NOTE:
The 10° to 40° Celsius range applies to the ambient air temperature at the air intake vents on the
non-port side of the DC SAN Director or DC04 SAN Director. The temperature inside the product
chassis 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 SAN Director and 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 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.
