Handling the Switch
To
prevent
electrostatic
damage,
attach
an
electrostatic
discharge
(ESD)
wrist
strap
to
your
wrist
before
handling
the
switch.
Unpacking the Switch
Unpack
the
switch
as
follows:
1. Remove
the
packing
material
protecting
the
switch.
2. Remove
the
switch
from
the
non
‐
conductive
bag.
3. Perform
a
visual
inspection
of
the
switch
for
any
signs
of
physical
damage.
Contact
Enterasys
Networks
if
there
are
any
signs
of
damage.
See
“Getting
Help”
for
more
information
on
contacting
Enterasys
Networks.
Connecting Power to the Switch
You
can
connect
an
A2
switch
to
a
single,
primary
source
of
power,
or
to
two
sources
of
power
for
redundancy.
The
following
redundant
power
supplies
are
available
for
purchase
from
Enterasys
Networks
for
connection
to
an
A2
switch:
• C2RPS
‐
PSM,
a
150
watt
DC
power
supply
capable
of
providing
power
to
a
fully
‐
loaded
non
‐
PoE
switch.
• C2RPS
‐
POE
(A2H124
‐
24P
and
A2H124
‐
48P
only),
500
watt
DC
power
supply
for
PoE
switches.
To
power
‐
up
your
A2
switch:
1. If
you
are
connecting
a
redundant
power
supply,
attach
the
C2RPS
‐
PSM
cable
(for
non
PoE)
or
C2RPS
‐
POE
cable
(for
PoE)
from
your
redundant
power
supply
to
the
A2
switch’s
redundant
power
connector.
2. Attach
the
AC
power
cord
to
the
A2
switch’s
AC
input
power
connector.
3. Plug
the
redundant
power
supply
(if
applicable)
and
the
A2
switch
AC
power
cords
into
dedicated,
grounded
AC
outlets.
4. Once
power
is
connected,
verify
that
the
RPS
power
LED
turns
green,
and
the
CPU
(system)
LED
turns
amber
until
the
A2
switch
finishes
its
initialization.
5. If
the
initialization
process
is
successful,
the
CPU
LED
turns
green.
If
the
CPU
LED
does
not
turn
green,
refer
to
the
SecureStack
A2
Hardware
Installation
Guide
associated
with
your
A2
switch
for
troubleshooting
information.
Completing the Setup and Downloading the Latest
Firmware
Once
you
have
connected
power
to
the
A2
switch
and
verified
LED
activity,
you
can
complete
the
setup
process
as
follows.
Refer
to
the
SecureStack
A2
Hardware
Installation
Guide
associated
with
your
A2
switch
for
more
information.
1. Determine
the
latest
A2
firmware
version
by
visiting
the
Enterasys
Networks
download
site
at:
http://secure.enterasys.com/services/support/downloads/software
2. Connect
the
switch
to
the
network.
3. Connect
a
management
station
to
the
console
port.
4. Verify
that
the
network
devices
connected
to
the
switch
ports
are
powered
on,
and
that
each
link/activity
LED
is
on
(solid
green
or
blinking
green).
5. At
the
device
connected
to
the
console
port,
perform
the
following:
a. Enter
admin
for
Username.
Caution:
The switch can be damaged by electrostatic
discharge.
Note:
Enterasys Networks recommends installing
any components before powering on your switch.
Note:
To take full advantage of redundancy, each power
supply should be plugged-in to a separate, dedicated AC
outlet.
b. At
the
Password
prompt,
press
ENTER
(RETURN).
c. At
the
command
prompt,
determine
if
the
latest
firmware
image
is
loaded
on
the
switch
by
entering
this
command:
show version
d. If
the
output
(under
FW
Version
)
displays
an
older
version
number
than
that
determined
in
Step
1,
download
and
activate
the
new
version
as
directed
on
the
download
website.
(Alternatively,
you
can
use
the
CLI
command
listed
in
Table 1
.)
Basic Setup Commands
Table 1

basic
configurations
for
your
A2
switch.
