Heat dissipation
NOTE: The 10° to 40°C range applies to the ambient air temperature at the air intake vents on
the non-port side of the DC04 SAN Director. The temperature inside the product chassis can be
up to 75° C 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 FC ports in the DC04 SAN Director support full-duplex link speeds at 10.51875, 8.50, 4.25,
2.125, or 1.0625 Gb/s 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 1,310 nm), and Extended Long Wavelength (ELWL) laser
transmitter SFPs and XFPs (FC10-6 only) (approximately 1,550 nm). The strength of the signal is
determined by the type of SFP or XFP in use.
The ports are universal and self-configuring, capable of becoming F_Ports (fabric ports), FL_Ports
(fabric loop enabled), or E_Ports (expansion ports).
The ports meet all required safety standards. For a listing of these standards, see Regulatory
compliance and safety notices (page 119).
Data transmission ranges
Table 29 (page 109) and Table 30 (page 109) provide the data transmission ranges for different
cable types and port speeds.
