Fibre Channel port specifications
The Fibre Channel ports in the switch are compatible with SWL, LWL, and ELWL
SFPs. The strength of the signal is determined by the type of SFP in use. The ports
are capable of operating at 1, 2, 4 and 8 Gbps, and are able to autosense the
highest speed capable for all attached devices. The ports meet all required safety
standards.
Serial port specifications
The serial port is located on the port side of the switch as a RJ-45 connector,
designed to connect to a DTE port. Use the serial port to connect to a computer
workstation to configure the switch IP address without connecting to the fabric.
The serial port’s parameters are 9600 baud, 8 data bits, no parity, 1 stop bit, and no
flow control.
Power supply specifications
The power supply is universal and capable of functioning worldwide without
using voltage jumpers or switches. It meets IEC 61000-4-5 surge voltage
requirements and is autoranging in terms of accommodating input voltages and
line frequencies. The power supply has its own built-in fan for cooling, pushing
the air toward the port side of the switch. The power supply is not removable.
Table 15 lists the power supply specifications for the switch.
