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 using an RJ-45 connector.
The serial port can be used to connect to a workstation to configure the switch IP
address before connecting the switch to a fabric or IP network. The serial port's
parameters are fixed at 9600 baud, 8 data bits, and no parity, with flow control set
to None.
This connector is for initial IP address configuration and for recovery of the switch
to its factory default settings if Flash memory contents are lost. The serial port is
not intended for performance of normal administration or maintenance functions.
You should only use this port to connect a terminal to the port to re-initialize the
switch defaults, restoring the switch to its factory configuration. This is required to
restore switch passwords to a known state and allow you to assign an IP address
to the switch.
Table 15 lists the serial cable pinouts.

Power supply specifications

The power supplies are universal and capable of functioning worldwide without
voltage jumpers or switches. They meet IEC 61000-4-5 surge voltage requirements
and are autoranging in terms of accommodating input voltages and line frequencies.
Each power supply has a built-in fan for cooling, pushing air towards the port side
of the switch.
Table 16 lists the power supply specifications for the switch.
