A Fibre Channel port specifications NOTE The 0 to 40 Celsius range applies to the ambient air temperature at the air intake vents on the nonport side of the PowerConnect B-DCX-4S. The temperature inside the PowerConnect B-DCX-4S 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 PowerConnect B-DCX-4S support full duplex link speeds at 10, 8, 4, 2, or 1 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". 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. The power specifications in Table 20 are calculated for fully loaded systems with two power supplies, four FC8-48 port blades, two CP8 blades, two CR4S-8 blades, and two blower assemblies. The use of application and/or encryption blades will consume additional power. If the option is available, 220 VAC is recommended and a greener and more efficient alternative. NOTE If any of the following blades are used, 220 VAC is required: FS8-18, FX8-24, FCOE10-24. .TABLE 20 Power specifications Specification Value Voltage Power supply output (each) Input frequency Range: 85 - 264 VAC Auto-volt, Nominal: 100 to 240 VAC Low line (85- 132 VAC), 1000W; High line (180 - 264 VAC), 2000W Range: 47-63 Hz; Nominal: 50 - 60 Hz 90 PowerConnect B-DCX-4S Backbone Hardware Reference Manual 53-1001808-01
