Chapter 3. Operating the switch This chapter provides the following information: v "Powering the switch on and off" v "Interpreting LED activity" v "LED patterns" on page 23 v "POST and boot specifications" on page 25 v "Interpreting POST results" on page 26 v "Customer field replaceable units (CRUs/FRUs)" on page 31 v "Maintaining the switch" on page 26 v "Managing the switch" on page 33 v Powering the switch on and off See Chapter 2, "Installing and configuring the switch," on page 7 for initial setup instructions before powering the switch on for the first time. Once the switch has been properly configured, follow these instructions to power the switch on and off. To power the switch on, connect one or both power cords to the power connectors on the power supplies and to a power source; then, set the AC power switches to ″|″. Power is supplied to the switch as soon as the first power supply is connected and powered on. The switch runs POST by default each time it is powered on; it requires a minimum of three minutes to boot and complete POST. To power the switch off, power off both power supplies by setting each AC power switch to ″O″. All devices are returned to their initial state the next time the switch is powered on. Interpreting LED activity System activity and status can be determined through the activity of the LEDs on the switch. There are three possible LED states: no light, a steady light, and a flashing light. The steady lights and flashing lights can be green or amber. The LEDs flash either of these colors during boot, POST, or other diagnostic tests. This is normal and does not indicate a problem unless the LEDs do not indicate a healthy state after all boot processes and diagnostic tests are complete. The switch has the following LEDs: v System power LED-One LED (green) to indicate system power v System status LED-One LED (green/amber) to indicate system status v Ethernet status LEDs-Two LEDs to indicate speed and link status v Port status LEDs-40 LEDs (green/amber) to indicate status for each port v One power supply status LED on each power supply, to the left of the ON/OFF rocker switch © Copyright IBM Corp. 2008 21

Operating
the
switch
This
chapter
provides

“Powering
the
switch
on
and
off”

“Interpreting
LED
activity”
v

v
Powering
the
switch
on
and
off
See
Chapter
2,
“Installing
and
configuring
the
switch,”
on
page
7
for
initial
setup
instructions
before
powering
the
switch
on
for
the
first
time.
Once
the
switch
has
been
properly
configured,
follow
these
instructions
to
power
the
switch
on
and
off.
To
power
the
switch
on,
connect
one
or
both
power
cords
to
the
power
connectors
on
the
power
supplies
and
to
a
power
source;
then,
set
the
AC
power
switches
to
″
|
″
.
Power
is
supplied
to
the
switch
as
soon
as
the
first
power
supply
is
connected
and
powered
on.
The
switch
runs
POST
by
default
each
time
it
is
powered
on;
it
requires
a
minimum
of
three
minutes
to
boot
and
complete
POST.
To
power
the
switch
off,
power
off
both
power
supplies
by
setting
each
AC
power
switch
to
″
O
″
.
All
devices
are
returned
to
their
initial
state
the
next
time
the
switch
is
powered
on.
Interpreting
LED
activity
System
activity
and
status
can
be
determined
through
the
activity
of
the
LEDs
on
the
switch.
There
are
three
possible
LED
states:
no
light,
a
steady
light,
and
a
flashing
light.
The
steady
lights
and
flashing
lights
can
be
green
or
amber.
The
LEDs
flash
either
of
these
colors
during
boot,
POST,
or
other
diagnostic
tests.
This
is
normal
and
does
not
indicate
a
problem
unless
the
LEDs
do
not
indicate
a
healthy
state
after
all
boot
processes
and
diagnostic
tests
are
complete.
The
switch
has
the
following
LEDs:
v
System
power
LED–One
LED
(green)
to
indicate
system
power
v
System
status
LED–One
LED
