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. Table 15.

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. Table 16.

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

are
capable

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

this
port
to

to
the
switch.
