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 XFPs (FC10-6
only). The strength of the signal is determined by the type of SFP, SFP+, mSFP or XFP in use. mSFPs
support only SWL.
QSFP ports are fixed speed 16 Gbps ports designed to be used with specialized quad (4x16)
connections and cables. They support only SWL.
The ports are universal and self-configuring, capable of becoming F_Ports (fabric ports), FL_Ports
(fabric loop-enabled ports), or E_Ports (expansion ports).
The ports meet all required safety standards. For a listing of these standards, see “Regulatory
compliance” .
Power specifications
The power subsystem is a redundant +48V DC power distribution system with a provision for up to
two 2000-watt, 48V DC bulk power supplies. Two bulk power supplies produce the intermediate
distribution voltage in the distributed power system.
If circuits are available, 200-240 VAC (220 VAC nominal) is always recommended as a greener and
more efficient alternative.
Airflow 250 cu ft/min.
(425 cu m/hr) None required
Heat dissipation
(fully loaded with QSFPs) 1195 Watts or 4078 BTU/hr
