately 850 nm), optical LWL
(long wavelength: approximately 1310 nm), and optical ELWL (extended long wavelength:
approximately 1550 nm) laser transmitter SFPs, SFP+s, mSFPs (FC8-64 only), and QSFPs (FC16-64
only). The strength of the signal is determined by the type of SFP, SFP+, mSFP, or QSFP in use.
mSFPs and QSFPs support only SWL.
