DC SAN Backbone Director hardware reference guide 107
Environmental requirements
Table 25
lists the environmental operating ranges for the DC Director. The requirements for non-operating
conditions are also provided for acceptable storage and transportation environments.
NOTE:
The 10° to 40° Celsius range applies to the ambient air temperature at the air intake vents on the
nonport side of the DC Director.
The temperature inside the DC Director 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 DC Director support full duplex link speeds at 10.51875, 8.50, 4.25, 2.125,
or 1.0625 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 Extended Long Wavelength (ELWL) laser transmitter SFPs and
XFPs (FC10-6 only) (approximately 1550 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
” on page 127.
